`. The hint text used as the count message now appears directly after the `

If you're not using Nunjucks macros, then you should:

- move all classes and attributes from the form group `<div>` to the component wrapper `<div>`
- remove the opening `<div>` and closing `</div>` tags used by the form group
- check the count message is now directly after the `<textarea>`

The following example shows some HTML and the difference once it’s updated.

HTML before:

```html
<div class="govuk-character-count" data-module="govuk-character-count" data-maxlength="100">
  <div class="govuk-form-group">
    
  </div>
  
</div>
```

HTML after:

```html
<div class="govuk-form-group govuk-character-count" data-module="govuk-character-count" data-maxlength="100">
  
</div>
```

Check your changes against [the Character count example in the Design System](https://design-system.service.gov.uk/components/character-count/#character-count-example) to make sure you’ve correctly implemented them.

This change was introduced in [pull request #4566: Use Character count `formGroup` as module wrapper](https://github.com/alphagov/govuk-frontend/pull/4566).

#### Remove redundant `role` attributes from elements

We've made minor changes to the HTML of the page template, as well as the header, footer and pagination components.

You can update your HTML to remove the `role` attribute from some elements. These include the:

- `main` role on the `main` element in the template
- `banner` role on the `header` element in the Header component
- `contentinfo` role on the `footer` element in the Footer component
- `navigation` role on the `nav` element in the Pagination component

These roles were present to support legacy browsers, such as older versions of Internet Explorer. GOV.UK Frontend no longer supports these browsers, so you can now remove these roles.

You do not need to change anything if you're using the Nunjucks versions of the page template or these components,

This change was introduced in [pull request #4854: Remove redundant `role` attributes](https://github.com/alphagov/govuk-frontend/pull/4854).

### Fixes

We've fixed an upstream issue in the [cssnano npm package](https://www.npmjs.com/package/cssnano) that caused elements with transparency to render incorrectly in Internet Explorer 11. This affected the pre-compiled CSS files in the [GOV.UK Frontend npm package](https://www.npmjs.com/package/govuk-frontend) and [GitHub releases](https://github.com/alphagov/govuk-frontend/releases) for versions 5.0, 5.1 and 5.2. This was fixed in:

- [#1573: feat: add preset and plugin options for browserslist](https://github.com/cssnano/cssnano/pull/1573) in the cssnano repository
- [#4829: Bump the postcss group with 2 updates](https://github.com/alphagov/govuk-frontend/pull/4829)

We've made fixes to GOV.UK Frontend in the following pull requests:

- [#4811: Use `KeyboardEvent.key` over deprecated `KeyboardEvent.keyCode` in the Tabs component](https://github.com/alphagov/govuk-frontend/pull/4811)
- [#4812: Use `KeyboardEvent.key` over deprecated `KeyboardEvent.keyCode` in the Button component](https://github.com/alphagov/govuk-frontend/pull/4812)
- [#4813: Remove deprecated `KeyboardEvent` properties from the Exit this Page component](https://github.com/alphagov/govuk-frontend/pull/4813)
- [#4855: Fix mobile product name being misaligned in new type scale](https://github.com/alphagov/govuk-frontend/pull/4855)

## 5.2.0 (Feature release)

In this release, we’ve adjusted our responsive type scale, which is available behind a feature flag. The type scale change is to make text easier to read on smaller screens. We’ve also deprecated the `useTudorCrown` parameter.

To install this version with npm, run `npm install govuk-frontend@5.2.0`. You can also find more information about [how to stay up to date](https://frontend.design-system.service.gov.uk/staying-up-to-date/#updating-to-the-latest-version) in our documentation.

### New features

#### We've adjusted our responsive type scale

We've made the following adjustments to our responsive type scale:

- point 16 now returns 16px across all screen sizes
- point 19 now returns 19px across all screen sizes
- point 24 remains as 24px on large screens
- point 24 now returns 21px on small screens instead of 18px and has a line height 25px instead of 20px
- point 27 remains as 27px on large screens
- point 27 now returns 21px on small screens instead of 18px and has a line height 25px instead of 20px
- point 36 remains as 27px on large screens
- point 36 now returns 27px on small screens instead of 24px and has a line height 30px instead of 25px

To enable these changes, set the feature flag variable `$govuk-new-typography-scale` to `true` before you import GOV.UK Frontend in your Sass files:

```scss
// application.scss
$govuk-new-typography-scale: true;
@import "govuk-frontend/all";
```

If your service uses custom elements made using GOV.UK Frontend, test your service against the new typography scale to assess if you need to make any adjustments.

You can read more on upgrading your service to the new type scale in our [upgrade guide](https://design-system.service.gov.uk/get-started/new-type-scale/).

This change was introduced in [pull request #2421: Adjust the responsive type scale](https://github.com/alphagov/govuk-frontend/pull/2421)

#### Insert custom HTML into component form group wrappers

You can now insert custom HTML into form group wrappers for all components with form fields.

```njk
govukInput({
  formGroup: {
    beforeInput: {
      html: "example"
    },
    afterInput: {
      html: "example"
    },
  }
})
```

This change was introduced in [pull request #4567: Add `beforeInput(s)` and `beforeInput(s)` options to form groups](https://github.com/alphagov/govuk-frontend/pull/4567).

### Deprecated features

#### Stop using the `useTudorCrown` parameter in the Heading component

The rollout for the revised GOV.UK logo has started and the Tudor crown logo is now shown by default. We’ve deprecated the `useTudorCrown` parameter and will remove it in the next major release.

You can now remove the `useTudorCrown` parameter, along with any other adjustments made to display the Tudor crown logo in your service.

This change was introduced in [pull request #4740: Make Tudor Crown logo the default](https://github.com/alphagov/govuk-frontend/pull/4740)

### Fixes

We've made fixes to GOV.UK Frontend in the following pull requests:

- [#4768: Fix z-index of inputs in Radios and Checkboxes component](https://github.com/alphagov/govuk-frontend/pull/4768)
- [#4784: Fix LibSass `calc()` compatibility in Radios and Checkboxes](https://github.com/alphagov/govuk-frontend/pull/4784)

## 5.1.0 (Feature release)

To install this version with npm, run `npm install govuk-frontend@5.1.0`. You can also find more information about [how to stay up to date in our documentation](https://frontend.design-system.service.gov.uk/staying-up-to-date/#updating-to-the-latest-version).

### New features

#### Update to the new GOV.UK logo

The GOV.UK logo has been updated to reflect the changing of the monarch. King Charles III uses the Tudor Crown, rather than the St Edward’s Crown chosen by Queen Elizabeth II.

If your service uses GOV.UK branding, you must update your service between 19 February and 1 March 2024 to use the new logo.

These changes were made in the following pull requests:

- [#4354: Implement the Tudor crown favicons (v5.x)](https://github.com/alphagov/govuk-frontend/pull/4354)
- [#4297: Implement the Tudor crown in the Header component (v5.x)](https://github.com/alphagov/govuk-frontend/pull/4297)

#### Include the new logo assets

Multiple new image assets are included in this release. You’ll need to copy these to your service's image assets folder if they’re not being used directly from the Frontend package. By default this folder is located at `/assets/images`.

If you’re using Nunjucks, the asset path may have been changed by the `assetPath` global variable or `assetsPath` parameter on the header component.

Copy the following files from `/dist/assets/images` into your assets folder. Any images with the same name as an existing image can be safely overwritten.

- favicon.ico
- favicon.svg
- govuk-icon-180.png
- govuk-icon-192.png
- govuk-icon-512.png
- govuk-icon-mask.svg
- govuk-opengraph-image.png

#### Update the logo in the header of your page

If you’re using the `govukHeader` Nunjucks macro in your service, add the `useTudorCrown` parameter to the macro instantiation. This will become the default in a future version of GOV.UK Frontend.

```nunjucks
{{ govukHeader({
  ...
  useTudorCrown: true
}) }}
```

If you’re not using the Nunjucks macro, locate the SVG code for the existing logo and replace it with this updated SVG.

```html
<svg
  focusable="false"
  role="img"
  class="govuk-header__logotype"

#### Add attributes to component form group wrappers

You can now add attributes to the form group wrapper for all components with form fields.

```njk
govukRadios({
  formGroup: {
    attributes: {
      "data-attribute": "value"
    }
  }
})
```

This change was introduced in [pull request #4565: Allow `attributes` option on form groups](https://github.com/alphagov/govuk-frontend/pull/4565).

#### Use tabular numbers with the `govuk-font-tabular-numbers` mixin

You can now use tabular numbers in your authored Sass by including the new `govuk-font-tabular-numbers` mixin.

Previously, you’d use the `govuk-font` mixin with the `$tabular` parameter. However, the `govuk-font` mixin includes styles unrelated to tabular numbers, which are not needed in some contexts.

These additional styles are not included if you use `govuk-font-tabular-numbers`. Switching to the new mixin can reduce the size of your compiled CSS without affecting the appearance of pages.

This change was introduced in [pull request #4307: Refactor tabular number activation into their own mixin](https://github.com/alphagov/govuk-frontend/pull/4307).

### Recommended changes

#### Replace instances of `govuk-typography-responsive` with `govuk-font-size`

We've renamed the Sass mixin `govuk-typography-responsive` to `govuk-font-size` and have deprecated `govuk-typography-responsive`. You can still use `govuk-typography-responsive`, but we'll remove it in a future breaking release (GOV.UK Frontend v6.0.0).

This is an experimental change to see if the name `govuk-font-size` better communicates the Sass mixin's intended use than the name `govuk-typography-responsive`.

We're interested in feedback from the community on this name change, so please let us know what you think [through our usual channels](https://design-system.service.gov.uk/get-in-touch/).

This change was introduced in [pull request #4291: Rename `govuk-typography-responsive` to `govuk-font-size`](https://github.com/alphagov/govuk-frontend/pull/4291).

#### Remove the `aria-labelledby` attribute from accordion sections

If you’re not using our Nunjucks macros, remove the `aria-labelledby` attribute from all accordion sections (`div` elements that have the `govuk-accordion__section-content` class).

This change was introduced in [pull request #4628: Remove `aria-labelledby` from accordion sections](https://github.com/alphagov/govuk-frontend/pull/4628).

### Deprecated features

#### Stop using the `element` parameter on buttons

We’ve deprecated the `element` Nunjucks parameter and will remove it in the next major release.

In the future, if the `href` parameter is set the component will automatically use the `<a>` element. If the `href` parameter is not set the component will automatically use the `<button>` element. It will not be possible to override this change.

This change was introduced in [pull request #4646: Deprecate `element` parameter on button component](https://github.com/alphagov/govuk-frontend/pull/4646).

#### Stop using `govuk-body-xs`, `govuk-!-font-size-14` and '14' on the type scale

We’ve deprecated point 14 (14px large screens, 12px small screens) on the GOV.UK Frontend responsive type scale, including font override classes that use point 14:

- `govuk-body-xs`
- `govuk-!-font-size-14`

We’ll remove these classes and point 14 on the type scale in the next major release, GOV.UK Frontend release v6.0.0. With this change in the v6.0.0 release, you’ll no longer be able to call the Sass mixins `govuk-font` or `govuk-font-size` with `$size` set to '14'.

This change was introduced in [#4649: Deprecate 14 on the type scale](https://github.com/alphagov/govuk-frontend/pull/4649) and [#4713: Ensure `govuk-font-size()` handles string keys](https://github.com/alphagov/govuk-frontend/pull/4713).

### Fixes

We've made fixes to GOV.UK Frontend in the following pull requests:

- [#4157: Dynamically position text within input prefixes and suffixes](https://github.com/alphagov/govuk-frontend/pull/4157)
- [#4150: Header menu button position refactor](https://github.com/alphagov/govuk-frontend/pull/4150)
- [#4093: Refactor positioning of radios and checkboxes](https://github.com/alphagov/govuk-frontend/pull/4093)
- [#4562: Use CSS custom properties for component `matchMedia()`](https://github.com/alphagov/govuk-frontend/pull/4562)

## 5.0.0 (Breaking release)

You can find a summary of the main [changes to GOV.UK Frontend v5](https://frontend.design-system.service.gov.uk/changes-to-govuk-frontend-v5/) on the Frontend site. It's important to note [our old frameworks (such as GOV.UK Elements)](https://frontend.design-system.service.gov.uk/v4/migrating-from-legacy-products/) are no longer compatible with this release. It also stops Internet Explorer 11 from running GOV.UK Frontend JavaScript and removes support completely for Internet Explorer 8 to 10.

Your service will not stop working in Internet Explorer 11, but components will look and behave differently without JavaScript. Read more about [how we provide support for different browsers](https://frontend.design-system.service.gov.uk/browser-support/).

Service teams should be [using a progressive enhancement approach](https://www.gov.uk/service-manual/technology/using-progressive-enhancement) to make sure users can still access any content and complete their tasks.

If you still need to provide support for older versions of Internet Explorer, you should stay on the latest [GOV.UK Frontend v4 release](https://github.com/alphagov/govuk-frontend/releases).

If you need it, we have a checklist for the changes you might need to make for v5, which you can [view](https://docs.google.com/spreadsheets/d/1Qt-9kLcB_ONp4WOTI61i69P3q7Ymw0ziA5YNUqNkImE/edit) or [copy (needs a Google account)](https://docs.google.com/spreadsheets/d/1Qt-9kLcB_ONp4WOTI61i69P3q7Ymw0ziA5YNUqNkImE/copy).

### Breaking changes

You must make the following changes when you migrate to this release, or your service might break.

#### Update package file paths for Sass

In preparation for additional build targets, we've moved our package files into a directory called `dist`.

Replace `govuk-frontend/govuk` with `govuk-frontend/dist/govuk` in any [Sass](https://sass-lang.com/) `@import` paths.

For example:

```scss
@import "node_modules/govuk-frontend/dist/govuk/all";
```

If you've added [`node_modules/govuk-frontend` as a Sass import path](https://frontend.design-system.service.gov.uk/importing-css-assets-and-javascript/#simplify-sass-import-paths), update it with the `/dist` suffix:

```js
loadPaths: [
  'node_modules/govuk-frontend/dist'
]
```

If you're building your Sass code through Rails Assets Pipeline or Sprockets, refer to the section 'Update package file paths in Rails Assets Pipeline or Sprockets'.

Refer to the [detailed guidance on importing using Sass](https://frontend.design-system.service.gov.uk/importing-css-assets-and-javascript/#import-using-sass).

These changes were introduced in [#3498: Remove built `dist` and `package` from source](https://github.com/alphagov/govuk-frontend/pull/3498)

#### Update package file paths for Nunjucks

In preparation for additional build targets, we've moved our package files into a directory called `dist`.

Replace `govuk-frontend` with `govuk-frontend/dist` in any [`nunjucks.configure()`](https://mozilla.github.io/nunjucks/api.html#configure) search paths:

```js
nunjucks.configure([
  'node_modules/govuk-frontend/dist'
])
```

Refer to the [detailed guidance on using Nunjucks](https://frontend.design-system.service.gov.uk/use-nunjucks/#set-up-nunjucks-and-use-the-page-template).

These changes were made in the following pull requests:

- [#3491: Update Review app to import `govuk-frontend` via local package](https://github.com/alphagov/govuk-frontend/pull/3491)
- [#3498: Remove built `dist` and `package` from source](https://github.com/alphagov/govuk-frontend/pull/3498)

#### Update package file paths for assets such as images and fonts

In preparation for additional build targets, we've moved our package files into a directory called `dist`.

If you're [serving the assets from the GOV.UK Frontend assets folder](https://frontend.design-system.service.gov.uk/v4/importing-css-assets-and-javascript/#serve-the-assets-from-the-gov-uk-frontend-assets-folder-recommended) (`node_modules/govuk-frontend/govuk/assets`), [update your routing to the new assets path ](https://frontend.design-system.service.gov.uk/importing-css-assets-and-javascript/#serve-the-assets-from-the-gov-uk-frontend-assets-folder-recommended): `node_modules/govuk-frontend/dist/govuk/assets`.

Refer to the [detailed guidance on importing assets](https://frontend.design-system.service.gov.uk/importing-css-assets-and-javascript/#font-and-image-assets).

These changes were introduced in [#3498: Remove built `dist` and `package` from source](https://github.com/alphagov/govuk-frontend/pull/3498)

#### Update package file paths in Rails Assets Pipeline or Sprockets

In preparation for additional build targets, we've moved our package files into a directory called `dist`.

Update the  `node_modules/govuk-frontend` part of the path to `node_modules/govuk-frontend/dist`, if you've added the path to GOV.UK Frontend package inside `node_modules` to:

- [Rails Assets Pipeline search path](https://guides.rubyonrails.org/asset_pipeline.html#search-paths) using `Rails.application.config.assets.paths`
- Sprockets using `append_path`

These changes were introduced in [#3498: Remove built `dist` and `package` from source](https://github.com/alphagov/govuk-frontend/pull/3498)

#### Update package file paths if including JavaScript directly

In preparation for additional build targets, we've moved our package files into a directory called `dist`.

If you've [set up your routing to serve GOV.UK Frontend's `all.js` file from `node_modules`](https://frontend.design-system.service.gov.uk/v4/importing-css-assets-and-javascript/#add-the-javascript-file-to-your-html), update the path you're serving to `node_modules/govuk-frontend/dist/govuk/govuk-frontend.min.js`.

Update any `<script>` tag with the new path and filename, if necessary. Make sure they have a `type="module"` attribute. For example:

```html
<script type="module" src="{path-to-javascript}/govuk-frontend.min.js"></script>
```

Replace `<script>window.GOVUKFrontend.initAll()</script>` to import and initialise GOV.UK Frontend using ES modules:

```html
<script type="module">
  import { initAll } from '{path-to-javascript}/govuk-frontend.min.js'

initAll()
</script>
```

Refer to the [detailed guidance on importing JavaScript](https://frontend.design-system.service.gov.uk/importing-css-assets-and-javascript/#add-the-javascript-file-to-your-html).

These changes were introduced in [#3498: Remove built `dist` and `package` from source](https://github.com/alphagov/govuk-frontend/pull/3498)

#### Update package file paths for Node.js and other bundlers

In preparation for additional build targets, we've moved our package files into a directory called `dist`.

If you're importing GOV.UK Frontend using `import ... from 'govuk-frontend'` or `require('govuk-frontend')`, you have nothing to change.

If you're using `import` to import individual components, replace `govuk-frontend/govuk` with `govuk-frontend/dist/govuk`. For example:

```js
import Button from 'govuk-frontend/dist/govuk/components/button/button.mjs'
```

If you're using `require` to import individual components, replace `govuk-frontend/govuk` with `govuk-frontend/dist/govuk` and update the file name to `<COMPONENT_NAME>.bundle.js`. For example:

```js
const Button = require('govuk-frontend/dist/govuk/components/button/button.bundle.js')
```

Refer to the [detailed guidance on importing JavaScript](https://frontend.design-system.service.gov.uk/importing-css-assets-and-javascript/#import-javascript-using-a-bundler).

These changes were introduced in [#3498: Remove built `dist` and `package` from source](https://github.com/alphagov/govuk-frontend/pull/3498)

#### Verify your code does not rely on polyfills we have now removed

We have removed polyfills for Internet Explorer 8 to 11:

- `DOMTokenList`, `Element.prototype.classList`, `Element.prototype.closest`, `Element.prototype.matches`, and `Event` - required for Internet Explorer 11 and below
- `Element.prototype.dataset` - required for Internet Explorer 10 and below
- `Date.now`, `Document`, `Element`, `Element.prototype.nextElementSibling`, `Element.prototype.previousElementSibling`, `Function.prototype.bind`, `Object.defineProperty`, `String.prototype.trim` and `Window` - required for Internet Explorer 8

However, because these polyfills create or extend global objects ('polluting the global namespace'), you might have other code in your service unintentionally relying on the inclusion of these polyfills. You might need to introduce your own polyfills or rewrite your JavaScript to avoid using the polyfilled features.

These changes were introduced in [pull request #3570: Remove Internet Explorer 8 to 10 JavaScript polyfills, helpers, config](https://github.com/alphagov/govuk-frontend/pull/3570)

#### Stop Internet Explorer 11 and other older browsers running unsupported JavaScript

Add `type="module"` to all HTML `<script>` tags that include or bundle GOV.UK Frontend.

This is to stop Internet Explorer 11 and other older browsers running the JavaScript, which relies on features older browsers might not support and could cause errors.

Please note that `<script>` with `type="module"` [runs JavaScript in a slightly different way](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Modules#other_differences_between_modules_and_standard_scripts) than `<script>` without `type="module". You'll need to assess the impact of these nuances and make sure that:

- when your service code is bundled with GOV.UK Frontend it runs as expected in [strict mode](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Strict_mode)
- if you have any code that needs to run after [GOV.UK](http://gov.uk) Frontend in its own `<script>` tag, you'll need to make sure it's using `type="module"` or [`defer`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script#defer). This is because the tag loading [GOV.UK](http://gov.uk) Frontend will be deferred because of its `type="module"` attribute
- code that needs to run without being deferred, is split into its own file and loaded with a `<script>` tag without `type="module"`

If your service has JavaScript you want to run successfully in Internet Explorer (for example JavaScript for analytics), you will need to load it in a separate `<script>` tag without `type="module"` and make sure its code is compatible with the browsers it should run in (see previous section about polyfills).

These changes were introduced in [pull request #3720: Remove IE11 vendor polyfills](https://github.com/alphagov/govuk-frontend/pull/3720)

#### Update the `<script>` snippet at the top of your `<body>` tag

Page templates now include a new `govuk-frontend-supported` class on the `<body>` tag when GOV.UK Frontend JavaScript components are fully supported.

If you are not using our Nunjucks page template, replace the existing snippet:

```js
<script>document.body.className = ((document.body.className) ? document.body.className + ' js-enabled' : 'js-enabled');</script>
```

with:

```js
<script>document.body.className += ' js-enabled' + ('noModule' in HTMLScriptElement.prototype ? ' govuk-frontend-supported' : '');</script>
```

These changes were introduced in [pull request #3801:

Add class .govuk-frontend-supported for ES modules support] (<https://github.com/alphagov/govuk-frontend/pull/3801>)

#### Update the hash used by your Content Security Policy

If your [Content Security Policy](https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP) uses a hash to let the snippet above run, you'll need to update it from:

```
sha256-+6WnXIl4mbFTCARd8N3COQmT3bJJmo32N8q8ZSQAIcU=
```

to:

