# Change Log

## [1.10.15] - 2026-10-29

### Changed

- Upgraded Python dependencies other than `nltk`. Note that if you are
  using third-party Python packages, you may encounter dependency
  conflicts. It is possible that your interviews will need to be
  updated.
- Upgraded CodeMirror.

## [1.10.14] - 2026-10-22

### Changed

- Upgraded `CairoSVG`, `certifi`, `Mako`, `multidict`, `PyJWT`,
  `urllib3`, and `Werkzeug`.

### Fixed

- Avoid red shadow on signature images added to PDF files.

## [1.10.13] - 2026-10-01

### Fixed

- Issue with converting question to data when the `code` variant of
  `show if` caused a multiple choice question not to appear on the
  screen.
- The "Are you sure?" message was appearing when a new Playground
  interview was saved.

## [1.10.12] - 2026-09-27

### Added

- Configuration directive for setting a default value for the `send
  question data` feature.

### Fixed

- Adjusted the code that calls S3 so that it is compatible with
  servers that do not return `Content-Type`.
- Added `DBPORT` to `Docker/env.list`.

## [1.10.11] - 2026-09-20

### Fixed

- The address autocomplete feature was not actually as configurable as
  the documentation suggested.
- The `css class` of a radio or checkbox item was attached to the
  `<input>` but not to the `<label>`. It is now attached to both.

## [1.10.10] - 2026-09-12

### Fixed

- Input sanitization for LDAP login method.

## [1.10.9] - 2026-09-12

### Changed

- The `editable: False` option for `pdf template file` is implemented
  a different way, which should provide improved accessibility.
- For purposes of salutations and pronouns, gender is
  case-insensitive.

## [1.10.8] - 2026-09-07

### Changed

- The `_edit_button()` and `_delete_button()` methods now have a third
  positional argument, `item`. *Note that this is a breaking change*
  if you use `_edit_button()` or `_delete_button()`, so you will need
  to update your methods.
- Checkboxes and radio buttons no longer use JavaScript.
- Users of screen readers will hear "Deleted" after pressing a
  "Delete" button on a `table`.
- Changed aria settings of the elements containing flash messages, so
  that messages are announced to screen readers. If you have modified
  `alert container html` and/or `alert html`, you may want to make
  note of these changes.
- Users of screen readers now see a "Skip to main content" link that
  focuses the question, bypassing navigation.
- When the spinner appears, users of screen readers will hear
  "Please wait."
- When fields appear due to a `show if` being triggered, users of
  screen readers will hear "Additional fields have appeared."
- Users of screen readers will hear the list of sections in the
  navigation bar as separate items.
- The progress bar's `aria-valuenow` is now always an integer.
- Updated the progressive disclosure recipe to use
  `<details>`/`<summary>`.
- Changed the HTML of "terms" to add `role="button"` and to use a
  trigger based on focus.
- Removed `bootstrap-fileinput` plugin for styling file input
  elements.
- After a new screen is loaded, the focus will switch either to a form
  field or to the text of the `question`.
- Removed the unnecessary `visually-hidden` `<legend>` messages that
  provided context (e.g. "press one of the following buttons");
  replaced `<fieldset>` with `<div>`.
- The `log()` function now accepts a `priority` of `aria`, which shows
  a message in a `visually-hidden` `<div>` inside of `#daflash`.

### Fixed

- Fixed issue with the session id not being set in the global
  variables immediately after a `new_session` is created.
- Prevented error message appearing under some circumstances when a
  package is deleted.

## [1.10.7] - 2026-08-01

### Fixed

- Downgraded `nltk` in order to avoid requiring a system upgrade.

## [1.10.6] - 2026-08-01

### Added

- New permission `read_packages` so that users