```
sha256-GUQ5ad8JK5KmEWmROf3LZd9ge94daqNvd8xy9YS1iDw=
```

These changes were introduced in [pull request #3801:

Add class .govuk-frontend-supported for ES modules support] (<https://github.com/alphagov/govuk-frontend/pull/3801>)

#### Remove calls to component `init` methods from your JavaScript

If you instantiate individual components, remove any calls to component `init` methods,  as initialisation now happens automatically. If you initialise the JavaScript using `window.GOVUKFrontend.initAll()`, you will not need to make any changes.

For example, the following:

```js
new Radios($radio).init()
```

becomes:

```js
new Radios($radio)
```

This change was introduced in [pull request #4011: Remove component init() methods and initialise in constructor](https://github.com/alphagov/govuk-frontend/pull/4011).

#### Remove Internet Explorer 8 stylesheets, settings and mixins

We no longer support Internet Explorer 8 (IE8) in GOV.UK Frontend or provide dedicated stylesheets for the browser. Remove any references to these stylesheets from your HTML.

We've removed the `govuk-if-ie8` and `govuk-not-ie8` mixins, and the `$govuk-is-ie8` and `$govuk-ie8-breakpoint` settings. These were deprecated in [GOV.UK Frontend v4.6.0](https://github.com/alphagov/govuk-frontend/releases/tag/v4.6.0).

You should:

- remove calls to the `govuk-if-ie8` mixin entirely (because the code passed to the mixin was only ever for Internet Explorer 8)
- replace calls to the `govuk-not-ie8` mixin with the contents that were previously passed to the mixin (because now we always want the code passed to the mixin)
- verify your codebase no longer uses these mixins and variables
- remove `ie8` from the `$govuk-suppressed-warnings` list, if present

If a library you depend on is not yet updated and relies on these mixins and variables, as a temporary workaround you can define the following mixins and variables before importing:

```scss
$govuk-is-ie8: false;
$govuk-ie8-breakpoint: ('desktop');
@mixin govuk-if-ie8 {
  @if false {
    @content;
  }
}
@mixin govuk-not-ie8 {@content}
```

This change was introduced in [pull request #3559: Remove IE8-related Sass and CSS build tasks](https://github.com/alphagov/govuk-frontend/pull/3559).

#### Remove references to "Compatibility mode" and related features from your Sass

GOV.UK Frontend is no longer compatible with [our old frameworks](https://frontend.design-system.service.gov.uk/v4/migrating-from-legacy-products/):

- GOV.UK Elements
- GOV.UK Template
- GOV.UK Frontend Toolkit.

You cannot migrate an existing service to GOV.UK Frontend v5.0 if it is still using one of these frameworks -- you'll need to remain on the latest v4.x release until you've finished the migration. Remove any references to these Sass variables and mixins:

- `$govuk-compatibility-govukelements`
- `$govuk-compatibility-govuktemplate`
- `$govuk-compatibility-govukfrontendtoolkit`

- the `govuk-compatibility` mixin which could be used to conditionally output CSS when compatibility mode was enabled
- remove `compatibility-mode` from the `$govuk-suppressed-warnings` list, if present

We've additionally removed features that were managed using the above variables. We've removed the following features and their corresponding variables:

- access to the legacy colour palette using `$govuk-use-legacy-palette`
- access to the legacy font using `$govuk-use-legacy-font`
- use of legacy tabular fonts using `$govuk-font-family-tabular`
- the ability to not use rem font sizes using `$govuk-typography-use-rem`

These changes were introduced in:

- [pull request #3622: Remove compatibility mode variables](https://github.com/alphagov/govuk-frontend/pull/3622)
- [pull request #3602: Remove compatibility-mode mixin](https://github.com/alphagov/govuk-frontend/pull/3602)
- [pull request #3576: Remove legacy colour palette](https://github.com/alphagov/govuk-frontend/pull/3576)
- [pull request #3574: Remove legacy and tabular fonts support](https://github.com/alphagov/govuk-frontend/pull/3574)
- [pull request #3576: Remove $govuk-typography-use-rem setting](https://github.com/alphagov/govuk-frontend/pull/3575)

#### Remove references to font family variables from your Sass

Remove any references to following Sass variables:

- `$govuk-font-family-gds-transport`
- `$govuk-font-family-nta`
- `$govuk-font-family-nta-tabular`

If you were using `$govuk-font-family-gds-transport` to set the font on an element, we recommend using [the `govuk-font` mixin](https://frontend.design-system.service.gov.uk/sass-api-reference/#govuk-font) instead.

This change was introduced in [pull request #3949: Simplify font family settings](https://github.com/alphagov/govuk-frontend/pull/3949).

#### Remove references to `govuk-button--disabled` class from the HTML for the Button component

For the [Button component](https://design-system.service.gov.uk/components/button/), remove any references to the `govuk-button--disabled` class that we deprecated in [GOV.UK Frontend v4.6.0](https://github.com/alphagov/govuk-frontend/releases/tag/v4.6.0).

Use the `disabled` attribute to mark `<button>` and `<input>` elements as being disabled instead.

We no longer support link buttons being disabled or using disabled styles.

This change was introduced in [pull request #3557: Remove deprecated `govuk-button--disabled` class](https://github.com/alphagov/govuk-frontend/pull/3557).

#### Remove references to the JavaScript for the Details component

The [Details component](https://design-system.service.gov.uk/components/details/) no longer uses JavaScript, and is no longer polyfilled in older browsers.

If you are importing the JavaScript for this component individually, remove any references to it.

If you are not using our Nunjucks macros, remove the `data-module="govuk-details"` attribute from all `<details>` elements.

We've styled the details component so content does not look 'broken' in browsers that do not support it. If your service supports these browsers,  you will need to add your own polyfills.

This change was introduced in:

- [pull request #3766: Remove JavaScript from Details component](https://github.com/alphagov/govuk-frontend/pull/3766).
- [pull request #3758: Style details in older browsers](https://github.com/alphagov/govuk-frontend/pull/3758)

#### Update the GOV.UK logo

We've updated the GOV.UK logo to merge the GOV.UK text with the crown graphic. This is to make sure the full logo is always rendered correctly even if parts of the page, such as CSS or the Transport webfont, fail to load. We've also modified styles relating to the logo.

If you're using the `govukHeader` Nunjucks macro you don't need to change anything.

Otherwise, to update to the new logo:

- remove `<span class="govuk-header__logotype-text">` and its content
- remove the `<span class="govuk-header__logotype">` around the svg element
- replace the svg element with [this updated SVG](https://github.com/alphagov/govuk-frontend/blob/70be4b7fcaed406c4aeaf9618da52de1b3ff02db/packages/govuk-frontend/src/govuk/components/header/template.njk#L14-L26), and make sure you also update the class name and attributes

This change was introduced in [pull request #4449: Implement transitional crown in the Header component (v5.0)](https://github.com/alphagov/govuk-frontend/pull/4449).

#### Check your favicons, app icons and OpenGraph image still work

We've changed the names, formats and sizes of icon assets we distribute in Frontend. You will want to check that the correct files are copied in the right place and served at the right URLs.

The following files have been added to the assets folder:

- manifest.json
- images/favicon.svg
- images/govuk-icon-180.png
- images/govuk-icon-192.png
- images/govuk-icon-512.png
- images/govuk-icon-mask.svg

The following files have been removed from the assets folder:

- images/govuk-apple-touch-icon.png
- images/govuk-apple-touch-icon-152x152.png
- images/govuk-apple-touch-icon-167x167.png
- images/govuk-apple-touch-icon-180x180.png
- images/govuk-mask-icon.svg

If you're not using the Nunjucks page template, you will need to replace the list of icons in the template's head with the following:

```html
<link rel="icon" sizes="48x48" href="/assets/images/favicon.ico">
<link rel="icon" sizes="any" href="/assets/images/favicon.svg" type="image/svg+xml">
<link rel="mask-icon" href="/assets/images/govuk-icon-mask.svg" color="#0b0c0c">
<link rel="apple-touch-icon" href="/assets/images/govuk-icon-180.png">
<link rel="manifest" href="/assets/manifest.json">
```

You will need to update the file path to match your assets folder if it's not at the default location.

This change was introduced in [pull request #4445: Implement transitional crown favicons (v5.0)](https://github.com/alphagov/govuk-frontend/pull/4445).

#### Remove the fallback GOV.UK crown logo from the  HTML for the Header component

The [Header component](https://design-system.service.gov.uk/components/header/) previously included a fallback PNG version of the GOV.UK crown logo for Internet Explorer 8. As Frontend no longer supports Internet Explorer 8, we've removed this fallback.

If you're not using the Nunjucks macros, you'll need to remove this fallback from your HTML code. In your Header component:

1. Remove the block of HTML containing the `govuk-header__logotype-crown-fallback-image` image, starting with ``.
2. Remove `` and  `` from around the `govuk-header__logotype-crown` SVG, but don't remove the SVG.
3. Delete the `govuk-logotype-crown.png` file from your assets folder.

You do not need to change any HTML if you're using the supplied Nunjucks macros, but you might still need to remove the `govuk-logotype-crown.png` image depending on [how you are serving the font and image assets](https://frontend.design-system.service.gov.uk/importing-css-assets-and-javascript/#font-and-image-assets).

This change was introduced in [pull request #3641: Remove fallback GOV.UK logo for IE8](https://github.com/alphagov/govuk-frontend/pull/3641).

#### Remove references to `govuk-header__navigation--no-service-name` class from the HTML for the Header component

We've removed the `govuk-header__navigation--no-service-name` class which we deprecated in [GOV.UK Frontend v4.3.0](https://github.com/alphagov/govuk-frontend/releases/tag/v4.3.0).

We no longer supply a dedicated class for headers with navigation but no service name. If you still need this feature, you can reproduce it in your own code using the `govuk-spacing` Sass mixin.

You could:

- add a new `app-header-navigation` class to the header's `<nav>` tag (you can use the `navigationClasses` option for the Header component if you're using Nunjucks)
- add the following styles for this class in your Sass:

```scss
.app-header-navigation {
    padding-top: govuk-spacing(7);
}
```

This change was introduced in [pull request #3595: Remove deprecated `govuk-header__navigation--no-service-name` class](https://github.com/alphagov/govuk-frontend/pull/3595).

#### Add the `hidden` attribute to the mobile menu button in the Header component

We've removed some styles from the `govuk-header__menu-button` class. These styles were included on the [mobile menu button](https://design-system.service.gov.uk/components/header/#header-with-service-name-and-navigation) to avoid introducing a breaking change in [GOV.UK Frontend v4.3.0](https://github.com/alphagov/govuk-frontend/releases/tag/v4.3.0).

If you're not using Nunjucks macros, and have not done so already, add the `hidden` attribute to the button's HTML to ensure it continues working as expected.

You do not need to make any changes if using the Nunjucks macro.

When working correctly, the button should only show on narrow screens when JavaScript is available. It should be hidden on wider screens or if JavaScript is unavailable.

This change was introduced in [pull request #3596: Remove redundant display style from `govuk-header__menu-button`](https://github.com/alphagov/govuk-frontend/pull/3596).

#### Update references to `govuk-header__link--service-name` class from the HTML for the Header component

We've removed the `govuk-header__link--service-name` class which we deprecated in [GOV.UK Frontend v4.2.0](https://github.com/alphagov/govuk-frontend/releases/tag/v4.2.0).

Use the `govuk-header__service-name` class instead.

This change was introduced in [pull request #3594: Remove deprecated `govuk-header__link--service-name` class](https://github.com/alphagov/govuk-frontend/pull/3594).

#### Update references to `govuk-!-margin-static` and `govuk-!-padding-static classes` from the HTML

We've removed the override classes starting with `govuk-!-margin-static` and `govuk-!-padding-static`, which were deprecated in [GOV.UK Frontend v4.3.1](https://github.com/alphagov/govuk-frontend/releases/tag/v4.3.1).

Use the classes starting with `govuk-!-static-margin` and `govuk-!-static-padding` instead.

This change was introduced in [pull request #3593: Remove deprecated static spacing classes](https://github.com/alphagov/govuk-frontend/pull/3593).

#### Update references to the `govuk-warning-text__assistive` class  from the HTML for the Warning Text component

For the [Warning Text component](https://design-system.service.gov.uk/components/warning-text/), we've removed the `govuk-warning-text__assistive` class and its styles from GOV.UK Frontend. This class is unnecessary, as it duplicates the functionality of the `govuk-visually-hidden` class already present in Frontend.

If you're not using Nunjucks macros, update your warning text HTML to replace the `govuk-warning-text__assistive` class with the `govuk-visually-hidden` class.

This change was introduced in [pull request #3569: Remove unnecessary class from Warning Text component](https://github.com/alphagov/govuk-frontend/pull/3569).

#### Check your browser console for component initialisation errors

GOV.UK Frontend JavaScript components now provide errors if you initialise a component incorrectly.

These errors will be:

- logged in the browser console when using the `initAll()` function
- [thrown as exceptions](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/throw) when [instantiating components individually](https://frontend.design-system.service.gov.uk/importing-css-assets-and-javascript/#select-and-initialise-an-individual-component)

To make sure the components behave as intended, we encourage you to check your browser console and address any errors by updating your markup or configuration.

Errors you might see include:

- `SupportError` - when GOV.UK Frontend is not supported in the current browser
- `ElementError` - when component templates have missing or broken HTML elements
- `ConfigError` - when component JavaScript configuration does not match our documentation

These changes were introduced in:

- [pull request #4030: Throw `SupportError` when instantiating components where GOV.UK Frontend is not supported](https://github.com/alphagov/govuk-frontend/pull/4030)
- [pull request #4104: Throw `ElementError` when the module is not of the expected type](<[https://github.com/alphagov/govuk-frontend/pull/4104](https://github.com/alphagov/govuk-frontend/pull/4104)>))
- [pull request #4177: Add `MissingElementError` and use it within the Skip Link](https://github.com/alphagov/govuk-frontend/pull/4177)
- [pull request #4199: Throw `ElementError` when "Exit this page" button is missing](https://github.com/alphagov/govuk-frontend/pull/4199)
- [pull request #4206: Throw `ElementError` when the menu of the header is missing but a toggle is present](https://github.com/alphagov/govuk-frontend/pull/4206)
- [pull request #4236: Throw `ElementError` for missing elements during Character count instantiation](<[https://github.com/alphagov/govuk-frontend/pull/4236](https://github.com/alphagov/govuk-frontend/pull/4236)>))
- [pull request #4261: Throw `ElementError` for missing elements during Character count instantiation](https://github.com/alphagov/govuk-frontend/pull/4261)
- [pull request #4266: Throw errors during accordion initialisation](https://github.com/alphagov/govuk-frontend/pull/4266)
- [pull request #4176: Throw `ConfigError` when component configs are invalid](<[https://github.com/alphagov/govuk-frontend/pull/4176](https://github.com/alphagov/govuk-frontend/pull/4176)>))

#### Check any JavaScript that uses `HTMLElement.getAttribute` to get the disabled state of a button works as expected

The `disabled` attribute on 'Disabled buttons' created using our Nunjucks macros no longer includes a value.

If you are using `$button.getAttribute('disabled')` to check for the disabled attribute in JavaScript, this will now return an empty string. This might cause unexpected behaviour if you are relying on the return value being the string 'disabled' or being [truthy](https://developer.mozilla.org/en-US/docs/Glossary/Truthy).

Instead, we recommend checking for the `disabled` attribute using [`$button.hasAttribute('disabled')`](https://developer.mozilla.org/en-US/docs/Web/API/Element/hasAttribute) or the [`$button.disabled` IDL attribute](https://developer.mozilla.org/en-US/docs/Web/API/HTMLButtonElement/disabled).

This change was introduced in [pull request #2830: Set the boolean disabled attribute consistently in the Button component](https://github.com/alphagov/govuk-frontend/pull/2830).

#### Check that inverse buttons still look as expected if you have customised the brand colour

[Inverse button components](https://design-system.service.gov.uk/components/button/#buttons-on-dark-backgrounds) now use the `$govuk-brand-colour` setting to determine the button's text colour and the button's background tint when hovered or activated. The button will only look different if `$govuk-brand-colour` has been changed from the default.

You can restore the previous blue colour by setting `$govuk-inverse-button-text-colour` before importing the button component's Sass.

```scss
@import "node_modules/govuk-frontend/govuk/base";

$govuk-inverse-button-text-colour: govuk-colour("blue");

@import "node_modules/govuk-frontend/govuk/components/button/index";
```

This change was introduced in [pull request #4043: Add ability to customise inverse button colours](https://github.com/alphagov/govuk-frontend/pull/4043).

#### Check any Selects that have options without explicit values work as expected

The `govukSelect` macro will no longer include an empty value attribute for options that do not have a value set.

If that option is selected, the value of the Select will become the text content of the option, rather than an empty string.

If you need to maintain the existing behaviour, you can set the value to an empty string.

This change was introduced in [pull request #3773: Omit the value attribute from select options with no value](https://github.com/alphagov/govuk-frontend/pull/3773).

### New features

#### Use the Task list component to give users an overview of the tasks they need to complete

The [Task list component](https://design-system.service.gov.uk/components/task-list/) displays all the tasks a user needs to do, and allows users to easily identify which ones are done and which they still need to do.

Each task in the list can have a title, status, link and an optional hint. When a link is added, the whole row is clickable.

This change was introduced in [pull request #2261: Task list component.](https://github.com/alphagov/govuk-frontend/pull/2261).

#### Use the new focus style for links containing non-text content

We've added a new focus style for use with non-text content, such as links containing images and focusable elements that are not form controls. This new style paints a visible yellow and black outline around the entire element, ensuring the focus style is visible in all situations.

For links containing images, we've added the `govuk-link-image` class. You should only use this class on links containing an image. If it also contains text, continue to use `govuk-link` instead.

```html
<a class="govuk-link-image" href="#">
  <img src="..." alt="...">
</a>
```

You can use these styles in your own code by including the `govuk-focused-box` Sass mixin.

This change was introduced in [pull request #3819: Add linked image focus style](https://github.com/alphagov/govuk-frontend/pull/3819).

#### New link styles are now enabled by default

In GOV.UK Frontend v3.12.0 we introduced new link styles which are now enabled by default. They have:

- underlines that are consistently thinner and a bit further away from the link text
- a clearer hover state, where the underline gets thicker to make the link stand out to users

The new link styles are now enabled by default. If you are setting `$govuk-new-link-styles` to `true` in your Sass you can now remove this.

This change was introduced in:

- [pull request #3599: Enable new link styles by default](https://github.com/alphagov/govuk-frontend/pull/3599)
- [pull request #3600: Remove new link styles feature flag](https://github.com/alphagov/govuk-frontend/pull/3600)

#### Customise the colours of inverse buttons

For non-GOV.UK branded websites, you can now change the colours of inverse buttons - buttons intended for use on dark backgrounds.

To change the inverse button's background colour, set the `$govuk-inverse-button-background-colour` Sass variable.

To change the inverse button's text colour, set the `$govuk-inverse-button-text-colour` Sass variable.

```scss
@import "node_modules/govuk-frontend/govuk/base";

$govuk-inverse-button-background-colour: govuk-colour("yellow");
$govuk-inverse-button-text-colour: govuk-colour("black");

@import "node_modules/govuk-frontend/govuk/components/button/index";
```

This change was introduced in [pull request #4043: Add ability to customise inverse button colours](https://github.com/alphagov/govuk-frontend/pull/4043).

#### Precompiled CSS and JavaScript

The precompiled CSS and JavaScript files found in our [GitHub releases](https://github.com/alphagov/govuk-frontend/releases) are now also published to [`govuk-frontend` on npm](https://www.npmjs.com/package/govuk-frontend).

These changes were introduced in:

- [pull request #3726: Default to ES modules with single Rollup config](https://github.com/alphagov/govuk-frontend/pull/3726)
- [pull request #4241: Add new `govuk-frontend.min.css` package bundle](https://github.com/alphagov/govuk-frontend/pull/4241)

#### Check your tags align with design changes to the Tag component

We've changed the design of the [Tag component](https://design-system.service.gov.uk/components/tag/) to improve accessibility and readability.

Text within the tag is no longer bold and uppercase with extra letter spacing. It's now regular 19px text with the first letter of a word capitalised and the rest of the content lowercase. Due to this, there might be changes to the width of existing tags.

The colours have also changed to make them more distinguishable from buttons.

Check your service is using the correct capitalisation in the contents of tags and tags within phase banners.

This change was introduced in:

- [pull request #3502: Tag design changes](https://github.com/alphagov/govuk-frontend/pull/3502)
- [pull request #3731: Remove the first letter modifier from the tag component](https://github.com/alphagov/govuk-frontend/pull/3731)

### Recommended changes

We've recently made some non-breaking changes to GOV.UK Frontend. Implementing these changes will make your service work better.

#### Remove the X-UA-Compatible meta tag

Remove the <meta http-equiv="X-UA-Compatible" content="IE=edge"> meta tag from your page template.

Internet Explorer versions 8, 9 and 10 included a feature that would try to determine if the page was built for an older version of IE and would silently enable compatibility mode, which would modify the rendering engine's behaviour to match the older version of IE. Setting this meta tag prevented that behaviour.

Internet Explorer 11 deprecated this meta tag and defaulted to always using IE11's renderer when the page has a HTML5 doctype (<!DOCTYPE html>).

As Frontend no longer supports Internet Explorer versions older than 11, you can now remove this meta tag.

This change was introduced in [pull request #4434: Remove X-UA-Compatible meta tag](https://github.com/alphagov/govuk-frontend/pull/4434).

#### Update the Pagination component's default `aria-label`

We've updated the default value of the [Pagination component's](https://design-system.service.gov.uk/components/pagination/) `aria-label` to be more descriptive of the contents of the region. If you're using the component's default label, you might wish to update it to the new default of 'Pagination'.

You do not need to change anything if you're using the `govukPagination` Nunjucks macro.

This change was introduced in [pull request #3899: Update default `aria-label` in Pagination component](https://github.com/alphagov/govuk-frontend/pull/3899).

#### Update the Exit this Page button's default text

We've updated the default text of the Exit this Page button. It now includes visually-hidden text to clarify that the button is a safety tool and not a generic method of leaving the current page.

If you are using the component's default text, you might wish to update it to the new value: `<span class="govuk-visually-hidden">Emergency</span> Exit this page`

You do not need to change anything if you're using the `govukExitThisPage` Nunjucks macro.

This change was introduced in [pull request #3989: Update default Exit This Page button text](https://github.com/alphagov/govuk-frontend/pull/3989).

#### Add the `rel` attribute to the Exit this Page button and secondary link

Update the Exit this Page button and secondary link to include a new attribute and value: `rel="nofollow noreferrer"`.

Adding this attribute does 2 things:

- it instructs search engines that your service does not endorse the external website for the purposes of determining search engine rankings
- it instructs web browsers to not send information about your service to the external website

This fixes a potential risk where the external website could detect that a user had visited from a GOV.UK page and play that information back to the user, which could risk a user's personal safety in some contexts.

You do not need to change the Exit this Page button if you're using the `govukExitThisPage` Nunjucks macro. You will still have to update the secondary link manually.

This change was introduced in [pull request #4054: Add `rel` attribute to the Exit this Page button](https://github.com/alphagov/govuk-frontend/pull/4054). Thanks to [Greg Tyler](https://github.com/gregtyler) for reporting this issue.

#### Update titles of the action links inside the Summary Card

If you're not using our Nunjucks macro, we recommend you update the action links :

- of the Summary Card (inside the element with the `govuk-summary-card__actions` class)
- of the Summary List it contains (inside the element with the `govuk-summary-list__actions` class)

You'll need to either:

- append a visually hidden `<span>` with the title of the card, if there's none already
- or append the title of card to the existing visually hidden span, if there was one already

The final link should be structured as such:

```html

<a class="govuk-link <EXISTING_CLASSES>" <EXISTING_ATTRIBUTES>>
  <EXISTING_VISIBLE_TITLE>
  <span class="govuk-visually-hidden">
    <EXISTING_HIDDEN_TEXT_IF_PRESENT>
    <SUMMARY_CARD_TITLE>
  </span>
</a>
```

This is to make sure each link has a unique accessible name, which will help users of assistive technology distinguish them from one another.

This change was introduced in [pull request #3961: Append card title to action links inside of a Summary Card](https://github.com/alphagov/govuk-frontend/pull/3961).

## 4.7.0 (Feature release)

Note: This release was created from the `support/4.x` branch.

### New features

#### Added the Exit This Page component to help users quickly exit a page or service

You can now choose to use the [exit this page](https://design-system.service.gov.uk/components/exit-this-page/) component to help users quickly leave a page or service which contains sensitive information.

This was added in [pull request #2545: Add exit this page component](https://github.com/alphagov/govuk-frontend/pull/2545).

#### Added inverse modifier for buttons on dark backgrounds

You can now choose to use the `govuk-button--inverse` class to style buttons on dark backgrounds with a white background colour.

This change was made in [pull request #3556: Add inverse button styles](https://github.com/alphagov/govuk-frontend/pull/3556).

#### Added inverse modifier for breadcrumbs on dark backgrounds

You can now choose to use the `govuk-breadcrumbs--inverse` class to style breadcrumbs on dark backgrounds with white text, links and arrows.

This change was made in [pull request #3774: Add inverse breadcrumb and back link modifiers and styles](https://github.com/alphagov/govuk-frontend/pull/3774).

#### Added inverse modifier for back links on dark backgrounds

You can now choose to use the `govuk-back-link--inverse` class to style back links on dark backgrounds with white links and arrows.

This change was made in [pull request #3774: Add inverse breadcrumb and back link modifiers and styles](https://github.com/alphagov/govuk-frontend/pull/3774).

### Fixes

We’ve made fixes to GOV.UK Frontend in the following pull requests:

- [#3817: Fix package resolution in Node.js 17+](https://github.com/alphagov/govuk-frontend/pull/3817)
- [#3836: Announce whitespace in screen reader announcements of visually hidden text](https://github.com/alphagov/govuk-frontend/pull/3836)

## 4.6.0 (Feature release)

### New features

#### Updated the appearance of disabled form controls

We’ve updated the disabled state of Text Input, Textarea, Select and File Upload components so it is consistent across browsers and devices. They’re also now consistent with the existing disabled styles for Buttons, Checkboxes, and Radios.

Disabled form controls appear at 50% opacity and with an alternative cursor appearance when hovered over.

This was added in [pull request #3187: Add disabled styles for form controls](https://github.com/alphagov/govuk-frontend/pull/3187).

#### Added a top-level `disabled` parameter to form controls

We’ve updated the Nunjucks macros for Text Input, Textarea, Select and File Upload components to include a top-level `disabled` parameter. This will make it easier to enable the disabled state for these controls.

```nunjucks
{{ govukInput({
  id: "disabled-input",
  name: "disabled-input",
  value: "Unchangeable value",
  disabled: true
}) }}
```

Disabled form controls have poor contrast and can confuse some users, so avoid them if possible.

Only use disabled form controls if research shows it makes the user interface easier to understand.

This was added in [pull request #3187: Add disabled styles for form controls](https://github.com/alphagov/govuk-frontend/pull/3187).

#### Configure whether the Accordion remembers and restores sessions

By default, when a user leaves a page, the [Accordion](https://design-system.service.gov.uk/components/accordion/) will remember the layout of expanded and collapsed sections selected by the user. If the user returns to the page, this layout will be restored and override any sections manually set as expanded in code.

You can now disable this functionality by using the `rememberExpanded` option in the `govukAccordion` Nunjucks macro.

If you're not using the Nunjucks macro, you can disable it using the `data-remember-expanded` HTML attribute.

This was added in [pull request #3342: Add option to disable sessionState in Accordion](https://github.com/alphagov/govuk-frontend/pull/3342).

#### Added `id` parameter to Buttons

We’ve updated the [Button](https://design-system.service.gov.uk/components/button/) Nunjucks macro to include an optional `id` parameter.

```nunjucks
{{ govukButton({
  text: "Save and continue",
  id: "continue-button"
}) }}
```

This was added in [pull request #3344: Adding optional ‘id’ attribute to button component](https://github.com/alphagov/govuk-frontend/pull/3344).

Thanks to [Tom Billington](https://github.com/TomBillingtonUK) for this contribution.

#### Added a modifier for text input styles that accept sequences of digits

We've added a new `.govuk-input--extra-letter-spacing` class for [Text Input](https://design-system.service.gov.uk/components/text-input/). This increases readability of text inputs that receive sequences of digits (like security codes, references or phone numbers).

You can add it through the `classes` option when using Nunjucks, or directly in the `class` attribute of the `<input>` when using HTML.

This was added in [pull request #2230: Add extra letter spacing modifier for inputs](https://github.com/alphagov/govuk-frontend/pull/2230)

### Deprecated features

#### Stop using JavaScript API properties other than the `init` method

We have deprecated all of the JavaScript properties in the API, except for the `init` method for each component. We'll make all of the deprecated JavaScript properties private in [our next main release](https://github.com/alphagov/govuk-frontend/milestone/46).

Please [let us know if you're using parts of the API other than the `init` method by filling in this form](https://docs.google.com/forms/d/e/1FAIpQLSfmH2AitMeouXqB0FWC5p5e6y1TSiFCjmJ8DrVuwfmpRGCaWw/viewform?usp=sf_link). We'll use this information when prioritising future additions to the public API.

This was added in [pull request #3499: Deprecate all JavaScript instance properties the except `init` method](https://github.com/alphagov/govuk-frontend/pull/3499).

#### Stop using the `.govuk-button--disabled` class on buttons

We have deprecated the `.govuk-button--disabled` class and will remove it in the next major release.

If a [Button](https://design-system.service.gov.uk/components/button/) uses a `<button>` or `<input>` element, use the disabled HTML attribute instead.

You will not need to make any changes if you're using the `govukButton` Nunjucks macro.

Disabling links that are styled to look like buttons will not be supported by future releases.

This was added in [pull request #3326: Deprecate `govuk-button--disabled` class](https://github.com/alphagov/govuk-frontend/pull/3326).

#### Stop using the deprecated Internet Explorer 8 mixins and settings

The next main release of GOV.UK Frontend will remove support for Internet Explorer 8 (IE8). In preparation for this, we've deprecated the settings and mixins used when [generating IE8 specific stylesheets](https://frontend.design-system.service.gov.uk/supporting-ie8/#2-generate-an-ie8-specific-stylesheet).

You'll start seeing deprecation warnings if you're:

- using the [`govuk-if-ie8`](https://frontend.design-system.service.gov.uk/sass-api-reference/#govuk-if-ie8) and [`govuk-not-ie8`](https://frontend.design-system.service.gov.uk/sass-api-reference/#govuk-not-ie8) mixins in your own Sass code (for example `@include govuk-if-ie8`)
- changing the [`$govuk-is-ie8`](https://frontend.design-system.service.gov.uk/sass-api-reference/#govuk-is-ie8) and [`$govuk-ie8-breakpoint`](https://frontend.design-system.service.gov.uk/sass-api-reference/#govuk-ie8-breakpoint) settings to anything other than their default values

If you no longer need to support IE8, we recommend you stop generating an IE8 specific stylesheet and remove references to the IE8 mixins from your code.

You can also silence these deprecation warnings by adding `ie8` to the [`$govuk-suppressed-warnings`](https://frontend.design-system.service.gov.uk/sass-api-reference/#govuk-suppressed-warnings) setting, but once we’ve released v5.0 you will need to address them as part of the upgrade process.

### Fixes

We’ve made fixes to GOV.UK Frontend in the following pull requests:

- [#3255: Including the JavaScript source map in the prototype kit config](https://github.com/alphagov/govuk-frontend/pull/3255)
- [#3272: Add empty alt attribute to logo IE8 fallback PNG](https://github.com/alphagov/govuk-frontend/pull/3272)

- [#3454: Update default link underline offset setting](https://github.com/alphagov/govuk-frontend/pull/3454)

## 4.5.0 (Feature release)

### New features

#### Use summary cards to visually separate multiple summary lists on a single page

You can now use the [summary card](https://design-system.service.gov.uk/components/summary-list#summary-cards). This new variant of the Summary list component can help you:

- design and build pages with multiple summary lists
- show visual dividers between summary lists
- allow users to apply actions to entire lists

This was added in [pull request #2931: Add summary card enhancement to summary list](https://github.com/alphagov/govuk-frontend/pull/2931).

#### Search within accordion content on supporting browsers

We've updated the Accordion component to use the new [`hidden="until-found"` attribute value](https://developer.chrome.com/articles/hidden-until-found/).

This allows the browser's native 'find in page' functionality to search within and automatically open sections of the accordion. Currently, this functionality is only supported by recent versions of Google Chrome, Microsoft Edge and Samsung Internet.

This was added in pull requests:

- [#3053: Enhance the Accordion component with `hidden='until-found'`](https://github.com/alphagov/govuk-frontend/pull/3053)
- [#3095: Hide Accordion content (again) during `.js-enabled` page load](https://github.com/alphagov/govuk-frontend/pull/3095)

#### Source maps for precompiled files

You can now use [source maps](https://firefox-source-docs.mozilla.org/devtools-user/debugger/how_to/use_a_source_map/index.html) to help identify errors and console messages from GOV.UK Frontend precompiled files.

This was added in [pull request #3023: Add source maps to compiled JavaScript and CSS](https://github.com/alphagov/govuk-frontend/pull/3023).

### Fixes

We've fixed errors in IE8 caused by updates to our precompiled JavaScript. The issue prevented some polyfills from running, but was limited to the `release-v4.4.1.zip` and `release-v4.4.0.zip` assets on [GitHub releases](https://github.com/alphagov/govuk-frontend/releases):

- [#3137: Enable UglifyJS compatibility workarounds](https://github.com/alphagov/govuk-frontend/pull/3137)
- [#3013: Swap JavaScript minifier from UglifyJS to terser](https://github.com/alphagov/govuk-frontend/pull/3013)

## 4.4.1 (Fix release)

Note: This release was created from the `support/4.4.x` branch.

### Fixes

We've made fixes to GOV.UK Frontend in the following pull requests:

- [#3087: Fix focus styles for links split over multiple lines in Chromium 108+ (Chrome 108+, Edge 108+, Opera 94+)](https://github.com/alphagov/govuk-frontend/pull/3087)

## 4.4.0 (Feature release)

### New features

#### Change the Button component's background and text colour

For non-GOV.UK branded websites, you can now change the Button component background and text colour.

To change the Button component background colour, set the `$govuk-button-background-colour` Sass variable.

To change the Button component text colour, set the `$govuk-button-text-colour` Sass variable.

```scss
@import "node_modules/govuk-frontend/govuk/base";

$govuk-button-background-colour: govuk-colour("yellow");
$govuk-button-text-colour: govuk-colour("black");
@import "node_modules/govuk-frontend/govuk/components/button/index";
```

This was added in [pull request #2752: Change the Button component background and text colour](https://github.com/alphagov/govuk-frontend/pull/2752). Thanks to [Nick Colley](https://github.com/NickColley) for this contribution.

#### Localise the navigation menu toggle button

When using the [header](https://design-system.service.gov.uk/components/header/) Nunjucks macro, you can now translate the text of the mobile navigation menu toggle button by using the `menuButtonText` parameter.

You should avoid lengthy values for the `menuButtonText` parameter. If the text is too long it can overflow and cause visual issues.

This was added in [pull request #2720: Add parameter to localise mobile menu toggle button](https://github.com/alphagov/govuk-frontend/pull/2720).

#### Localise the character count's textarea description/fallback text

When using the [character count](https://design-system.service.gov.uk/components/character-count/) Nunjucks macro, you can now translate the description of textarea by using the `textareaDescriptionText` option.

This text is announced by screen readers when the character count input is focused. It's also displayed visually as a fallback if JavaScript is not available.

This was added in [pull request #2742: Add ability to customise character count fallback text](https://github.com/alphagov/govuk-frontend/pull/2742), and the option renamed to `textareaDescriptionText` in [pull request #2915](https://github.com/alphagov/govuk-frontend/pull/2915).

#### Localise the character count's counter message

You can now translate the text shown by the [character count](https://design-system.service.gov.uk/components/character-count/) component to inform users of:

- when they have reached the maximum number of characters or words
- the number of characters or words over or under the allowed maximum

The Nunjucks macro accepts new options so you can customise each message. You can:

- Use `charactersAtLimitText` or `wordsAtLimitText` to provide the text that shows when users have reached the limit.
- Use `charactersUnderLimitText` or `wordsUnderLimitText` to provide the text that shows when users are under the limit. The component will pluralise the message according to the configured locale and the number of characters or words remaining.
- Use `charactersOverLimitText` or `wordsOverLimitText` to provide the text that shows when users are over the limit. The component will pluralise the message according to the configured locale and the number of characters or words remaining.

You'll find guidance about [the plural forms in our documentation about localising GOV.UK Frontend](https://frontend.design-system.service.gov.uk/localise-govuk-frontend/). The component will replace `%{count}` with the number of characters over or under the limit.

If you're not using Nunjucks macros, you can use data-\* attributes to provide these translations. Within the attribute value, any [quotation marks or other characters reserved by HTML](https://developer.mozilla.org/en-US/docs/Glossary/Entity#reserved_characters) needs to be converted into their HTML entity equivalents.

You can:

- use `data-i18n.characters-at-limit` or `data-i18n.words-at-limit` for when users are at the limit
- configure the text that informs the end user they are under the character or word limit, by using `data-i18n.characters-under-limit.{other,many,few,two,one,zero}` or `data-i18n.words-under-limit.{other,many,few,two,one,zero}`, with one suffix for each plural form required by your locale
- configure the text that informs the end user they are over the character or word limit, by using `data-i18n.characters-over-limit.{other,many,few,two,one,zero}` or `data-i18n.words-over-limit.{other,many,few,two,one,zero}`, with one suffix for each plural form required by your locale

You can also provide these messages using a JavaScript configuration object when creating an instance of the component or initialising all components. See [our guidance on localising GOV.UK Frontend](https://frontend.design-system.service.gov.uk/localise-govuk-frontend/) for how to do this.

This was added in the following pull requests:

- [#2895 Add macro options to configure CharacterCount translations](https://github.com/alphagov/govuk-frontend/pull/2895)
- [#2887 Allow CharacterCount component to receive i18n config via JS](https://github.com/alphagov/govuk-frontend/pull/2887)

#### Localise the character count's input description for assistive technologies

When configuring the character count's limit in JavaScript, you can customise the description provided to assistive technologies when users focus the input (so it indicates the overall limit of characters or words).

Depending on the [plural form required by your locale](https://frontend.design-system.service.gov.uk/localise-govuk-frontend/#understanding-pluralisation-rules), you can pass the description in the HTML using the `data-i18n.textarea-description.{other,many,few,two,one,zero}` attribute on the element to provide the text to set as the description.

This was added in [pull request #2915](https://github.com/alphagov/govuk-frontend/pull/2915).

#### Localise the accordion's toggle buttons

You can now translate the text of the [accordion](https://design-system.service.gov.uk/components/accordion/) component's show and hide toggle buttons.

When using the Nunjucks macro, you can use the new `showSectionText` and `hideSectionText` parameters to customise the text of the 'show' and 'hide' toggles in each section.

You can also use `showAllSectionsText` and `hideAllSectionsText` parameters to customise the text of the toggle at the top of the accordion.

If you're not using the Nunjucks macro, you can customise these using data-\* attributes. Within the attribute value, any [quotation marks or other characters reserved by HTML](https://developer.mozilla.org/en-US/docs/Glossary/Entity#reserved_characters) needs to be converted into their HTML entity equivalents.

- `data-i18n.show-section`
- `data-i18n.show-section-aria-label`
- `data-i18n.hide-section`
- `data-i18n.hide-section-aria-label`
- `data-i18n.show-all-sections`
- `data-i18n.hide-all-sections`

You can also change this text for all instances of the Accordion using a JavaScript configuration object. See [our guidance on localising GOV.UK Frontend](https://frontend.design-system.service.gov.uk/localise-govuk-frontend/) for how to do this.

This was added in pull requests:

- [#2818: Add support for localisation via data-\* attributes to Accordion component](https://github.com/alphagov/govuk-frontend/pull/2818)
- [#2826: Add support for localisation via JavaScript configuration to Accordion component](https://github.com/alphagov/govuk-frontend/pull/2826)

#### Suppress deprecation warnings

You can now suppress warnings from deprecations within GOV.UK Frontend by updating the `$govuk-suppressed-warnings` map in Sass. Every deprecation warning will now include a warning "key" which you can use in the following code, placed at the root of your sass project:

```scss
$govuk-suppressed-warnings: (
  deprecated-feature
);
```

This was added in [#2911 Add warning suppression functionality](https://github.com/alphagov/govuk-frontend/pull/2911)

#### Configure components in JavaScript

JavaScript components can get the same configuration options in 2 ways - through data attributes, as before, and now when creating an instance. These components are:

- the `Button` component, for its `preventDoubleClick` option (matching `data-prevent-double-click`)
- the `CharacterCount` component, for its `maxlength`, `maxwords` and `threshold` options (matching `data-maxlength`, `data-maxwords` and `data-threshold`, respectively)
- the `ErrorSummary` component, for its `disableAutoFocus` option (matching `data-disable-auto-focus`)
- the `NotificationBanner` component, for its `disableAutoFocus` option (matching `data-disable-auto-focus`)

You can leave out these configuration options when using the Nunjucks macro and provide configuration when:

- creating a component, in a configuration object as second argument
- initialising components in bulk using `initAll`

For example:

```js
// Creating a single instance
var button = document.querySelector('[data-module="button"]')
new GOVUKFrontend.Button(button, {preventDoubleClick: true})

// Or initialising components in bulk
GOVUKFrontend.initAll({
  button: {
    preventDoubleClick: true
  }
  // Or, for the other components,
  // characterCount: {/* options */},
  // errorSummary: {/* options */},
  // notificationBanner: {/* options */}
})
```

You can find more information about component configuration in [GOV.UK Frontend documentation](https://frontend.design-system.service.gov.uk/configure-components-with-javascript/).

This was added in pull requests specific for each components:

- [NotificationBanner – #2843](https://github.com/alphagov/govuk-frontend/pull/2843)
- [ErrorSummary – #2854](https://github.com/alphagov/govuk-frontend/pull/2854)
- [Button – #2867](https://github.com/alphagov/govuk-frontend/pull/2867)
- [CharacterCount – #2883](https://github.com/alphagov/govuk-frontend/pull/2883)

### Recommended changes

#### Update the HTML for the error summary

If you're not using the Nunjucks macros, you can improve the experience for screen reader users by making these changes to the error summary markup:

- Remove `aria-labelledby="error-summary-title"` and `role="alert"` from the parent element (`govuk-error-summary`)
- Add a `div` wrapper around the contents of `govuk-error-summary` with the attribute `role="alert"`
- Remove `id="error-summary-title"` from the error summary `h2` (`govuk-error-summary__title`)

This will enable screen reader users to have a better, more coherent experience with the error summary. It will make sure users of JAWS 2022 or later will hear the entire contents of the error summary on page load and therefore have further context on why there is an error on the page they're on.

This was added in [pull request #2677: Amend error summary markup to fix page load focus bug in JAWS 2022](https://github.com/alphagov/govuk-frontend/pull/2677).

### Deprecated features

#### Stop using the compatibility mode settings

In GOV.UK Frontend v5.0 we will stop supporting compatibility with legacy codebases. We are therefore deprecating the compatibility mode variables associated with legacy codebases:

- `$govuk-compatibility-govukfrontendtoolkit`
- `$govuk-compatibility-govuktemplate`
- `$govuk-compatibility-govukelements`

This was introduced in [pull request #2882: Deprecate compatibility mode settings](https://github.com/alphagov/govuk-frontend/pull/2882).

#### Stop using settings associated with legacy codebases

In GOV.UK Frontend v5.0 we will stop supporting compatibility with legacy codebases. As part of this, we're deprecating settings controlled by compatibility mode variables. This includes the `govuk-compatibility` mixin and the following settings:

- `$govuk-use-legacy-palette`
- `$govuk-use-legacy-font`
- `$govuk-typography-use-rem`
- `$govuk-font-family-tabular`

This was introduced in [pull request #2844: Remove compatibility mode from govuk-frontend](https://github.com/alphagov/govuk-frontend/pull/2844).

### Fixes

In [pull request 2851: Support Prototype Kit v13](https://github.com/alphagov/govuk-frontend/pull/2851) we've introduced support for the plugins system included in the upcoming Prototype Kit v13.

We've made fixes to GOV.UK Frontend in the following pull requests:

- [#2807: Tidy up and refactor the Character Count JavaScript](https://github.com/alphagov/govuk-frontend/pull/2807)
- [#2811: Use Element.id to get module id for accordion](https://github.com/alphagov/govuk-frontend/pull/2811)
- [#2821: Avoid duplicated --error class on Character Count](https://github.com/alphagov/govuk-frontend/pull/2821)
- [#2800: Improve Pagination component print styles](https://github.com/alphagov/govuk-frontend/pull/2800)
- [#2909: Fix JavaScript errors when entering text into the Character Count in IE8](https://github.com/alphagov/govuk-frontend/pull/2909)

## 4.3.1 (Patch release)

### Recommended changes

#### Replace deprecated `govuk-!-margin-static` and `govuk-!-padding-static` classes

We've fixed an error in the naming convention of the static spacing override classes we'd introduced in v4.3.0. These classes should start with `govuk-!-static`, and we've now deprecated the incorrect classes.

If you're using the static spacing margin override classes, replace any classes starting with `govuk-!-margin-static` with `govuk-!-static-margin`. For example: `govuk-!-margin-static-2` would become `govuk-!-static-margin-2`.

If you're using the static spacing padding override classes, replace any classes starting with `govuk-!-padding-static` with `govuk-!-static-padding`. For example: `govuk-!-padding-static-2` would become `govuk-!-static-padding-2`.

We've deprecated the `govuk-!-margin-static` and `govuk-!-padding-static` classes, and will remove them in a future major release.

This change was introduced in [pull request #2770: Fix ordering of properties in static spacing override classes](https://github.com/alphagov/govuk-frontend/pull/2770). Thanks to @garrystewart for reporting this issue.

### Fixes

We’ve made fixes to GOV.UK Frontend in the following pull requests:

- [#2766: Remove unused `console.log` calls from accordion JavaScript](https://github.com/alphagov/govuk-frontend/pull/2766)

## 4.3.0 (Feature release)

### New features

#### Customise the Open Graph image URL without duplicate meta tags

You can now customise the Open Graph image URL included in the `head` by setting the `opengraphImageUrl` Nunjucks option.

Also, the default Open Graph image URL meta tag will now only be included if you set the either `opengraphImageUrl` or `assetUrl`.

This was added in [pull request #2673: Allow Open Graph image URL to be customised](https://github.com/alphagov/govuk-frontend/pull/2673).

#### Localise the content licence and copyright statements

When using the [footer Nunjucks macro](https://design-system.service.gov.uk/components/footer/#options-default-1), you can now translate the text of the Open Government Licence (OGL) and Crown copyright statements using the `contentLicence` and `copyright` parameters.

Visit [The National Archives' documentation on OGL and Crown copyright](https://www.nationalarchives.gov.uk/information-management/re-using-public-sector-information/uk-government-licensing-framework/open-government-licence/copyright-notices-attribution-statements/) for information on what you need to include in these statements.

This was added in [pull request #2702: Allow localisation of content licence and copyright notices in Footer](https://github.com/alphagov/govuk-frontend/pull/2702).

#### Pass HTML directly into compatible components

If using the Nunjucks macros, you can now pass HTML content directly into compatible components using [the Nunjucks call syntax](https://mozilla.github.io/nunjucks/templating.html#call). If HTML is provided through the call syntax, the nunjucks macro will ignore the HTML and text options.

Components updated to support this syntax are:

- Details
- Error summary (mapped to `descriptionHtml` parameter)
- Inset text
- Notification banner
- Panel

This was added in [pull request #2734: Update various components to be callable](https://github.com/alphagov/govuk-frontend/pull/2734).

#### Use new override classes to apply static spacing

You can now use static spacing override classes to apply spacing from [the static spacing scale](https://design-system.service.gov.uk/styles/spacing/#static-spacing) to elements of your design.

The new classes start with: `govuk-!-static-` followed by either `margin-` or `padding-`, and then a spacing unit number.

To apply spacing in a single direction, include `left-`, `right-`, `top-`, or `bottom-` just before the spacing unit.

For example:

- `govuk-!-static-margin-9` will apply a 60px margin to all sides of the element at all screen sizes
- `govuk-!-static-padding-right-5` will apply 25px of padding to the right side of the element at all screen sizes
- `govuk-!-static-margin-0` will remove all margins at all screen sizes

This was added in [pull request #2672: Add static spacing override classes](https://github.com/alphagov/govuk-frontend/pull/2672). Thanks to @patrickpatrickpatrick for this contribution.

### Deprecated features

#### Remove deprecated `govuk-header__navigation--no-service-name` class in the header

We've deprecated the `govuk-header__navigation--no-service-name` class, and will remove it in a future major release.

This was added in [pull request #2694: Deprecate .govuk-header\_\_navigation--no-service-name](https://github.com/alphagov/govuk-frontend/pull/2694).

### Recommended changes

We've recently made some non-breaking changes to GOV.UK Frontend. Implementing these changes will make your service work better.

#### Add `hidden` to the mobile menu button in the header component

If you're not using the Nunjucks macros, add the `hidden` attribute to the mobile menu button in the header component. The mobile menu button is `govuk-header__menu-button`.

We've changed the header's mobile menu functionality to use the `hidden` attribute instead of using CSS to show/hide the mobile menu. Adding `hidden` to the mobile menu button by default will make sure that it does not display for users when javascript does not load.

This was added in [pull request 2727: Make use of hidden in header navigation functionality](https://github.com/alphagov/govuk-frontend/pull/2727). Thanks to @NickColley and @kr8n3r for their contributions.

### Fixes

In [pull request 2678: Replace ex units with ems for input lengths](https://github.com/alphagov/govuk-frontend/pull/2678), we changed how we define input lengths in our CSS. Browsers might now display these inputs as being slightly wider than before. The difference is usually fewer than 3 pixels.

We’ve also made fixes in the following pull requests:

- [#2668: Fix Summary List action link alignment](https://github.com/alphagov/govuk-frontend/pull/2668)
- [#2670: Define minimum width for select component](https://github.com/alphagov/govuk-frontend/pull/2670) - thanks @Nosfistis for reporting this issue
- [#2723: Style accordion and tabs text content with govuk-body class](https://github.com/alphagov/govuk-frontend/pull/2723)
- [#2724: Remove redundant aria-hidden attribute from the content when using the Details polyfill](https://github.com/alphagov/govuk-frontend/pull/2724)
- [#2725: Remove padding-right from last column in summary list row](https://github.com/alphagov/govuk-frontend/pull/2725) - thanks @edwardhorsford for reporting this issue and suggesting a fix
- [#2737: Avoid unnecessary spacing-related media queries](https://github.com/alphagov/govuk-frontend/pull/2737)
- [#2747: Ensure accordion uses overriden focus colour](https://github.com/alphagov/govuk-frontend/pull/2747) - thanks @NickColley for reporting this issue and suggesting a fix

## 4.2.0 (Feature release)

### New features

#### Help users navigate through pages with pagination

You can now use [pagination](https://design-system.service.gov.uk/components/pagination/) to help users navigate forwards and backwards through a series of pages. For example, in search results or guidance that's divided into multiple website pages.

This was added in [pull request #2610: Add pagination component](https://github.com/alphagov/govuk-frontend/pull/2610).

#### Check checkboxes by using the `values` Nunjucks option

When using the `govukCheckboxes` Nunjucks macro, you can now use the `values` option to determine which checkboxes should already be checked when the page loads.

For example, `values: ['red', 'blue']` would check any checkboxes that have a `value` of 'red' or 'blue'.

You can use this option instead of setting the boolean `checked` option on each individual checkbox.

This change was introduced in [pull request #2616: Allow selecting options by passing current values](https://github.com/alphagov/govuk-frontend/pull/2616).

#### Check a radio button by using the `value` Nunjucks option

When using the `govukRadios` Nunjucks macro, you can now use the `value` option to determine which radio should already be checked when the page loads.

For example, `value: 'red'` would check the radio that has a `value` of 'red'.

You can use this option instead of setting the boolean `checked` option on each individual radio.

This change was introduced in [pull request #2616: Allow selecting options by passing current values](https://github.com/alphagov/govuk-frontend/pull/2616).

#### Select an option in a select by using the `value` Nunjucks option

When using the `govukSelect` Nunjucks macro, you can now use the `value` option to determine which option should already be selected when the page loads.

For example, `value: 'red'` would select the option that has a `value` of 'red'.

You can use this option instead of setting the boolean `selected` option on each individual option.

This change was introduced in [pull request #2616: Allow selecting options by passing current values](https://github.com/alphagov/govuk-frontend/pull/2616).

### Recommended changes

#### Replace deprecated `govuk-header__link--service-name` class in the header

If you're not using the Nunjucks macros in the header, replace any instances of the class `govuk-header__link--service-name` with `govuk-header__service-name`.

We've deprecated the `govuk-header__link--service-name` class, and will remove it in a future major release.

This change was introduced in [pull request #2617: Do not make the service name in the header a link if no `serviceUrl` is provided](https://github.com/alphagov/govuk-frontend/pull/2617).

#### File extensions added for JavaScript ES Module imports

We have updated our component ES module JavaScript to include [missing file extensions](https://nodejs.org/api/esm.html#mandatory-file-extensions) not provided in release 4.1.0. If you have received an error similar to the following, for example when running or building your application, this fix should resolve the issue.

```
Cannot find module '../node_modules/govuk-frontend/govuk-esm/common' imported from ../node_modules/govuk-frontend/govuk-esm/all.mjs
```

You should not need to make any changes if you are successfully importing our JavaScript as ES modules with version 4.1.0, but there still might be config you can remove. For example, removing `fullySpecified: false` from your Webpack config file.

This change was introduced in [pull request #2658: Add missing mandatory file extensions for ESM JavaScript](https://github.com/alphagov/govuk-frontend/pull/2658). Thanks to @colinrotherham and @tvararu for reporting issues and suggesting and testing fixes.

### Fixes

We’ve made fixes to GOV.UK Frontend in the following pull requests:

- [#2617: Do not make the service name in the header a link if no `serviceUrl` is provided](https://github.com/alphagov/govuk-frontend/pull/2617)
- [#2640: Add top padding to accordion section](https://github.com/alphagov/govuk-frontend/pull/2640)
- [#2644: Allow users to use `require.resolve` to import GOV.UK Frontend JavaScript](https://github.com/alphagov/govuk-frontend/pull/2644) - thanks to @HughePaul for reporting this issue and testing the fix

- [#2659: Add missing label and legend classes to HTML fixtures](https://github.com/alphagov/govuk-frontend/pull/2659)

## 4.1.0 (Feature release)

### New features

#### Import GOV.UK Frontend JavaScript as ECMAScript (ES) modules

You can now import our component JavaScript into your service as ES modules, if you're using a bundler.

This change allows you to import only the JavaScript you need, and helps reduce duplication of polyfills.

Because we're shipping ES modules in addition to how we currently publish our component JavaScript, this change is backwards compatible. You will not be required to make any changes unless you want to.

If you want to import using ES modules, we recommend you only use `import` to import the JavaScript for components you're using in your service. For example:

```javascript
import { SkipLink, Radios } from 'govuk-frontend'

var $skipLink = document.querySelector('[data-module="govuk-skip-link"]')
if ($skipLink) {
  new SkipLink($skipLink).init()
}

var $radios = document.querySelectorAll('[data-module="govuk-radios]')
if ($radios) {
  for (var i = 0; i < $radios.length; i++) {
    new Radios($radios[i]).init()
  }
}
```

If you need to import all of GOV.UK Frontend's components, then use the `initAll` function to initialise them:

```javascript
import { initAll } from 'govuk-frontend'
initAll()
```

Depending on the bundler you use, you may also need to make changes to your JavaScript bundler configuration file. You can [read more in our installation instructions about importing JavaScript using a bundler](https://frontend.design-system.service.gov.uk/importing-css-assets-and-javascript/#import-javascript-using-a-bundler).

This was added in [pull request #2586: Publish our JavaScript as ES modules alongside Universal Module Definition (UMD)](https://github.com/alphagov/govuk-frontend/pull/2586).

### Recommended changes

We've recently made some non-breaking changes to GOV.UK Frontend. Implementing these changes will make your service work better.

#### Remove `aria-live` from the character count component

If you're not using the Nunjucks macros, remove the `aria-live` attribute from the character count message element. This element's content no longer updates, as we've moved the live counter functionality to a new element injected by JavaScript.

This change was introduced in [pull request #2577: Refactor character count to inject new element](https://github.com/alphagov/govuk-frontend/pull/2577).

#### Remove `pattern` from the date input component

If you're not using the Nunjucks macros, remove `pattern="[0-9]*"` from each of the date input's elements.

We originally added the `pattern` attribute to make numeric keypad functionality the default functionality in Safari on iOS. However, we no longer need to use it, as the `inputmode` attribute provides this functionality for newer Safari versions.

This change was introduced in [pull request #2599: Remove `pattern` attribute from date input component](https://github.com/alphagov/govuk-frontend/pull/2599).

### Fixes

We've made the following fixes in [pull request #2577: Refactor character count to inject new element](https://github.com/alphagov/govuk-frontend/pull/2577):

- fix character count message being repeated twice by screen readers
- fix character count hint text being announced as part of the count message
- fix multiple outdated character count messages being announced at once
- fix character count message being announced when input length is below a defined threshold

We’ve also made fixes in the following pull requests:

- [#2549: Fix header with product name focus and hover state length](https://github.com/alphagov/govuk-frontend/pull/2549)
- [#2573: Better handle cases where `$govuk-text-colour` is set to a non-colour value](https://github.com/alphagov/govuk-frontend/pull/2573)
- [#2590: Remove `maxlength` attribute from `textarea` after character count JavaScript has been initialised](https://github.com/alphagov/govuk-frontend/pull/2590)
- [#2615: Fix hints for disabled checkboxes or radios appearing darker than the associated labels](https://github.com/alphagov/govuk-frontend/pull/2615)

## 4.0.1 (Fix release)

### Recommended changes

We've recently made some non-breaking changes to GOV.UK Frontend. Implementing these changes will make your service work better.

#### Remove the `tabindex` attribute from the error summary component

If you're not using Nunjucks macros, remove the `tabindex` attribute from the error summary's HTML. The component JavaScript now adds and removes this attribute.

This change was introduced in [pull request #2491: Prevent error summary from being refocused after it has been initially focused on page load](https://github.com/alphagov/govuk-frontend/pull/2491).

### Fixes

We’ve made fixes to GOV.UK Frontend in the following pull requests:

- [#2475: Tweak whitespace HTML for text input component to improve readability](https://github.com/alphagov/govuk-frontend/pull/2475)
- [#2494: Allow disabling autofocus on error summary](https://github.com/alphagov/govuk-frontend/pull/2494)
- [#2514: Fix accordion heading style while JavaScript is disabled](https://github.com/alphagov/govuk-frontend/pull/2514)
- [#2515: Add explicit width to summary list row with 'no actions' pseudo-element](https://github.com/alphagov/govuk-frontend/pull/2515)
- [#2524: Fix select component renders with grey background in Firefox and Safari](https://github.com/alphagov/govuk-frontend/pull/2524)

## 4.0.0 (Breaking release)

### Breaking changes

This release contains a lot of breaking changes, but we expect many of them will only affect a small number of users. However, to make sure your service still works after you upgrade, you should read the release notes and make any required changes.

#### Check your accordions still display as expected

We've changed the design of the accordion. You can [see its new look and read the revised guidance, particularly about when and when not to use accordions](https://design-system.service.gov.uk/components/accordion/).

You should check your accordions still display as expected if you have any:

- accordions with custom styles
- section headings that contain unusual formatting (for example, wrappers)

You do not need to make changes to the content that accordions hide or show, as this release's changes do not affect it.

These changes were introduced in [pull request #2257: Update accordion design](https://github.com/alphagov/govuk-frontend/pull/2257). Thanks to [Mia Allers](https://github.com/mia-allers-gds), [Owen Jones](https://github.com/owenatgov), [Nikin Nagewadia](https://github.com/nnagewad) and [Chris Yoong](https://github.com/chris-gds) for their contributions.

#### Only use the accordion’s summary line for ‘phrasing content’

The summary line is now inside the HTML `button` element, so you can only add ['phrasing content'](https://www.w3.org/TR/2011/WD-html5-20110525/content-models.html#phrasing-content-0) to it. Do not use any non-phrasing content, as the resulting HTML will not be valid.

This change was introduced in [pull request #2257: Update accordion design](https://github.com/alphagov/govuk-frontend/pull/2257).

#### Review and revise the accordion's summary line content

Only add a summary line if you need to, as it's likely to make the button text too long.

If you're already using the summary line, review your use of the summary line to make sure you actually need it.

If you need to keep the summary line, [review the accordion guidance](https://design-system.service.gov.uk/components/accordion/) and make the summary line as short as possible.

#### Update the HTML for summary lists

We've updated the HTML for the summary list component to avoid nesting `<span>` elements within `<dd>` elements, which is invalid HTML. This update only affects you if you have summary lists that include a mix of rows with and without actions. You can [read more about adding actions to rows](https://design-system.service.gov.uk/components/summary-list/#adding-actions-to-each-row).

If you're not using Nunjucks macros, do not include an empty `<span class="govuk-summary-list__actions"></span>` in rows without actions. Instead, add the `govuk-summary-list__row--no-actions` modifier class to the row.

This change was introduced in [pull request #2323: Avoid invalid nesting of `<span>` within a `<dd>` in summary list](https://github.com/alphagov/govuk-frontend/pull/2323). Thanks to [Malcolm Hire](https://github.com/malcolmhire) for reporting this issue.

#### Update the HTML for navigation in the header

We've updated the HTML for the header. This update only affects you if your header includes navigation.

Any additional classes passed using the `navigationClasses` Nunjucks option are now applied to the `<nav>` rather than the `<ul>`. Check the additional classes are still doing what you expect.

If you're not using Nunjucks macros, then you should:

- move the `<button>` inside the `<nav>`, immediately before the `<ul>`
- move the `aria-label` attribute from the `<ul>` to the `<nav>`
- move the `govuk-header__navigation` class from the `<ul>` to the `<nav>`
- add the `govuk-header__navigation-list` class to the `<ul>`

[Check your changes against the header example in the Design System](https://design-system.service.gov.uk/components/header/#header-with-service-name-and-navigation) to make sure you have correctly implemented them.

This change was introduced in [pull request #2427: Improve the screen reader experience for the header menu](https://github.com/alphagov/govuk-frontend/pull/2427).

#### Style any custom HTML in your cookie banner

We've removed the default font styles from the cookie banner Sass. This change makes it more obvious when you have not added classes and styles to any custom HTML.

If you're passing custom HTML into the cookie banner component (for example, using the `html` Nunjucks parameter), you must make sure you're applying the appropriate classes and styles to that HTML. This could look like, for example, adding the `govuk-body` class to any paragraph tags. You must do this to prevent your cookie banner displaying with unstyled text.

This change was introduced in [pull request #2432: Remove default font styles from cookie banner Sass](https://github.com/alphagov/govuk-frontend/pull/2432).

#### Update the HTML for hints

In GOV.UK Frontend v3.8.0, we [updated the HTML for hints to use a `<div>` rather than a `<span>` element, to allow the use of block elements](https://github.com/alphagov/govuk-frontend/issues/1835). We've now removed the styles which made the hint `<span>` display as block.

If you’re not using Nunjucks macros, update your hint HTML to use a `<div>` rather than a `<span>`. For example: `<div id="input-hint" class="govuk-hint"></div>` instead of `<span id="input-hint" class="govuk-hint"></span>`.

This change was introduced in [pull request #2437: Remove `display:block` on hint component](https://github.com/alphagov/govuk-frontend/pull/2437).

#### Include JavaScript for skip link to improve screen reader announcements

We've added JavaScript for the skip link component to set focus to the linked element, for example, the main content on the page. This helps screen readers read the linked content when users use the skip link component.

If you're [importing JavaScript for individual components](https://frontend.design-system.service.gov.uk/importing-css-assets-and-javascript/#select-and-initialise-an-individual-component), import the skip link JavaScript.

If you're not using Nunjucks macros, add a `data-module="govuk-skip-link"` attribute to the component HTML. For example:

```html
<div class="govuk-skip-link" data-module="govuk-skip-link">
...
</div>
```

Once you've made the changes, check the skip link JavaScript works. To do this, select the skip link and check the linked element (usually the `<main>` element) in the browser has a `tabindex` attribute.

This change was introduced in [pull request #2450: Set focus to skip link target to improve screen reader announcements](https://github.com/alphagov/govuk-frontend/pull/2450).

#### Update the HTML for error messages

We’ve updated the HTML for the error message component to use a `<p>` element instead of a `<span>` element, as this is more semantically correct.

If you’re not using Nunjucks macros, swap the `<span class="govuk-error-message">` for a `<p class="govuk-error-message">`.

This change was introduced in [pull request #2452: Update error messages to use paragraph tags instead of spans](https://github.com/alphagov/govuk-frontend/pull/2452).

#### Check components that conditionally reveal content still work

On radios and checkboxes, the JavaScript now looks within the whole page for conditionally-revealed content. Before, it only looked within the same set of radios or checkboxes.

If you see unexpected behaviour, [make sure the revealed content's `id` is unique within the page the content is on](https://www.w3.org/WAI/WCAG21/Techniques/html/H93). Reusing the same `id` within a page could cause a radio or checkbox to reveal or hide the wrong element, and also means your HTML is invalid.

This change was introduced in [pull request #2370: Prevent issues with conditionally revealed content when content `id` includes CSS syntax characters](https://github.com/alphagov/govuk-frontend/pull/2370).

#### Check the character count component still works as expected

On character counts, the JavaScript now looks within the whole page for the count message, which will be something similar to “You have 200 characters remaining”. Before, it only looked within the character count component.

If you see unexpected behaviour, make sure the `id` for the textarea component is unique within the page the content is on. Reusing the same `id` within a page could cause the wrong count message to update, and also means your HTML is invalid.

This change was introduced in [pull request #2408: Prevent issues with character count when textarea `id` includes CSS syntax characters](https://github.com/alphagov/govuk-frontend/pull/2408).

#### Check individually-imported JavaScript modules work as expected

You do not need to do anything if you have done at least one of the following:

- followed our [Getting Started guide](https://frontend.design-system.service.gov.uk/get-started/#5-get-the-javascript-working) and are importing all of the GOV.UK Frontend JavaScript in one go via `all.js`
- installed GOV.UK Frontend using precompiled files

We've changed the naming of our components' JavaScript modules so individual imports are now attached to
`window.GOVUKFrontend.[ComponentName]` instead of `window.GOVUKFrontend`.

You can now import multiple modules without overwriting the previous one, for example:

```
//= require govuk/components/accordion/accordion.js
//= require govuk/components/button/button.js

# These modules are available under window.GOVUKFrontend.Accordion and window.GOVUKFrontend.Button respectively
```

If you're importing JavaScript modules individually, you should check any references to `window.GOVUKFrontend` in your code and update them to point to the correct component, `window.GOVUKFrontend.[ComponentName]`. You can now remove any workarounds you may have implemented.

This change was introduced in [pull request #2426: Rename exported JavaScript modules to include component name](https://github.com/alphagov/govuk-frontend/pull/2426). Thanks to [Alex Jurubita](https://github.com/alex-ju) for reporting this issue.

#### Import 'base' before importing Sass files from `core` or `overrides` layers

If you import individual files from the `core` or `overrides` layers, you might see the error `Undefined mixin 'govuk-exports'` or `no mixin named govuk-exports` when compiling your Sass.

To fix the error, import `node_modules/govuk-frontend/govuk/base` first. For example:

```scss
@import "node_modules/govuk-frontend/govuk/base";
@import "node_modules/govuk-frontend/core/typography";
```

This change was introduced in [pull request #2455: Remove 'base' import from files in `core` and `overrides` layers](https://github.com/alphagov/govuk-frontend/pull/2455).

#### Import 'template' Sass file from the `objects` layer instead of the `core` layer

If you import the 'template' Sass file from the `core` layer, you might see the error `File to import not found or unreadable: template` when compiling your Sass.

To fix this error, replace any imports of `node_modules/govuk-frontend/govuk/core/template` with `node_modules/govuk-frontend/govuk/objects/template`.

This change was introduced in [pull request #2463: Move template styles from `core` to `objects` layer](https://github.com/alphagov/govuk-frontend/pull/2463).

#### Check your footer displays as expected

We’ve made some fixes to the alignment of columns within the footer component, so they now align with our grid. We've also removed the logic that assumes a 2-section layout displays as a 'two-thirds and one-third' layout. Footer sections now display as full-width by default.

If you're using the Nunjucks macros, check your footer displays as expected and use the `width` macro option to set the width you want for each section.

If you're not using the Nunjucks macros, check your footer displays as expected and use the standard Design System grid classes on the `govuk-footer__section` element to set the width. For example:

```html
<div class="govuk-footer__section govuk-grid-column-two-thirds">...</div>
```

This change was introduced in [pull request #2462: Fix footer alignment with grid classes and add `width` macro option](https://github.com/alphagov/govuk-frontend/pull/2462).

#### Remove deprecated `$govuk-border-width-form-element-error` variable

In [GOV.UK Frontend v3.8.0](https://github.com/alphagov/govuk-frontend/releases/tag/v3.8.0), we made the border width of form elements in their error state the same as for form elements in their normal state and deprecated the `$govuk-border-width-form-element-error` variable.

Before, an element's border got thicker to show the element was in an error state. However, elements in their focused state also have a thicker border. As a result, when users focused an element in an error state, the only visible border-change was from red to black. Not all users could perceive this change. So, we reduced the element border's width, to make sure its thickness changes when users focus.

We've now removed `$govuk-border-width-form-element-error` completely.

If you’re referencing `$govuk-border-width-form-element-error` in your own Sass, you must remove it. If you're also defining your own error state, you only need to change the border colour.

You should avoid overriding the border width. For example, replace `border: $govuk-border-width-form-element-error solid $govuk-error-colour;` with `border-color: $govuk-error-colour;`.

You should also remove any override of `$govuk-border-width-form-element-error` from your Sass. This override no longer does anything.

This change was introduced in [pull request #1963: Remove deprecated `$govuk-border-width-form-element-error` variable](https://github.com/alphagov/govuk-frontend/pull/1963).

#### Remove deprecated `govuk-main-wrapper` and `govuk-main-wrapper--l` mixins

We've removed the `govuk-main-wrapper` and `govuk-main-wrapper--l` mixins we deprecated in [GOV.UK Frontend v3.0.0](https://github.com/alphagov/govuk-frontend/releases/tag/v3.0.0).

Remove any use of these mixins in your own Sass. You can replace these mixins with direct references to the [spacing mixins](https://design-system.service.gov.uk/styles/spacing/#spacing-on-custom-components).

This change was introduced in [pull request #2385: Remove deprecated `govuk-main-wrapper` and `govuk-main-wrapper--l` mixins](https://github.com/alphagov/govuk-frontend/pull/2385).

#### Remove calls to deprecated `iff` Sass function

We've removed the `iff` function we deprecated in [GOV.UK Frontend version 3.6.0](https://github.com/alphagov/govuk-frontend/releases/tag/v3.6.0).

If you’re calling `iff` from your own Sass, you should use [Sass's native `if` function](https://sass-lang.com/documentation/modules#if) instead.

This change was introduced in [pull request #2409: Remove deprecated `iff` Sass function](https://github.com/alphagov/govuk-frontend/pull/2409).

#### Remove deprecated `govuk-tag--inactive` class

We've removed the `govuk-tag--inactive` class we deprecated in [GOV.UK Frontend v3.6.0](https://github.com/alphagov/govuk-frontend/releases/tag/v3.6.0).

Replace any use of this class with the `govuk-tag--grey` class.

This change was introduced in [pull request #2417: Remove deprecated `govuk-tag--inactive class`](https://github.com/alphagov/govuk-frontend/pull/2417).

### Recommended changes

We've recently made some other changes to GOV.UK Frontend. While these are not breaking changes, implementing them will make your service work better.

You do not need to do anything if you're using Nunjucks macros.

#### Change date input from `type="number"` to `inputmode="numeric"`

There are some known issues with inputs of `type="number"`. [Read our research into the issues with `type="number"`.](https://github.com/alphagov/govuk-frontend/issues/1449#issuecomment-503186819)

If you’re not using Nunjucks macros, remove the `type="number"` attribute from the date input component.

Replace it with `type="text"` and `inputmode="numeric"`. For example:

```
<input class="govuk-input govuk-date-input__input" id="passport-issued-month" name="passport-issued-month" type="text" pattern="[0-9]*" inputmode="numeric">

```

This change was introduced in [pull request #1704: Update date input to use `type=text` and `inputmode=numeric`](https://github.com/alphagov/govuk-frontend/pull/1704).

#### Fix fallback logo so Chrome will not flag it to screen readers

If you’re not using Nunjucks macros, change the SVG markup within the header, footer and button components. We’ve added this fix so screen readers will not announce the fallback image to users.

For the header, footer and button, replace `role="presentation"` with `aria-hidden="true"`. For example:

```
<svg class="govuk-button__start-icon" xmlns="http://www.w3.org/2000/svg" width="17.5" height="19" viewBox="0 0 33 40" aria-hidden="true" focusable="false">
```

This change was introduced in [pull request #1724: Fix fallback logo so Chrome will not flag it to screen readers](https://github.com/alphagov/govuk-frontend/pull/1724).

#### Add `data-nosnippet` attribute to cookie banner

Apply a `data-nosnippet` attribute to the cookie banner component to stop it appearing in Google Search snippets.

If you’re not using Nunjucks macros, add a new `data-nosnippet` attribute to the cookie banner.

```
<div class="govuk-cookie-banner " data-nosnippet role="region" aria-label="Cookies on your service">
```

This change was introduced in [pull request #2192: Add `data-nosnippet` to prevent cookie banner text appearing in Google Search snippets](https://github.com/alphagov/govuk-frontend/pull/2192).

## 3.14.0 (Feature release)

Note: This release was created from the `support/3.x` branch.

### New features

#### Set text alignment with override classes

You can now use the `govuk-!-text-align-left`, `govuk-!-text-align-centre` and `govuk-!-text-align-right` CSS classes to set text alignment on elements.

This was added in [pull request #2339: Add `text-align` override classes](https://github.com/alphagov/govuk-frontend/pull/2339). Thanks to [Ed Horsford](https://github.com/edwardhorsford) for reporting this issue.

#### Define negative spacing using the `govuk-spacing` function

You can now pass the negative equivalent of a point from the spacing scale to the `govuk-spacing` function to get negative spacing.

For example, `govuk-spacing(1)` returns `5px`, and `govuk-spacing(-1)` returns `-5px`.

This was added in [pull request #2348: Allow `govuk-spacing` to output negative spacing](https://github.com/alphagov/govuk-frontend/pull/2348). Thanks to [Chris Hill-Scott](https://github.com/quis) for reporting this issue.

## 3.13.1 (Fix release)

### Fixes

We’ve made fixes to GOV.UK Frontend in the following pull requests:

- [#2264: Improve focus state for radio and checkbox controls in forced colors mode (for example, Windows High Contrast Mode)](https://github.com/alphagov/govuk-frontend/pull/2264) – thanks to [@adamliptrot-oc](https://github.com/adamliptrot-oc) for reporting this issue

- [#2312: Remove `padding-right` from details component](https://github.com/alphagov/govuk-frontend/pull/2312)

## 3.13.0 (Feature release)

### New features

#### Add a 'none' option and 'or' divider to checkboxes

You can now add a 'none' option to checkboxes. For example, 'None of the above' or 'None of these options apply to me'.

Use the 'none' option to [allow users to state that none of the checkboxes apply to them](https://design-system.service.gov.uk/components/checkboxes/#add-an-option-for-none-). Otherwise, users would have to work out that they should leave all the checkboxes unticked.

You can now also add an 'or' divider before the 'none' option. Use the 'or' divider to make the 'none' option more visible to users.

This was added in [pull request #2151: Add 'None of the above' and 'or' divider to checkboxes](https://github.com/alphagov/govuk-frontend/pull/2151). Thanks to [@frankieroberto](https://github.com/frankieroberto) for contributing this improvement.

#### Add a `nonce` attribute to inline scripts

If your service has a Content Security Policy (CSP), you can now add a `nonce` attribute to inline scripts within the Nunjucks page template. To do this, set the `cspNonce` Nunjucks variable. However, you should only add this attribute if you're not able to [include the hash for the inline scripts in your CSP](https://frontend.design-system.service.gov.uk/importing-css-assets-and-javascript/#if-your-javascript-is-not-working-properly).

Make sure you [understand the security implications of using this attribute](https://www.w3.org/TR/CSP/#security-considerations), as wrong implementation could affect your service’s security.

[Read more about how to configure your CSP to work with GOV.UK Frontend](https://frontend.design-system.service.gov.uk/importing-css-assets-and-javascript/#select-and-initialise-part-of-a-page).

This was added in [pull request #2245: Allow the CSP `nonce` attribute to be set on the inline script in the page template](https://github.com/alphagov/govuk-frontend/pull/2245). Thanks to [@natcarey](https://github.com/natcarey) for contributing this issue and its solution.

### Fixes

We've made the following fixes in [pull request #2229: Change approach to fallback PNG in the header to fix blank data URI from triggering Content Security Policy error](https://github.com/alphagov/govuk-frontend/pull/2229):

- fix blank data URI from triggering CSP error
- fix alignment of fallback PNG in the header

We’ve also made fixes in the following pull requests:

- [#2228: Fix display of checkboxes in Internet Explorer 8](https://github.com/alphagov/govuk-frontend/pull/2228)
- [#2237: Fix GOV.UK logo disappearing on light background in Windows High Contrast Mode](https://github.com/alphagov/govuk-frontend/pull/2237)
- [#2251: Disable ink skipping for underlines in hover state](https://github.com/alphagov/govuk-frontend/pull/2251)

## 3.12.0 (Feature release)

### New features

#### Links are easier to read and have a clearer hover state (opt-in)

Links now have underlines that are consistently thinner and a bit further away from the link text.

Links also have a clearer hover state, where the underline gets thicker to make the link stand out to users.

These changes are an opt-in feature because you may:

- need to make changes to your service to introduce these new link styles consistently
- want to avoid opting in if you have links within a [multiple-column layout](https://developer.mozilla.org/en-US/docs/Learn/CSS/CSS_layout/Multiple-column_Layout) in your CSS - there is [a Chromium bug that affects such links](https://github.com/alphagov/govuk-frontend/issues/2204)

To enable this feature, set `$govuk-new-link-styles` to `true` before you import GOV.UK Frontend in your Sass:

```
// application.scss
$govuk-new-link-styles: true;
@import "govuk-frontend/all";
```

If you have created your own link styles, you should review them to ensure their use is consistent across your service.

To make it easier to be consistent in your use of link styles, we’ve also introduced new mixins and modifier classes for:

- removing underlines
- displaying white text on dark backgrounds

These new link styles will be enabled by default in a future major version of GOV.UK Frontend.

This was added in [pull request #2183: Updates to link styles and link hover states](https://github.com/alphagov/govuk-frontend/pull/2183).

#### Style links to remove underlines

You can now remove underlines from links by using either the:

- [`govuk-link-style-no-underline` mixin](http://frontend.design-system.service.gov.uk/sass-api-reference/#govuk-link-style-no-underline) in your Sass, or
- [`govuk-link--no-underline` class](https://design-system.service.gov.uk/styles/typography/#links-without-underlines) in your HTML

An underline still appears when the user hovers their cursor over the link.

This was added in [pull request #2214: Add no-underline mixin and modifier class](https://github.com/alphagov/govuk-frontend/pull/2214).

#### Style links on dark backgrounds

You can now style links on dark backgrounds to use white text colour by using either the:

- [`govuk-link-style-inverse` mixin](http://frontend.design-system.service.gov.uk/sass-api-reference/#govuk-link-style-inverse) in your Sass, or
- [`govuk-link--inverse` class](https://design-system.service.gov.uk/styles/typography/#links-on-dark-backgrounds) in your HTML

This was added in [pull request #2213: Add inverse link mixin and modifier class](https://github.com/alphagov/govuk-frontend/pull/2213).

#### Add links styled as buttons to cookie banners

You can now add links styled as buttons to cookie banners. For example, you can set the **Hide** button to be a link styled as a button that reloads the page. Use this feature if you set non-essential cookies on the server and want to help users keep their place using progressive enhancement.

This feature is enabled by default.

This was added in [pull request #2164: Enable cookie banner to set link styled as a button](https://github.com/alphagov/govuk-frontend/pull/2164).

## 3.11.0 (Feature release)

### New features

#### Allow users to accept or reject cookies with a cookie banner

You can now [use cookie banners](https://design-system.service.gov.uk/components/cookie-banner/) to allow users to accept or reject cookies which are not essential for making your service work.

This was added in [pull request #2131: Add cookie banner component and button groups](https://github.com/alphagov/govuk-frontend/pull/2131).

#### Group buttons and links

You can now use a button group when you place two or more buttons together.

Any links you include within a button group now line up visually with the buttons.

Read more about [button groups on the Design System’s button page](https://design-system.service.gov.uk/components/button/#grouping-buttons).

This was added in [pull request #2114: Add button groups for use in cookie banner](https://github.com/alphagov/govuk-frontend/pull/2114).

#### Change the style of table captions

You can now make table captions larger or smaller by applying the `govuk-table__caption--xl`, `govuk-table__caption--l`, `govuk-table__caption--m` or `govuk-table__caption--s` classes.

This was added in [pull request #2048: Add modifiers for table captions](https://github.com/alphagov/govuk-frontend/pull/2048).

## 3.10.1 (Patch release)

### Fixes

We’ve made fixes to GOV.UK Frontend in the following pull requests:

- [#2035: Fix hairline gap between notification banner header and outer border on high resolution screens in Chrome/Edge (Blink)](https://github.com/alphagov/govuk-frontend/pull/2035)
- [#2036: Explicitly set the text colour for notification banner content, rather than using the user-agent default text colour](https://github.com/alphagov/govuk-frontend/pull/2036)
- [#2042: Wrap notification banner content at 2/3 grid width](https://github.com/alphagov/govuk-frontend/pull/2042)

## 3.10.0 (Feature release)

### New features

#### Update users with notification banners

You can now [use notification banners](https://design-system.service.gov.uk/components/notification-banner/) to tell users about events that occur elsewhere in your service. For example, when they need to complete tasks.

This was added in [pull request #1935: Create notification banner component](https://github.com/alphagov/govuk-frontend/issues/1935).

#### Customise input mode in the date component

You can now change which keyboard type displays for mobile and tablet users. This enables users to enter characters other than numbers when they use the date input. To change the keyboard type, set the `inputmode` when you use the Nunjucks macro options.

This was added in [pull request #1975: Enable custom inputmode for date input component](https://github.com/alphagov/govuk-frontend/pull/1975). Thanks to [@foaly-nr1](https://github.com/foaly-nr1) for contributing this issue.

## 3.9.1 (Fix release)

### Fixes

We’ve made fixes to GOV.UK Frontend in the following pull requests:

- [#1967: Fix navigation links in the header not being announced by screen readers](https://github.com/alphagov/govuk-frontend/pull/1967)

## 3.9.0 (Feature release)

### New features

#### Add a prefix or suffix to a text input component

You can now [use prefixes and suffixes in the text input component](https://design-system.service.gov.uk/components/text-input/#prefixes-and-suffixes) to help users enter things like currencies and measurements.

This was added in [pull request #1816: Add input prefix and suffix](https://github.com/alphagov/govuk-frontend/pull/1816). Thanks to [@simonwhatley](https://github.com/simonwhatley) and the GOV.UK Coronavirus Services Team.

#### Test if your HTML matches GOV.UK Frontend

You can now use our test fixtures to [check you're outputting the same HTML that GOV.UK Frontend uses](http://frontend.design-system.service.gov.uk/testing-your-html/).

This was added in [pull request #1925: Generate fixtures.json files for components on build:package](https://github.com/alphagov/govuk-frontend/pull/1925). Thanks to everyone who fed back on [our test fixtures proposal](https://github.com/alphagov/govuk-frontend/issues/1830#issuecomment-665075842).

#### Customise navigation in the header component

If you use the [header component with navigation](https://design-system.service.gov.uk/components/header/#header-with-service-name-and-navigation), you can now:

- customise the section's `aria-label` text
- add navigation items without links

##### Customise aria-label text

You can use the new:

- `navigationLabel` option to set the `aria-label` text for the navigation section
- `menuButtonLabel` option to set the `aria-label` text for the button that hides or shows the navigation section on mobile

For example:

```javascript
{{ govukHeader({
    navigationLabel: "Custom navigation section aria-label",
    menuButtonLabel: "Custom menu button aria-label"
}) }}
```

The default labels are now:

- **Navigation menu** for `navigationLabel`
- **Show or hide navigation menu** for `menuButtonLabel`

This was added in pull requests:

- [#1905: Set navigation and mobile menu labels of the header component with new options](https://github.com/alphagov/govuk-frontend/pull/1905)
- [#1943: Change header menu button label](https://github.com/alphagov/govuk-frontend/pull/1943) - thanks to [@domoscargin](https://github.com/domoscargin) for raising this issue

##### Add navigation items without links

To add a navigation item without a link, use the `text` or `html` option to add the item but do not use the `href` option.

For example:

```javascript
{{ govukHeader({
    navigation: [
    {
      html: "<form method='post' action='url.com'>
              <input type='submit' class='app-logout-button-style' value='Log out' />
            </form>"
    }
  ]
}) }}
```

## 3.8.1 (Fix release)

### Fixes

We’ve made fixes to GOV.UK Frontend in the following pull requests:

- [#1912: Fix character count shrinking as you go over limit](https://github.com/alphagov/govuk-frontend/pull/1912)

## 3.8.0 (Feature release)

### New features

#### The secondary text colour is now darker

`$govuk-secondary-text-colour` and `govuk-colour("dark-grey")` are now darker so users can more clearly read hint text that uses the colour.

The colour now has a contrast ratio of 7:1 against a white background, and helps hint text meet the WCAG 2.1 (AAA) accessibility standard.

This was added in [pull request #1827: Make dark grey darker](https://github.com/alphagov/govuk-frontend/pull/1827).

#### Error styling for field border thickness is now the same with and without an error

The error styling for the:

- text input, select and textarea components no longer makes the border thicker
- file upload component no longer includes a border around the file upload input

This means it’s easier for users to tell the difference between a field with an error and a field that's focused.

When an error message is about several fields, make sure you're clear which field has the error. You must not rely on users being able to tell which field has the error styling.

This was added in [pull request #1870: Reduce border width of form inputs in the error state](https://github.com/alphagov/govuk-frontend/pull/1870).

#### Set spellcheck with a new option

You can now turn spellcheck on or off in the input, textarea and character count components using the new `spellcheck` option instead of the `attributes` option.

For example:

```javascript
{{ govukInput({
    spellcheck: true
}) }}
```

This was added in pull requests:

- [#1859: Add spellcheck option](https://github.com/alphagov/govuk-frontend/pull/1859)
- [#1869: Add missing spellcheck param to character count](https://github.com/alphagov/govuk-frontend/pull/1869)

### Deprecated features

#### $govuk-border-width-form-element-error

From GOV.UK Frontend v4.0.0, you'll no longer be able to reference the [`$govuk-border-width-form-element-error`](https://frontend.design-system.service.gov.uk/sass-api-reference/#govuk-border-width-form-element-error) Sass setting.

Change any references to `$govuk-border-width-form-element-error` in your Sass code so they reference `$govuk-border-width-form-element` instead.

This was changed in [pull request #1870: Reduce border width of form inputs in the error state](https://github.com/alphagov/govuk-frontend/pull/1870).

### Fixes

We’ve made fixes to GOV.UK Frontend in the following pull requests:

- [#1838: Correctly camel case SVG attributes in the header and footer](https://github.com/alphagov/govuk-frontend/pull/1838)
- [#1842: Preserve the state of conditional reveals when navigating 'back' in the browser](https://github.com/alphagov/govuk-frontend/pull/1842)

- [#1879: Explicitly set outline-offset to remove 1px transparent border in chrome v84](https://github.com/alphagov/govuk-frontend/pull/1879)

## 3.7.0 (Feature release)

### New features

#### Add extra spacing between list items

If a [list](https://design-system.service.gov.uk/styles/typography/#lists) is hard to read because the items run across multiple lines, you can now [add extra spacing between list items](http://design-system.service.gov.uk/styles/typography/#adding-extra-spacing-between-list-items) using the new `govuk-list--spaced` class.

This was added in [pull request #1775: Add list--spaced modifier](https://github.com/alphagov/govuk-frontend/pull/1775). Thanks to [@frankieroberto](https://github.com/frankieroberto) for raising this issue.

#### Use HTML for navigation items in the header

You can now use HTML for a navigation item in the [header](https://design-system.service.gov.uk/components/header/) component, using the new `html` option.

This was added in [pull request #1819: Add the ability to specify HTML for a navigation item](https://github.com/alphagov/govuk-frontend/pull/1819). Thanks to [@adamsilver](https://github.com/adamsilver).

#### Import settings, tools and helpers CSS in one line

You can now import `node_modules/govuk-frontend/govuk/base`, instead of importing `settings`, `helpers` and `tools` separately.

#### Sass now compiles faster

GOV.UK Frontend's Sass files now compile to CSS faster, because we've changed the way dependencies work when you import them.

If you already import `node_modules/govuk-frontend/govuk/all` in your Sass file, you do not need to do anything. Sass will automatically compile faster.

If you import specific parts of GOV.UK Frontend in your Sass file instead, you can now make Sass compile faster by importing `base` then a component's `index` file. This will avoid GOV.UK Frontend importing dependencies multiple times.

For example:

```scss
@import "node_modules/govuk-frontend/govuk/base";

@import "node_modules/govuk-frontend/govuk/core/all";
@import "node_modules/govuk-frontend/govuk/objects/all";

@import "node_modules/govuk-frontend/govuk/components/button/index";
@import "node_modules/govuk-frontend/govuk/components/footer/index";
@import "node_modules/govuk-frontend/govuk/components/header/index";
```

Find out more about [importing CSS](https://frontend.design-system.service.gov.uk/importing-css-assets-and-javascript/#css).

This was added in [pull request #1804: Allow components to be imported without dependencies](https://github.com/alphagov/govuk-frontend/pull/1804). Thanks to [@kevindew](https://github.com/kevindew) for raising this issue.

#### Collapse breadcrumb component on mobile

You can now [collapse the breadcrumb component on mobile](https://design-system.service.gov.uk/components/breadcrumbs/#collapsing-breadcrumbs-on-mobile-devices) using the new `collapseOnMobile` option, so it:

- shows only the first and last items
- does not wrap

This was added in [pull request #1754: Add collapseOnMobile breadcrumbs flag](https://github.com/alphagov/govuk-frontend/pull/1754). Thanks to [@vanitabarrett](https://github.com/vanitabarrett) and [@miaallers](https://github.com/miaallers).

#### Back links are easier to select

The [back link](https://design-system.service.gov.uk/components/back-link/) component is now:

- bigger, so it's easier to select if you're using a touch screen
- more consistent with the design of the breadcrumb component

This was added in [pull request #1753: Make back link arrow consistent with breadcrumb component](https://github.com/alphagov/govuk-frontend/pull/1753). Thanks to [@vanitabarrett](https://github.com/vanitabarrett) and [@miaallers](https://github.com/miaallers).

### Deprecated features

#### Importing from the `core` and `overrides` layers without `base`

If you import specific files from the `core` or `overrides` layers, you’ll now see a deprecation warning when compiling Sass if you do not import `node_modules/govuk-frontend/govuk/base` first.

To fix the warning, import `node_modules/govuk-frontend/govuk/base` first. For example:

```scss
@import "node_modules/govuk-frontend/govuk/base";
@import "node_modules/govuk-frontend/core/typography";
```

If you do not import `node_modules/govuk-frontend/govuk/base` first, your service will no longer work from GOV.UK Frontend v4.0.0.

This was added in [pull request #1807: Warn if importing core, overrides without dependencies](https://github.com/alphagov/govuk-frontend/pull/1807).

### Fixes

We’ve made fixes to GOV.UK Frontend in the following pull requests:

- [#1796: Standardise accordion section headings font size (reduce height of section headings on mobile)](https://github.com/alphagov/govuk-frontend/pull/1796)

## 3.6.0 (Feature release)

### New features

#### Use colours with the tag component

You can now [use colour with tags](https://design-system.service.gov.uk/components/tag/#using-colour-with-tags) to help distinguish between different tags - or to help draw the user’s attention to a tag if it’s especially important.

This also means you should replace the `.govuk-tag--inactive` class with the `.govuk-tag--grey` class. `.govuk-tag--inactive` is now deprecated, and it will be removed in a future release.

[Pull request #1711: Additional Tag modifier classes for different colours](https://github.com/alphagov/govuk-frontend/pull/1711).

#### Hide elements when users print a page

You can now hide elements when users print a page, using the new `govuk-!-display-none-print` class.

[Pull request #1723: Add display override for hiding content when printing](https://github.com/alphagov/govuk-frontend/pull/1723).

#### The `iff` Sass function is now deprecated

You should no longer use the `iff` Sass function. The function is now deprecated, and it will be removed in a future release.

[Pull request #1742: Deprecate iff function](https://github.com/alphagov/govuk-frontend/pull/1742).

## 3.4.0 (Feature release)

### New features

#### Add classes to the page wrapper

If you're using Nunjucks, you can now add classes to the page wrapper using the [`containerClasses` variable](https://design-system.service.gov.uk/styles/page-template/#variables).

[Pull request #1626: Allow creating custom width containers and using them with template](https://github.com/alphagov/govuk-frontend/pull/1626).

#### Set a custom width for wrappers

If you're using Sass, you can now use the `govuk-width-container` mixin to create a custom wrapper class with a specific width. You can then add that class to the following wrappers to override the width of the `govuk-width-container` class:

- [page wrapper](https://design-system.service.gov.uk/styles/layout/#page-wrappers)
- [header container](https://design-system.service.gov.uk/components/header/)
- [footer container](https://design-system.service.gov.uk/components/footer/)

To create your custom wrapper class, include the `govuk-width-container` mixin. Pass in the width in pixels.

For example:

```scss
.app-width-container--wide {
  @include govuk-width-container(1200px);
}
```

If you’re using Nunjucks, you should then add your class using either the:

- `containerClasses` variable in the [page template](https://design-system.service.gov.uk/styles/page-template/#variables)
- `containerClasses` option in the [header](https://design-system.service.gov.uk/components/header/) or [footer](https://design-system.service.gov.uk/components/footer/)

Use the `$govuk-page-width` Sass variable instead if all your pages are the same width.

- [Pull request #1626: Allow creating custom width containers and using them with template](https://github.com/alphagov/govuk-frontend/pull/1626).

#### Add attributes to the `<body>` element of a page

You can now add attributes to the `<body>` element of a page, by using the [`bodyAttributes` variable](https://design-system.service.gov.uk/styles/page-template/#variables) in the page template.

- [Pull request #1623: Allow attributes to be set on template <body>](https://github.com/alphagov/govuk-frontend/pull/1623).

- [Pull request #1631: Fix classes on character count when in error state](https://github.com/alphagov/govuk-frontend/pull/1631).

## 3.3.0 (Feature release)

### New features

#### Allow `lang` to be set on `<title>` and `<main>` of template

You can now set the [lang attribute](https://www.w3.org/International/questions/qa-html-language-declarations) in the title and main of page template.

This will help with scenarios where some of the elements, such as navigation and footer, are in English whereas the title and page content are in a different language.

- [Pull request #1576: Allow `lang` to be set on title and main of template](https://github.com/alphagov/govuk-frontend/pull/1576).

#### Add new override class to hide elements

You can now use the `.govuk-!-display-none` override class to hide elements.

- [Pull request #1586: Add display none override class](https://github.com/alphagov/govuk-frontend/pull/1586).

#### Visual updates to the warning text component

You can now pass attributes to add to the fieldset on the date input component.

[Pull request #1541: Allow date input fieldset attributes to be set](https://github.com/alphagov/govuk-frontend/pull/1541). Thanks to [andrew-mcgregor](https://github.com/andrew-mcgregor) for raising this.

## 3.0.0 (Breaking release)

### Breaking changes

You must make the following changes when you migrate to this release, or your service may break.

#### Update file paths, attributes and class names

To make sure GOV.UK Frontend's files do not conflict with your code, we've moved our package files into a directory called `govuk`.

##### If you’re using Sass

Add `govuk/` after `govuk-frontend/` to `@import` paths in your [Sass](https://sass-lang.com/) file.

For example:

```scss
@import "node_modules/govuk-frontend/govuk/all";
```

If you’ve [added `node_modules/govuk-frontend` as a Sass include path](https://github.com/alphagov/govuk-frontend/blob/master/docs/installation/installing-with-npm.md#optional-resolving-scss-import-paths), add `govuk/` to your `@import` paths:

```scss
@import "govuk/all";
```

##### If you’re using Javascript

You must do the following.

1. Update file paths.
2. Update and add `data-module` attributes.
3. Update CSS class names.

###### Update file paths

You must add `govuk/` to your import paths.

If you're importing `node_modules/govuk-frontend/all.js`, change this import path to `node_modules/govuk-frontend/govuk/all.js`.

If you’re importing a specific path, add `govuk/` after `govuk-frontend/`. For example, if you're importing the button component:

```nunjucks
import Button from 'govuk-frontend/govuk/components/button/button'
```

###### Update and add data-module attributes

You do not need to do anything if you're using Nunjucks macros and the [`initAll`](https://github.com/alphagov/govuk-frontend/blob/master/docs/installation/installing-with-npm.md#option-1-include-javascript) function.

If you are not using Nunjucks macros, add a `govuk-` prefix to `data-module` attribute values. For example:

```html
<div class="govuk-accordion" data-module="govuk-accordion">
...
</div>
```

The [button](https://design-system.service.gov.uk/components/button/) and [details](https://design-system.service.gov.uk/components/details/) components now also use the `data-module` attribute for initialisation. If you are not using Nunjucks macros, add:

- `data-module="govuk-button"` to each `<button>` HTML tag
- `data-module="govuk-details"` to each `<details>` HTML tag

If you're using your own JavaScript code to initialise components, add a `govuk-` prefix to any selectors that find components using the `data-module` attribute.

[Pull request #1443: Ensure GOV.UK Frontend component selectors cannot conflict when initialised](https://github.com/alphagov/govuk-frontend/pull/1443)

###### Update CSS class names

You do not need to do anything if you're using Nunjucks.

If you're using HTML or custom JavaScript, change:

- `js-character-count` to `govuk-js-character-count`
- `js-header-toggle` in the GOV.UK Frontend header component to `govuk-js-header-toggle`

[Pull request #1444: Renames `js-` css prefix to `govuk-js-`](https://github.com/alphagov/govuk-frontend/pull/1444)

##### If you’re using Nunjucks

1. Change the list of paths in `nunjucks.configure` so that the only GOV.UK Frontend path is `node_modules/govuk-frontend/`:

```nunjucks
nunjucks.configure([
  "node_modules/govuk-frontend/"
])
```

2. If you've extended the [page template](https://design-system.service.gov.uk/styles/page-template/), add `govuk/` to the template path:

```nunjucks
{% extends "govuk/template.njk" %}
```

3. Change the import paths in your components so they include `govuk/components/`. For example:

```nunjucks
{% from "govuk/components/breadcrumbs/macro.njk" import govukBreadcrumbs %}
```

##### Update asset paths

In the assets path, add `govuk/` after `govuk-frontend/`:

`/node_modules/govuk-frontend/govuk/assets`

If your code uses Express.js, you must also use the following code in your configuration file:

```javascript
app.use('/assets', express.static(path.join(__dirname, '/node_modules/govuk-frontend/govuk/assets')))
```

Pull requests:

- [#1458: Namespace nunjucks and components](https://github.com/alphagov/govuk-frontend/pull/1458)
- [#1467: Update the main entry point in package.json](https://github.com/alphagov/govuk-frontend/pull/1467)

#### Migrate to the new accessible focus states

The focus state of components now meets the new WCAG 2.1 level AA requirements.

You must [update your component’s focus state](https://design-system.service.gov.uk/get-started/focus-states/) to make your design consistent with our new focus styles.

If you've extended or created components, you can no longer use the `govuk-focusable` or `govuk-focusable-fill` Sass mixins.

If you're using `govuk-focusable`, you must remove it. There’s no direct replacement, so you must [use our Sass variables to make your components consistent](https://design-system.service.gov.uk/get-started/focus-states/#make-other-focusable-elements-accessible) with GOV.UK Frontend.

If you're using `govuk-focusable-fill`, include the `govuk-focused-text` mixin inside your component's `:focus` selector. For example:

```scss
.app-component:focus {
  @include govuk-focused-text;
}
```

Pull requests:

- [#1309: Update links (and things that look like links) to use the new focus style](https://github.com/alphagov/govuk-frontend/pull/1309)
- [#1312: Update form inputs focus to comply with WCAG 2.1](https://github.com/alphagov/govuk-frontend/pull/1312)
- [#1313: Add new focus style to buttons](https://github.com/alphagov/govuk-frontend/pull/1315)
- [#1321: Update footer links to use new focus style](https://github.com/alphagov/govuk-frontend/pull/1321)
- [#1324: Update accordion to use new WCAG 2.1 compliant focus style](https://github.com/alphagov/govuk-frontend/pull/1324)
- [#1326: Update tabs component to WCAG 2.1 compliant focus style](https://github.com/alphagov/govuk-frontend/pull/1326)
- [#1361: Remove `govuk-focusable`, `govuk-focusable-fill` mixins, introduce `govuk-focus-text` mixin](https://github.com/alphagov/govuk-frontend/pull/1361)

#### Update colours

You can now use the following new colour variables that we've added to the [colour palette](https://design-system.service.gov.uk/styles/colour#main-colours):

- dark-blue
- dark-grey
- mid-grey
- light-grey

5 Sass colour variables no longer exist. Replace the following colour variables if you're using Sass:

| Colour variable removed | Suggested replacement |
| ----------------------- | --------------------- |
| bright-red              | red                   |
| grey-1                  | dark-grey             |
| grey-2                  | mid-grey              |
| grey-3                  | light-grey            |
| grey-4                  | light-grey            |

You should check the [contrast ratio of your colours](https://design-system.service.gov.uk/styles/colour#colour-contrast).

If you're not using Sass, change the values of the following colours:

| Colour name | Old value | Replace with |
| ----------- | --------- | ------------ |
| purple      | #2e358b   | #4c2c92      |
| red         | #b10e1e   | #d4351c      |
| yellow      | #ffbf47   | #ffdd00      |
| green       | #006435   | #00703c      |
| grey-2      | #bfc1c3   | #b1b4b6      |
| grey-3      | #dee0e2   | #f3f2f1      |
| grey-4      | #f8f8f8   | #f3f2f1      |
| light-blue  | #2b8cc4   | #5694ca      |
| blue        | #005ea5   | #1d70b8      |
| bright-red  | #df3034   | #d4351c      |

We've also changed the background of the following components:

- buttons - `green` instead of a custom green
- confirmation panels - `green` instead of `turquoise`
- links in their hover state - `dark-blue` instead of `light-blue`

If you're using legacy projects like GOV.UK Elements, you can keep your current colours by [turning on compatibility mode](https://github.com/alphagov/govuk-frontend/blob/master/docs/installation/compatibility.md).

Read our [blog post about why we changed the colour palette](https://designnotes.blog.gov.uk/2019/07/29/weve-updated-the-gov-uk-colours-and-font/)

[Pull request #1288: Update colour palette](https://github.com/alphagov/govuk-frontend/pull/1288).

#### Check the new version of the font

The size and baseline of the Design System's font are now more consistent with other fonts. Text now aligns vertically in text boxes without you needing to adjust it.

If you've extended or created components, you should check that your text is still vertically aligned correctly.

If you're using GOV.UK Frontend and [GOV.UK Template](https://github.com/alphagov/govuk_template), you can [turn on compatibility mode](https://github.com/alphagov/govuk-frontend/blob/master/docs/installation/compatibility.md) to keep using the font from GOV.UK Template.

Pull requests:

- [#1434: Update font to use v2 of GOV.UK Transport font](https://github.com/alphagov/govuk-frontend/pull/1434)
- [#1441: Removing font style adjustments](https://github.com/alphagov/govuk-frontend/pull/1441)

#### Update links from error summary components to radios and checkboxes

If you've linked from an error summary component to the first input in a [radios](https://design-system.service.gov.uk/components/radios/) or [checkboxes](https://design-system.service.gov.uk/components/checkboxes/) component, the link will no longer work.

This is because the `id` of the first input no longer has the suffix `-1`.

If there are links back to radios or checkboxes components in your error summary component, remove `-1` from the end of the `href` attribute.

[Pull request #1426: Make radios and checkboxes components easier to link to from error summary](https://github.com/alphagov/govuk-frontend/pull/1426)

#### Update the markup for tabs

You do not need to do anything if you're using Nunjucks macros.

If you are not using Nunjucks macros, remove the `govuk-tabs__tab--selected` class from the first tab's link, then add the `govuk-tabs__list-item--selected` class to that link's parent list item.

For example:

```html
<li class="govuk-tabs__list-item govuk-tabs__list-item--selected">
  <a class="govuk-tabs__tab" href="#tab1">
    Tab 1
  </a>
</li>
```

[Pull request #1496: Update the focus state for tabs](https://github.com/alphagov/govuk-frontend/pull/1443)

#### Update start button icon

[Start buttons](https://design-system.service.gov.uk/components/button/#start-buttons) have a new icon. Your start buttons will lose their current icons unless you replace the old icon with the new one.

If you're using Nunjucks:

- set the `isStartButton` option to `true`
- remove the `.govuk-button--start` class

For example:

```javascript
govukButton({
  text: "Start now",
  href: "#",
  isStartButton: true
})
```

If you're using HTML, add the SVG code from the [start button example in the Design System](https://design-system.service.gov.uk/components/button/#start-buttons).

[Pull request #1341: Add new start button icon](https://github.com/alphagov/govuk-frontend/pull/1341)

#### Adjust text alignment in tables

Text now aligns to the top of table cells. If you've used a different alignment in a table, you should use your own CSS styles to keep the alignment the same.

For example, to align text in the centre:

```scss
.app-table--vertical-align-middle .govuk-table__header,
.app-table--vertical-align-middle .govuk-table__cell {
  vertical-align: middle;
  ...
}
```

[Pull request #1345: Set 'vertical-align:top' positioning on table headers and cells](https://github.com/alphagov/govuk-frontend/pull/1345)

#### Replace Sass mixins in grids

If you're using the `@govuk-grid-column` Sass mixin to create custom grid classes, you must remove the `$class` parameter.

If you're passing a class name, put the mixin inside your selector. For example:

```scss
.your-class-name {
  @include govuk-grid-column(...)
}
```

You can no longer use the `govuk-grid-row` mixin. You can replace it with the `.govuk-grid-row` class in your HTML.

You must also replace calls to the `grid-width` mixin with calls to the `govuk-grid-width` mixin.

Pull requests:

- [#1376: Remove $class param from @govuk-grid-column mixin](https://github.com/alphagov/govuk-frontend/pull/1376)
- [#1342: Remove grid-width mixin](https://github.com/alphagov/govuk-frontend/pull/1342)
- [#1343: Removes govuk-grid-row mixin](https://github.com/alphagov/govuk-frontend/pull/1343)

#### Rename the border width variable

If you use Sass and you’ve extended or created components that use the border width variable, rename `$govuk-border-width-mobile` to `$govuk-border-width-narrow`.

[Pull request #1287: Rename border-width-mobile to reflect how it's used](https://github.com/alphagov/govuk-frontend/pull/1287)

### New features

#### Add attributes to table headings

You can now add attributes like classes, rowspan and colspan to table row headers.

[Pull request #1367: Allow for classes, rowspan, colspan and attributes on row headers](https://github.com/alphagov/govuk-frontend/pull/1367). Thanks to [edwardhorsford](https://github.com/edwardhorsford).

#### Use page wrapper auto spacing

You can now add the `.govuk-main-wrapper--auto-spacing` modifier class to your `<main>` element to add responsive padding to the top and bottom of the page.

This will add the correct amount of padding depending on if there are elements above the `<main>` element inside the `govuk-width-container` wrapper. Elements above the `<main>` element could include a back link or breadcrumb component.

If you need to control the spacing manually, use the `.govuk-main-wrapper--l` modifier instead.

The `govuk-main-wrapper` and `govuk-main-wrapper--l` Sass mixins are now deprecated. [Contact us](https://design-system.service.gov.uk/get-in-touch/) if you need to continue using these mixins.

[Pull request #1493: Add automatic vertical spacing modifier for main wrapper](https://github.com/alphagov/govuk-frontend/pull/1493)

#### GDS Transport now falls back to Arial in Internet Explorer 8 (IE8)

IE8 will now use Arial instead of GDS Transport.

This is because IE8 requires a very large Embedded Open Type (.eot) font file for external fonts. Arial will take less time to render for IE8 users, who are likely to be on older computers.

[Pull request #1434: Update font to use v2 of GOV.UK Transport font](https://github.com/alphagov/govuk-frontend/pull/1434). Thanks to [@Nooshu](https://github.com/Nooshu).

All form fields now support an initial `aria-describedby` value, populated before the optional hint and error message IDs are appended.

Useful when fields are described by errors or hints on parent fieldsets.

([PR #1347](https://github.com/alphagov/govuk-frontend/pull/1347))

🔧 Fixes:

- Update colour for MHCLG

Fixes the brand colour for MHCLG to their correct corporate "green" brand.

([PR #1259](https://github.com/alphagov/govuk-frontend/pull/1259))

- Ensure fieldset never exceeds max-width

This fix ensures that both WebKit/Blink and Firefox are prevented from expanding their fieldset widths to the content's minimum size.

This was preventing `max-width: 100%` from being applied to select menus inside a fieldset.

See discussion in ["Reset your fieldset"](https://thatemil.com/blog/2015/01/03/reset-your-fieldset/) and raised by [issue #1264](https://github.com/alphagov/govuk-frontend/issues/1264)

([PR #1269](https://github.com/alphagov/govuk-frontend/pull/1269))

🔧 Fixes:

- Add various fixes to the summary list component:

1. Fixes the 1px row height change when borders are removed
     Padding is now adjusted by 1px instead

2. Fixes the text alignment when the actions column isn't added
     So the key column always stays at 30% width

([PR #1259](https://github.com/alphagov/govuk-frontend/pull/1259))

## 2.10.0 (Feature release)

Thanks [Ed Horsford](https://github.com/edwardhorsford) and [Steve Sims](https://github.com/stevesims) for their help on this one.

([PR #1247](https://github.com/alphagov/govuk-frontend/pull/1247))

- Update padding of govuk-main-wrapper

This increases the padding of `govuk-main-wrapper` (on tablet and above) to be more inline with GOV.UK. When updating, your pages will have 10px more white space above and below the 'main' content area.

([PR #1073](https://github.com/alphagov/govuk-frontend/pull/1073))

- Remove error-summary dependence on document.onload

([PR #1215](https://github.com/alphagov/govuk-frontend/pull/1215))

- Ensure font is not loaded twice on slow networks

This is only an issue for users that are using alphagov/govuk_template alongside GOV.UK Frontend.

([PR #1242](https://github.com/alphagov/govuk-frontend/pull/1242))

## 2.8.0 (Feature release)

### Considerations for fixed components such as modals

We have been made aware that the [change to force scroll bars to appear at all times](https://github.com/alphagov/govuk-frontend/pull/1230) can change the behaviour of some components such as modals.

If you're using your own components that rely on the overflow state of the document (such as modals) you should make sure you test those components when updating to this version.

🆕 New features:

- Enable `pattern` attribute for input

You can now set the `pattern` attribute on input fields using the component
  macros:

```js
  {{ govukInput({
    name: "example",
    pattern: "[0-9]*"
  }) }}
  ```

As well as `pattern`, custom attributes can also be added on day/month/year
  inputs (e.g. `data-example`) shown below:

```js
  {{ govukDateInput({
    items: [
      {
        pattern: "[0-9]*",
        attributes: {
          "data-example": "value"
        }
      }
    ]
  }) }}
  ```

([PR #1172](https://github.com/alphagov/govuk-frontend/pull/1172))

- Prevent horizontal jump as scrollbars appear

As content vertical height grows (e.g. autocomplete results appear), browsers
  may add scroll bars causing the page to jump horizontally in position.

To avoid this, re-introduce fix from GOV.UK Template:
  <https://github.com/alphagov/govuk-frontend/issues/1204>

([PR #1230](https://github.com/alphagov/govuk-frontend/pull/1230))

- Accommodate camera notches on new devices (iPhone X, Google Pixel 3 etc)

On newer devices with "camera notches", browsers reserve a safe area in
  landscape orientation (known as pillarboxing) so content isn't obscured.

To avoid this, support has been added for `viewport-fit=cover` as shown here:
  <https://webkit.org/blog/7929/designing-websites-for-iphone-x/>

([PR #1176](https://github.com/alphagov/govuk-frontend/pull/1176))

- Prefix error messages with a visually hidden "Error:", to make it clearer to
  users of assistive technologies

([PR #1221](https://github.com/alphagov/govuk-frontend/pull/1221))

- Prevent accidental multiple submissions of forms

If a user double clicks a submit button in a form, we debounce this event and
  ignore the second click.

HTML data attribute:

```html
  <button class="govuk-button" data-prevent-double-click="true">
    Submit
  </button>
  ```

Nunjucks macro:

```js
  {{ govukButton({
    text: "Submit",
    preventDoubleClick: true
  }) }}
  ```

([PR #1018](https://github.com/alphagov/govuk-frontend/pull/1018))

🔧 Fixes:

- Ensure that files within the core, objects and overrides layers can be
  imported individually

Unlike components, the files within these layers did not previously import
  their dependencies (for example, most of them require the govuk-exports mixin
  but did not import it).

We've also added tests to ensure that files within these layers can be
  imported and rendered to CSS without erroring, which should catch this in the
  future.

Thanks to [Alasdair McLeay](https://github.com/penx) for originally raising a
  PR to fix this.

([PR #1235](https://github.com/alphagov/govuk-frontend/pull/1235))

- Improve word wrapping in summary list component

Thanks to [Edward Horsford](https://github.com/edwardhorsford) and [Lee Kowalkowski](https://github.com/leekowalkowski-hmrc) for their help on this one.

Also thanks to [Malcolm Butler](https://github.com/MoJ-Longbeard) for exploring a [previous version of this fix](https://github.com/alphagov/govuk-frontend/pull/1185).

([PR #1220](https://github.com/alphagov/govuk-frontend/pull/1220))

## 2.7.0 (Feature release)

🆕 New features:

- Added config file for prototype kit.

Added a configuration file for an experimental feature in Prototype kit to allow departments to use their own frontend alongside govuk-frontend

Thanks @matcarey (HMRC) for this contribution

([PR #1102](https://github.com/alphagov/govuk-frontend/pull/1102))

- Disable incorrect iOS/Edge text size adjustments

To cater for non-responsive websites, iOS and Edge automatically increase font sizes (iOS in landscape, Edge in portrait on HiDPI displays).

Since we have already considered typography at these device sizes, this feature is now turned off.

([PR #1178](https://github.com/alphagov/govuk-frontend/pull/1178))

🔧 Fixes:

- Fix wrapping of long lines of text in summary list

Thanks to [@MoJ-Longbeard](https://github.com/MoJ-Longbeard) for raising the issue.

([PR #1169](https://github.com/alphagov/govuk-frontend/pull/1169))

## 2.6.0 (Feature release)

🆕 New features:

- Enable `autocomplete` attributes for input components.

You can now set the `autocomplete` attribute on input, date input and textarea components using the component macros.

This was already possible to do with the `attributes` option but this change highlights the new WCAG 2.1 success criteria [Identify Input Purpose](https://www.w3.org/WAI/WCAG21/Understanding/identify-input-purpose.html) which "is to ensure that the purpose of a form input collecting information about the user can be programmatically determined, so that user agents can extract and present this purpose to users using different modalities".

See [autofill](https://html.spec.whatwg.org/multipage/form-control-infrastructure.html#autofill) for the full list of attributes that can be used.

- On smaller screens it wraps by default
  - It's possible to have multiple actions

([PR #1065](https://github.com/alphagov/govuk-frontend/pull/1065))

🔧 Fixes:

- Update visually hidden class to fix ordering issue in VoiceOver OSX

We have fixed an issue in VoiceOver OSX where using the `govuk-visually-hidden` class in links would result in the text being announced out of order.

We also now recommend to use aria-label or aria-labelledby where appropriate.

Thanks to @stevenaproctor and the accessibility team at HMRC for letting us know about this issue.

🆕 New features:

- Scroll to label or legend when linked from error summary

When users click links in the error summary, the corresponding label or legend
  will now be moved to the top of the viewport, rather than the input. This
  means that the context for the input remains on-screen.

([PR #1056](https://github.com/alphagov/govuk-frontend/pull/1056))

- Label or legend are announced for NVDA users when navigating to an input from
  the error summary

([PR #1056](https://github.com/alphagov/govuk-frontend/pull/1056))

- Allow form group classes on date, file upload, input, select and textarea

All remaining form groups should allow additional classes, like with radios and checkboxes

([PR #1059](https://github.com/alphagov/govuk-frontend/pull/1059))

🔧 Fixes:

- Remove implicit dependency on Element for classList

([PR #1063](https://github.com/alphagov/govuk-frontend/pull/1063))

- Single field with error should have 'aria-describeby' attribute

Although we discourage using checkboxes without fieldsets, this fix
  ensures that if there are no fieldset then the aria-describeby will
  still be usable by screenreaders by adding the element ids to the checkbox
  input elements 'aria-describeby' attribute.

([PR #1054](https://github.com/alphagov/govuk-frontend/pull/1054))

## 2.3.0 (Feature release)

🆕 New features:

- Add important parameter to visually hidden sass mixins

Optional parameter added to `govuk-visually-hidden` and `govuk-visually-hidden-focusable` mixins (defaults to true)

([PR #1037](https://github.com/alphagov/govuk-frontend/pull/1037))

- Add support for attributes on table cells

Can now use the familiar `attrubutes: {}` pattern to add various
  attributes such as `id` or `data-attr` to cells within tables

([PR #1045](https://github.com/alphagov/govuk-frontend/pull/1045))

- Allow form group classes on radios and checkboxes

We now provide a way to add classes to the radio and checkbox form-group wrapper

([PR #1043](https://github.com/alphagov/govuk-frontend/pull/1043))

🔧 Fixes:

- Fix anchor links in tabs component panels

([PR #1031](https://github.com/alphagov/govuk-frontend/pull/1031))

- Fix IE8 support in builds in the `dist/` folder

([PR #1035](https://github.com/alphagov/govuk-frontend/pull/1035))

## 2.2.0 (Feature release)

🆕 New features:

- Allow classes on table header and row cells

Optional classes attribute can now be used on table header and row cell item
  in the Nunjucks macro

([PR #1015](https://github.com/alphagov/govuk-frontend/pull/1015))

- Add character count component

([PR #959](https://github.com/alphagov/govuk-frontend/pull/959))

🔧 Fixes:

- Apply max-width to the `<select>` element

The `<select>` element's width is governed by the widths of its `<option>`'s.

When the text in the options grows large, the element can grow to > 100% of the width of its container and break the layout.

([PR #1013](https://github.com/alphagov/govuk-frontend/pull/1013))

- Prevent product name in header from wrapping

Currently the product name in the header wraps when the space shrinks which doesn't look great.

Adding `display: inline-table` prevents that so that the product name as a whole drops to a new line when space is shrunk.

([PR #1007](https://github.com/alphagov/govuk-frontend/pull/1007))

- Set text colour for radios divider

([PR 1023](https://github.com/alphagov/govuk-frontend/pull/1023))

- Stop links styled as button from being dragged

Moving the mouse over a link while its button is depressed causes the
  browser’s dragging behaviour to trigger (and prevents the `click`
  event from firing). This is contrary to how actual `<button>` elements
  work. This pull request makes the behaviour of links styled as buttons
  consistent with that of buttons.

([PR #1020](https://github.com/alphagov/govuk-frontend/pull/1020))

## 2.1.0 (Feature release)

🆕 New features:

- Allow additional 'meta' content in the footer

You can now pass additional 'meta' content (as `meta.html` or `meta.text`)
  which will appear below any meta links, above the OGL license. This is ideal
  for, for example, the 'Built by Department Name' colophon.

([PR #990](https://github.com/alphagov/govuk-frontend/pull/990))

- Allow attributes to be added to some child items in header, footer, breadcrumbs, tabs and error-summary components

You can now pass additional attributes to links in header, footer, breadcrumbs, tabs and error-summary components

([PR #993](https://github.com/alphagov/govuk-frontend/pull/993))

- Fix issue with conditional form content and inline form controls

When inline variant of form controls is used with conditional content, we force
  it to display block. This is to avoid breaking and confusing styling as it is
  a combination we don't recommend.

([PR #970](https://github.com/alphagov/govuk-frontend/pull/970))

- Add component options (arguments) as `macro-options.json` to `package`

We want to be able to expose these options to GOV.UK Design System. This change includes them as `yaml` in `src/components` and adds a build step to transform them to `JSON` and copy them to `package/components`. It also adds a test to check if the copied files are valid JSON and contain expected attributes.

([PR #998](https://github.com/alphagov/govuk-frontend/pull/998))

🔧 Fixes:

- Fix mobile menu button submitting parent forms

The menu `<button>` didn’t have an explicit `type` set, which meant that it
  defaulted to `type=“submit”`.

This meant that if the header was inside a form (as it is in the Design System
  examples, but we can imagine other scenarios where this would be the case)
  clicking the menu button would submit the form.

In most cases this would also cause the page to reload, which closes the menu.

([PR #994](https://github.com/alphagov/govuk-frontend/pull/994))

- Fix flash of unstyled content in tabs component

([PR #1000](https://github.com/alphagov/govuk-frontend/pull/1000))

- Add 48px favicon

Microsoft recommends including at least a 48x48px favicon.

([PR #986](https://github.com/alphagov/govuk-frontend/pull/986))

- Update `browsersList` in `package.json` to reflect our supported browsers

`browsersList` is used by PostCSS in our current build to determine which browser prefixes or rules to generate for the built CSS files. This PR adds rules to specify that the browsers in our [browser matrix](https://github.com/alphagov/govuk-frontend#browser-support) should always be prefixed for. Additionally, any browser with more than 0.1% of the global market share is prefixed for.

In terms of changes to our built CSS, this means that `-webkit-box-sizing` and `-webkit-box-shadow` prefixes will be removed - neither of these prefixes are required by desktop Safari 5.1 or later so this seems a fairly safe change to make.

([PR #1002](https://github.com/alphagov/govuk-frontend/pull/1002))

## 2.0.0 (Breaking change)

💥 Breaking changes:

- Set panel component's title heading level to 1 as default

We think the panel title should be the h1 in the majority of cases, so we made
  it the default.

If you have need to change the Panel component heading to something other than
  h1, you can do so by specifying `headingLevel: <number>` in the Nunjucks
  macro.

([PR #967](https://github.com/alphagov/govuk-frontend/pull/967))

- Remove deprecated `govuk-visually-hidden-focussable` class name

In 1.1 release we added a new, correctly spelt
  `govuk-visually-hidden-focusable` CSS class and marked the old one as
  deprecated.

To migrate you need to change `govuk-visually-hidden-focussable` to
  `govuk-visually-hidden-focusable` in your codebase.

([PR #968](https://github.com/alphagov/govuk-frontend/pull/968))

- Remove name-based width logic from date-input component

In [1.1 release](https://github.com/alphagov/govuk-frontend/pull/857/files#diff-e94394b2ac1d4f73991af98e4fa34fa3L32)
  we removed styling which made the year field 4 characters wide, but was
  coupled to the field's name.

However, to avoid making this a breaking release, we added logic to
  automatically add the width classes based on the name.

We are now removing this behaviour. Instead, users need pass explicit classes
  for each field in the `items` object for the desired width of the input field.

If you are not passing items at all, you will get the default items which include these classes.

If you are using the Nunjucks macro, you need to provide a width class for
  each item, for example:

```
  {{ govukDateInput({
    "id": "dob",
    "name": "dob",
    "fieldset": {
      "legend": {
        "text": "What is your date of birth?"
      }
    },
    "items": [
      {
        "name": "day",
        "classes": "govuk-input--width-2"
      },
      {
        "name": "month",
        "classes": "govuk-input--width-2"
      },
      {
        "name": "year",
        "classes": "govuk-input--width-4"
      }
    ]
  }) }}
  ```

If you are using plain HTML, you need to manually add a width-based class, such
  as `govuk-input--width-2` or `govuk-input--width-4` to the input fields.

([PR #969](https://github.com/alphagov/govuk-frontend/pull/969))

- Rename `name` argument of date-input component to `namePrefix`.

This is better reflective of the purpose of the argument, which is to prefix the `name` attribute of `items`. This is consistent with other components which use the name `idPrefix` to explain similar functionality.

If your project currently uses this optional argument with the date-input macro, you need to rename all instances of it to `namePrefix` (NB: this argument shouldn't be confused with the `items.{}.name` attribute which hasn't changed.)

([PR #984](https://github.com/alphagov/govuk-frontend/pull/984))

- Turn off [compatibility mode](./docs/installation/installing-with-npm.md#compatibility-mode) by default for [GOV.UK Elements](https://github.com/alphagov/govuk_elements), [GOV.UK Template](https://github.com/alphagov/govuk_template), [GOV.UK Frontend Toolkit](https://github.com/alphagov/govuk_frontend_toolkit)

You do not need to make any changes if you do not use these projects alongside GOV.UK Frontend.

To migrate include the SCSS variables that correspond with the projects you depend on before importing GOV.UK Frontend styles into your app:

```SCSS
  // application.scss
  $govuk-compatibility-govukfrontendtoolkit: true;
  $govuk-compatibility-govuktemplate: true;
  $govuk-compatibility-govukelements: true;
  @import "govuk-frontend/all";
  ```

([PR #981](https://github.com/alphagov/govuk-frontend/pull/981))

- Turn on relative typography (rem) by default

This allows for end-users to adjust GOV.UK Frontend components by setting their font size in their browser.

If you are using GOV.UK Frontend on with no other frameworks this should not break your project.

If you need to change this setting for compatibility with [GOV.UK Elements](https://github.com/alphagov/govuk_elements), [GOV.UK Template](https://github.com/alphagov/govuk_template), [GOV.UK Frontend Toolkit](https://github.com/alphagov/govuk_frontend_toolkit) consider enabling [compatibility mode](./docs/installation/installing-with-npm.md#compatibility-mode).

Otherwise, set `$govuk-typography-use-rem` to `false` before importing GOV.UK Frontend styles into your app:

```SCSS
  // application.scss
  $govuk-typography-use-rem: false;
  @import "govuk-frontend/all";
  ```

([PR #981](https://github.com/alphagov/govuk-frontend/pull/981))

- Remove anchor styling in govuk-lists

This was an undocumented feature of lists.

To migrate we recommend using adding `.govuk-link` class to any anchors within a govuk-list.

If you would like to replicate this functionality without adding a class you can also enable [global styles](https://github.com/alphagov/govuk-frontend/blob/master/docs/installation/installing-with-npm.md#global-styles) (Note: global styles are enabled by default in the GOV.UK Prototype Kit)

([PR #985](https://github.com/alphagov/govuk-frontend/pull/985))

- Remove the width declaration from the `<select>` component

The `<select>` component’s width will now be defined by it’s content. This addresses some accessibility issues with the select being 100% wide by default. If you want to style your select to be 100% wide we have added a new override class `.govuk-!-width-full` to allow this.

([PR #960](https://github.com/alphagov/govuk-frontend/pull/960))

- Use text colour on focus for better contrast

Updates the focus styles of links in GOV.UK Frontend so they pass WCAG contrast requirements.

([PR #982](https://github.com/alphagov/govuk-frontend/pull/982))

🆕 New features:

- Add a new width override class `.govuk-!-width-full`

You can now override elements that have an undefined or smaller percentage width to be 100% width of their container.

([PR #960](https://github.com/alphagov/govuk-frontend/pull/960))

- Allow attributes on select items

You can now provide attributes on select items
  `attributes: { 'data-attribute': 'value' }`

([PR #977](https://github.com/alphagov/govuk-frontend/pull/977))

🔧 Fixes:

- Textareas can now only be resized vertically, to prevent them being resized
  outside of their container bounds. Additionally, they now have a minimum
  height to prevent them being resized smaller than a text input.

([PR #976](https://github.com/alphagov/govuk-frontend/pull/976))

- Defend tables against GOV.UK Elements code
  ([PR #983](https://github.com/alphagov/govuk-frontend/pull/983))

## 1.3.0 (Feature release)

🆕 New features:

- Allow attributes on checkboxes/radios

You can now provide attributes on checkbox and radio items
  `attributes: { 'data-attribute': 'value' }`

([PR #942](https://github.com/alphagov/govuk-frontend/pull/942))

🔧 Fixes:

- Fix incorrect panel title bottom margin with optional text

Margin is only added when panel text is provided

([PR #936](https://github.com/alphagov/govuk-frontend/pull/936))

- Remove template whitespace

Remove leading whitespace before the doctype in the page template.
  Some older browser will be forced into 'quirks mode' if there is whitespace before the doctype.

([PR #949](https://github.com/alphagov/govuk-frontend/pull/949))

- Remove additional dotted outline from focussed buttons in Firefox

This was already the intended behaviour, but a minor typo (: rather than ::)
  meant that it wasn't being applied.

([PR #951](https://github.com/alphagov/govuk-frontend/pull/951))

- Update date input component to use `display: inline-block`
  ([PR #938](https://github.com/alphagov/govuk-frontend/pull/938))

- Change spacing relationship on default and small legends and hints
  ([PR #940](https://github.com/alphagov/govuk-frontend/pull/940))

- Adjust tag component padding to compensate for font spacing
  ([PR #955](https://github.com/alphagov/govuk-frontend/pull/955))

## 1.2.0 (Feature release)

🆕 New features:

- Allow for optional divider between radio items

You can now provide a divider item (e.g "or") to separate items
  ([PR #849](https://github.com/alphagov/govuk-frontend/pull/849))

- Allow og:image meta tag url to be set independantly
  Image url for the opengraph image needs to be absolute and
  can now be overwritten by setting the `assetUrl` variable.
  ([PR #847](https://github.com/alphagov/govuk-frontend/pull/847))

- Only underline the logo in the header on underline when users have overridden
  colours in their browser, rather than it appearing underlined all the time
  ([PR #926](https://github.com/alphagov/govuk-frontend/pull/926))

- Allow for optional hint for each radio and checkbox item

You can now pass a hint object (or add in html) to each radio
  and checkbox item to display the hint
  ([PR #846](https://github.com/alphagov/govuk-frontend/pull/846))

- Allow additional classes to be added to the radio and checkbox items

You can now provide `label: { classes: 'extra-class' }` to each item.

([PR #880](https://github.com/alphagov/govuk-frontend/pull/880))

🔧 Fixes:

- Replace conflicting `js-hidden` class used within the tabs component with a new modifier class.
  Because this class is defined and used within the JavaScript, no markup changes are required.
  ([PR #916](https://github.com/alphagov/govuk-frontend/pull/916))
- Use `get-function` when calling a Sass function as passing a string to `call()``
  is deprecated and will be illegal in Sass 4.0
  ([PR #919](https://github.com/alphagov/govuk-frontend/pull/919))

- Fix flash of unstyled content with conditional reveals (Radios and Checkboxes)

If the conditional reveal JavaScript is slow to execute it can result in showing the user their contents briefly which can be jarring.

([PR #885](https://github.com/alphagov/govuk-frontend/pull/885))

## 1.1.1 (Fix release)

🔧 Fixes:

- Update details behaviour to remove margin-bottom for all elements
  ([PR #900](https://github.com/alphagov/govuk-frontend/pull/900))

- Update internal padding of tab content in the tabs component
  ([PR #886](https://github.com/alphagov/govuk-frontend/pull/886))

- Fixes an issue where clicking the revealed content in browsers that do not
  support the native details element causes the details element to collapse.
  ([PR #912](https://github.com/alphagov/govuk-frontend/pull/912))

- Fixes an issue where clicking the revealed content within a details element
  toggles the aria-expanded attribute on the summary element and the aria-hidden
  attribute on the content element, causing them to get out of sync with the
  visible state of the component.
  ([PR #912](https://github.com/alphagov/govuk-frontend/pull/912))

- Fixes an issue where it's not possible to make any field that does not have
  the name ‘year’ use any other width than 2 characters
  ([PR #908](https://github.com/alphagov/govuk-frontend/pull/908))

- Fix undefined class displaying in date input
  ([PR #913](https://github.com/alphagov/govuk-frontend/pull/913))

## 1.1.0 (Feature release)

🆕 New features:

- Add `govuk-visually-hidden-focusable` class

Adds `.govuk-visually-hidden-focusable` and deprecates `.govuk-visually-hidden-focussable` in order to fix the typo in the class name. Please consider updating your code as the next major release will remove the deprecated class.

([PR #859](https://github.com/alphagov/govuk-frontend/pull/859))

- Allow panel component title heading to be customisable.

You can now specify a heading level by providing
  `headingLevel: <number>` parameter. Default is `2`.
  ([PR #853](https://github.com/alphagov/govuk-frontend/pull/853))

- Update date input component

Allow the `name` and `id` attributes to be passed individually for each input item.

Rely on `classes` instead of item names to set the width of input items.

Add default (day, month, year) date input items if no items are being specified

([PR #857](https://github.com/alphagov/govuk-frontend/pull/857))

- The typography scale can now be converted from pixels to rem automatically,
  with pixels also being provided as a fallback for older browsers.

This feature is disabled by default - in order to use it you will need to set
  `$govuk-typography-use-rem: true` and ensure that `$govuk-root-font-size` is
  set to the effective size of your root (html) element. For new projects, this
  should be the default of 16px so you don't have to do anything. For projects
  that use alphagov/govuk_template this should be 10px.

The intention is to enable this by default in the next major version:
  <https://github.com/alphagov/govuk-frontend/issues/868>

([PR #858](https://github.com/alphagov/govuk-frontend/pull/858))

🔧 Fixes:

- Remove mistakenly applied 5px bottom margin from radio and checkbox
  labels.
  ([PR #883](https://github.com/alphagov/govuk-frontend/pull/883))

- Apply `display:block` to `.govuk-main-wrapper`

In IE11 `main` element is set to `display:inline` so padding
  and margins aren't applied.
  ([PR #863](https://github.com/alphagov/govuk-frontend/pull/863)))

- Line-heights are now converted from pixels to relative 'unit-less' values
  in order to prevent issues when resizing text in the browser.
  ([PR #837](https://github.com/alphagov/govuk-frontend/pull/837) and
  [PR #848](https://github.com/alphagov/govuk-frontend/pull/848))

- Add bottom margin to Tabs component
  All components (or outer layer components) have a bottom margin
  applied to them so spacing feels automatic.
  ([PR #841](https://github.com/alphagov/govuk-frontend/pull/841))

- Update Crown copyright link
  Update the Crown copyright link on the National Archives so
  we don't send users on an unnecessary redirect.
  ([PR #824](https://github.com/alphagov/govuk-frontend/pull/824))

- Fixes radio and checkbox labels extending full width of page
  ([PR #821](https://github.com/alphagov/govuk-frontend/pull/821))

- Prevent the exclamation mark in the warning text component from being
  selectable, which also excludes it when it is copied as part of a wider body
  of text
  ([PR #856](https://github.com/alphagov/govuk-frontend/pull/856))

- Add customised colours handling for warning text

By adding a border to this component, when a user customises their colour settings
  they will still see a circle even if the background is removed.
  ([PR #852](https://github.com/alphagov/govuk-frontend/pull/852))

- Fixes a bug where the phase banner incorrectly uses a font-size of 19px when
  global styles are enabled
  ([PR #877](https://github.com/alphagov/govuk-frontend/pull/877))

- Add outlines to Radios and Checkboxes for customised colour users

Now when a [user customises their colours](https://accessibility.blog.gov.uk/2017/03/27/how-users-change-colours-on-websites/),
  they should see a focus state on both Radios and Checkboxes.
  ([PR #854](https://github.com/alphagov/govuk-frontend/pull/854))

- Add outline to tag for customised colour users

Now when a [user customises their colours](https://accessibility.blog.gov.uk/2017/03/27/how-users-change-colours-on-websites/),
  the tag component still keeps it's meaning.
  ([PR #855](https://github.com/alphagov/govuk-frontend/pull/855))

- Define size of table in `px` rather than `em`

This brings the styling of tables inline with rest of GOV.UK Frontend which no longer uses `em` for measurements.

This change very slightly increases the padding of table cells on mobile viewport as the use of `em` meant the font size set in the table was used to calculate padding. `padding-top` and `padding-bottom` of cells increase by 1.5px respectively which very slightly increases the height of the table on mobile.

In the unlikely case that your UI has a dependency on tables being a certain fixed height of mobile viewport, this change might affect you.

([PR #845](https://github.com/alphagov/govuk-frontend/pull/845))

- Fix header component's reliance on markup whitespace

We have had issues where the header component can render incorrectly if the markup contains whitespace,
  for example if it has been pretty printed.

This changes the header component to use float based columns similar to how the grid system works.

## 0.0.32 (Breaking release)

**This release changes the name of package.** It's now published as `govuk-frontend` on `npm`.

💥 Breaking changes:

- The default build of the GOV.UK Frontend JavaScript now does not initialize all components automatically.

This allows you to initialize only the components you need, and gives you finer control over when the JavaScript for GOV.UK Frontend runs.

To migrate your project you need to change

```html
    <script src="{path-to-govuk-frontend}/all.js"></script>
  ```

```html
    <script src="{path-to-govuk-frontend}/all.js"></script>
    <script>window.GOVUKFrontend.initAll()</script>
  ```

Now, if you only want to initialize a specific component you can now do so by:

```html
    <script src="{path-to-govuk-frontend}/all.js"></script>
    <script>
      var Button = window.GOVUKFrontend.Button
      new Button(document).init()
    </script>
  ```

Note: If you are importing JavaScript with a bundler, this is not likely to change anything for you.
  ([PR #759](https://github.com/alphagov/govuk-frontend/pull/759))

- Consistently structure the Details and Button component, so that they can be instantiated the same as the other components.

If you're using `GOVUKFrontend.initAll()` you do not need to make any changes, otherwise you need to change

```html
    <script>
      new Button().init()
      new Details().init()
    </script>
  ```

```html
    <script>
      new Button(document).init()

var $details = document.querySelectorAll('details')
      nodeListForEach($details, function ($detail) {
        new Details($detail).init()
      })
    </script>
  ```

([PR #761](https://github.com/alphagov/govuk-frontend/pull/761))

- All sass-mq settings have now been made private. We are now exposing new
  settings to allow you to customise breakpoints and responsive behaviour:

- `$govuk-breakpoints` - Map of breakpoint definitions
  - `$govuk-show-breakpoints` - Whether to show the current breakpoint in the
    top right corner
  - `$govuk-ie8-breakpoint` - Breakpoint to rasterize to for IE8

If you are overriding any settings prefixed with `$mq-` in your application
  you will need to update to the use the new `$govuk-` prefixed settings.

([PR #748](https://github.com/alphagov/govuk-frontend/pull/748))

- Font settings have been renamed:

- `$govuk-font-stack` has been renamed to `$govuk-font-family`
  - `$govuk-font-stack-tabular` has been renamed to `$govuk-font-family-tabular`
  - `$govuk-font-stack-print` has been renamed to `$govuk-font-family-print`

([PR #748](https://github.com/alphagov/govuk-frontend/pull/748))

- Spacing has been refactored. You will need to update Sass that currently uses GOV.UK Frontend spacing:

- Instead of

```css
  $govuk-spacing-scale-*
  ```

use

```css
  govuk-spacing(*)
  ```

where `*` is the number on the spacing scale. The scale itself has remained the same so that `$govuk-spacing-scale-3` corresponds to `govuk-spacing(3)`. This change allows us to control the error messaging when incorrect values are used and to deprecate variables. The values of spacing variables can also be overridden by consumers.

- Instead of:

```css
  @include govuk-responsive-margin($govuk-spacing-responsive-2, "bottom");
  @include govuk-responsive-padding($govuk-spacing-responsive-2, "bottom");
  ```

use

```css
  @include govuk-responsive-margin(2, "bottom");
  @include govuk-responsive-padding(2, "bottom");
  ```

This change, again, allows us to control the error messaging since spacing variables are not exposed directly. Also, the spacing scale itself has not changed so that `$govuk-spacing-responsive-2` corresponds to `2` when passed to the padding and margin mixins.

This PR also updates tests and sass-docs of spacing variables and helpers.

Additionally, this PR hardcodes the value of `$govuk-gutter`, see PR for more details.

([PR #779](https://github.com/alphagov/govuk-frontend/pull/779))

- Remove `pageStart` block from template, as could result in rendering issues in older IE.
  ([PR #765](https://github.com/alphagov/govuk-frontend/pull/765))

- You should no longer call the `mq` mixin directly - you should replace any
  calls to it from your own code with `govuk-media-query` which accepts the same
  arguments. All mixins and settings that start with `mq-` should be considered
  private – they could be removed in the future without notice.
  ([PR #763](https://github.com/alphagov/govuk-frontend/pull/763))

- All of the shorthand 'font' mixins (e.g. `govuk-font-bold-80`,
  `govuk-font-regular-tabular-19`), have been removed and replaced with calls to
  a new mixin `govuk-font`. If you are using these mixins in your application
  you will need to update your code to call `govuk-font` instead.

([PR #772](https://github.com/alphagov/govuk-frontend/pull/772))

- The font maps are no longer as individual variables (e.g. `$govuk-font-80`) -
  they are all now part of one single `$govuk-typography-scale` map. Instead of
  passing font maps to `govuk-typography-responsive` you should now pass the
  desktop font size (e.g. `govuk-typography-responsive(80)` or
  `govuk-typography-responsive($size: 80)`.

([PR #772](https://github.com/alphagov/govuk-frontend/pull/772))

- All organisation variables (e.g. `$govuk-cabinet-office`) have been moved into
  a single `$govuk-colours-organisations` map. If you need to use an
  organisation colour in your own code, you should use the new
  `govuk-organisation-colour` function:

```scss
  .element {
    color: govuk-organisation-colour(cabinet-office);
  }
  ```

Note that this function will return 'web-safe' colours by default. You can
  pass $websafe: false to get the non-websafe colour.

- The colour palette variables (e.g. `$govuk-green`) have been moved into a
  new single `$govuk-colours` map. If you need to reference a colour within your
  application you should use the new `govuk-colour` function:

```scss
  .element {
    color: govuk-colour("green");
  }
  ```

Tints (`$govuk-green-50`, `$govuk-green-25`) have been removed from the colour
  palette.

- A number of the colours have been renamed to use more neutral names:

- `mauve` → `light-purple`
  - `fuchsia` → `bright-purple`
  - `baby-pink` → `light-pink`
  - `mellow-red` → `bright-red`
  - `grass-green` → `light-green`

- The 'circle shape' object (`.govuk-circle`) which was used by the warning text
  component's '!' icon has been removed and the `govuk-warning-text__icon` class
  has been updated to make it circular without the need for another class.

([PR #782](https://github.com/alphagov/govuk-frontend/pull/782))

- Removal of `govuk-prose-scope`
  We don't have confidence that the prose scope is well understood –
  without further research / better documentation it's safer to remove it for now.

If you are currently using prose-scope, you should revert to applying classes to
  individual headings, lists and hr elements.
  In version [0.0.29-alpha](https://github.com/alphagov/govuk-frontend/releases/tag/v0.0.29-alpha)
  release we have added the option to enable global link and paragraph styles.

If you're using a recent version of the Private Beta Prototype kit,
  this is enabled by default.

([PR #778](https://github.com/alphagov/govuk-frontend/pull/778))

- Make override classes consistently verbose
  Based on [feedback from the community](https://gist.github.com/nickcolley/f135e89ed4b679355b0ab47135b38ee8)
  we have made the override classes consistent where previously some where verbose and some where shorthand.

We've made the decision to remove the 'r' for responsive, this was hard to remember and users found this confusing.

To migrate you will need to replace any instances of:

- `.govuk-!-f-{size}` with `.govuk-!-font-size-{size}`
  - `.govuk-!-w-{weight}` with `.govuk-!-font-weight-{weight}`
  - `.govuk-!-m{direction}-r{scale}` with `.govuk-!-margin-{direction}-{scale}`
  - `.govuk-!-p{direction}-r{scale}` with `.govuk-!-padding-{direction}-{scale}`

For example if you were using:

- `.govuk-!-mb-r5` you would need to change this to `.govuk-!-margin-bottom-5`
  - `.govuk-!-f-24` you would need to change this to `.govuk-!-font-size-24`

## 0.0.29-alpha (Breaking release)

💥 Breaking changes:

- Restructure project to enable it to be published as a single package

The [new project structure](<(./src/README.md)>) matches our ITCSS inspired layers and is published as a single package as `@govuk-frontend/frontend`.

You will need to:

- Update your npm dependencies to use `@govuk-frontend/frontend`
  - Update your SCSS import paths to match the new package name and folder structure.

If you're importing everything at once:

```CSS
  @import "node_modules/@govuk-frontend/frontend/all";
  ```

If you're importing individual components:

```CSS
  @import "node_modules/@govuk-frontend/frontend/components/button/button";
  ```

See the [main README](./README.md) for up-to-date installation instructions.

([PR #680](https://github.com/alphagov/govuk-frontend/pull/680))

- Error Messages and Hints have been moved out Label and Fieldset components.

They are no longer nested within the label or legend.
  They are associated with the input or with the fieldset using aria-describedby.

Hint has been made into a new component similar to Error Message.

If you're using markup, you will need to update the old markup:

```HTML
  <label class="govuk-c-label" for="national-insurance-number">
    National Insurance number
    <span class="govuk-c-label__hint">
      It’s on your National Insurance card, benefit letter, payslip or P60. For example, ‘QQ 12 34 56 C’.
    </span>
    <span class="govuk-c-error-message">
      Error message goes here
    </span>
  </label>
  <input class="govuk-c-input govuk-c-input--error" id="national-insurance-number" name="national-insurance-number" type="text">
  ```

With the new markup:

```HTML
  <label class="govuk-label" for="national-insurance-number">
    National Insurance number
  </label>
  <span id="national-insurance-number-hint" class="govuk-hint">
    It’s on your <i>National Insurance card</i>, benefit letter, payslip or P60. For example, ‘QQ 12 34 56 C’.
  </span>
  <span id="national-insurance-number-error" class="govuk-error-message">
    Error message goes here
  </span>
  <input class="govuk-input govuk-input--error" id="national-insurance-number" name="test-name-3" type="text" aria-describedby="national-insurance-number-hint national-insurance-number-error">
  ```

If you're using macros:

The fieldset macro no longer accepts `legendHintText` or `legendHintHtml` -
  these parameters are now passed to the hint component which accepts `text` or
  `html`. The date-input, checkboxes and radios components have been updated to
  use the new Hint component.

The label macro no longer accepts `hintText` or `hintHtml` - these parameters
  are now passed to the hint component which accepts `text` or `html`. The
  file-upload, input, select and textarea components have been updated to use the
  new Hint component.

For example, this example macro call for a File Upload component:

```njk
  {{ govukFileUpload({
    "id": "file-upload",
    "name": "photo",
    "label": {
      "text": "Upload your photo",
      "hintText": "Your photo may be in your Pictures, Photos, Downloads or Desktop folder."
    }
  }) }}
  ```

would now be:

```njk
  {{ govukFileUpload({
    "id": "file-upload",
    "name": "photo",
    "label": {
      "text": "Upload your photo"
    },
    "hint": {
      "text": "Your photo may be in your Pictures, Photos, Downloads or Desktop folder."
    }
  }) }}
  ```

For more examples of the new markup and Nunjucks macros see the GOV.UK Design System [Question Pages pattern](https://govuk-design-system-production.cloudapps.digital/patterns/question-pages/)

([PR #681](https://github.com/alphagov/govuk-frontend/pull/681))

- The date-input component now sets an explicit `group` role on the fieldset
  to force JAWS 18 to announce the error message and hint.
  ([PR #681](https://github.com/alphagov/govuk-frontend/pull/681))

- The label component macro now accepts an `isPageHeading` argument which determines
  whether the label itself should be wrapped in an h1:

```html
  <h1 class="govuk-label-wrapper">
    <label class="govuk-label">What is your National Insurance number?</label>
  </h1>
  ```

The `.govuk-label-wrapper` removes the margins from the heading so that the
  presence of the `h1` has no effect on the styling of the label.

([PR #684](https://github.com/alphagov/govuk-frontend/pull/684))

- Added new modifier classes for labels to allow you to create a label that
  visually corresponds to the equivalent heading class (for example, a
  `.govuk-label--xl` will have the same font size and weight as a
  `.govuk-heading-xl`)

([PR #684](https://github.com/alphagov/govuk-frontend/pull/684))

- The arguments for a fieldset's legend have been rolled up into an object. For
  example, the following macro call:

```
  {{ govukFieldset({
    legendText: "What is your date of birth?"
  }) }}
  ```

would now be:

```
  {{ govukFieldset({
    legend: {
      text: "What is your date of birth?"
    }
  }) }}
  ```

The `legend` object can also accept new `classes` and `arguments`

Components that use the fieldset component have been updated to reflect these
  changes.

([PR #684](https://github.com/alphagov/govuk-frontend/pull/684))

- The fieldset component has a new parameter legend.isPageHeading, which defines
  whether the legend text should be wrapped in an h1:

```html
  <legend class="govuk-fieldset__legend">
    <h1 class="govuk-fieldset__heading">Have you changed your name?</h1>
  </legend>
  ```

The `.govuk-fieldset__heading` class ensures that the `<h1>` inherits its
  properties from the legend, so that the presence of the `h1` has no effect on
  its styling.

([PR #684](https://github.com/alphagov/govuk-frontend/pull/684))

- Added new modifier classes for legends to allow you to create a legend that
  visually corresponds to the equivalent heading class (for example, a
  `.govuk-fieldset__legend--xl` will have the same font size and weight as a
  `.govuk-heading-xl`)

([PR #684](https://github.com/alphagov/govuk-frontend/pull/684))

- Remove -c -o -h layer prefixes
  ([PR #644](https://github.com/alphagov/govuk-frontend/pull/644))
  In user research and in feedback from Private Beta partners we
  learned that users didn't really understand what -o, -c and -h prefixes
  stand for or why they're useful.

They also introduced additional cognitive load when composing classes,
  having to remember which suffix the classname contains.

If you're using markup, you will need to:

- Remove -o, -c and -h prefixes from class names in your markup

For example, change:

```HTML
  <button class="govuk-c-button">Save and continue</button>
  ```

Into:

```HTML
  <button class="govuk-button">Save and continue</button>
  ```

- Simplify grid syntax and introduce grid-row and column mixins.

Based on user research feedback we have simplified the grid classes
  to a more concise naming structure.

You will need to:

- Change grid class names in your markup

For example, change:

```HTML
  <div class="govuk-o-grid">
    <div class="govuk-o-grid__item govuk-o-grid__item--two-thirds">
      
    </div>
    <div class="govuk-o-grid__item govuk-o-grid__item--one-third">
      
    </div>
  </div>
  ```

Into:

```HTML
  <div class="govuk-grid-row">
    <div class="govuk-grid-column-two-thirds">
      
    </div>
    <div class="govuk-grid-column-one-third">
      
    </div>
  </div>
  ```

We have also introduced two mixins
  to help generate additional or custom grid styles and widths,
  see original pull request for usage.

Hovever, we do include them in the [GOV.UK Prototype Kit](https://github.com/alphagov/govuk-prototype-kit-private-beta) to speed up prototyping.

To include global styles, you can set `$govuk-global-styles` variable to `true`.

## 0.0.28-alpha (Breaking release)

Fixes incomplete release from `packages/` and `dist/` in 0.0.27-alpha release.
Missing files were:

- `globals/tools/_compatibility.scss`
- `globals/tools/_ie8.scss`
- `globals/settings/_compatibility.scss`
- `globals/settings/_ie8.scss`

## 0.0.27-alpha (Breaking release)

💥 Breaking changes:

- Removed an (undocumented) modifier `govuk-c-radio__item--inline` which made
  radio buttons inline, in favour of a new block-level modifier
  `govuk-c-radios--inline` which will automatically make all the radio buttons
  within that block inline.
  (PR [#607](https://github.com/alphagov/govuk-frontend/pull/607))
- Prefix `$global-images` variable
  (PR [#615](https://github.com/alphagov/govuk-frontend/pull/615))
- Simplified how we build stylesheets that target old versions of IE:

- Removed styles that target IE6 and IE7
  - Replaced IE mixins with a simpler version for targeting IE8 specifically
    without having to specify versions
  - Add a new tool mixin to easily exclude styles when targeting IE8
  - Automatically set $mq-responsive based on the value of the $govuk-is-ie8
    variable.

If you are building an IE8 stylesheet for your application you'll need to
  update it to reference the new variable $govuk-is-ie8 – see the README for
  details.
  (PR [#631](https://github.com/alphagov/govuk-frontend/pull/631))

- Rename captionSize table argument to captionClasses ([PR #643](https://github.com/alphagov/govuk-frontend/pull/643))

🔧 Fixes:

- Link styles, as well as links within the back-link, breadcrumbs, button,
  error summary, footer and skip link components defend against the
  `a:link:focus` selector in GOV.UK Template, which was overriding focussed
  links to always use the dark blue link colour for text.
  (PR [#609](https://github.com/alphagov/govuk-frontend/pull/609))
- Fix table captions to allow heading classes
  (PR [#633](https://github.com/alphagov/govuk-frontend/pull/633))

  design does not include back links, breadcrumbs or phase banners
  (PR [#602](https://github.com/alphagov/govuk-frontend/pull/602))
- Added a new `.govuk-link--text-colour` modifier to make links use the same
  colour as the text.
  (PR [#609](https://github.com/alphagov/govuk-frontend/pull/609))
- Introduce new mixins for link styles (muted links, text links) and update
  the existing link classes to use them
  (PR [#609](https://github.com/alphagov/govuk-frontend/pull/609))

  include styles that 'counter' styles from the existing products
  (e.g. GOV.UK Template)
  (PR [#609](https://github.com/alphagov/govuk-frontend/pull/609))
- The back link, breadcrumbs and skip link have been updated to use the
  text style link mixin
  (PR [#609](https://github.com/alphagov/govuk-frontend/pull/609))
- Add limited width inputs
  (PR [#626](https://github.com/alphagov/govuk-frontend/pull/626))
- Add details polyfill. This is automatically initialised in the main JS. (PR [#610](https://github.com/alphagov/govuk-frontend/pull/610))
- Add button polyfill. This is automatically initialised in the main JS. [#572](https://github.com/alphagov/govuk-frontend/pull/572))

Note: Our JavaScript work is ongoing. In the next release of GOV.UK Frontend both of our script will be modularised and split into common functions. This will allow you to use the polyfills in your bundler/build pipeline. For this reason, you might want to wait until the next release before adding these polyfill scripts into your project.

  type="text" (PR [#568](https://github.com/alphagov/govuk-frontend/pull/568))

  a transparent border which is visible when overriding colours in the browser
  (PR [#552](https://github.com/alphagov/govuk-frontend/pull/552))

  (PR [#551](https://github.com/alphagov/govuk-frontend/pull/551))

🏠 Internal:

  corresponding classes the prose scope extends have been updated to provide a

  to be specific about which occurrences of the class are meant to be extended.
  (PR [#550](https://github.com/alphagov/govuk-frontend/pull/550))
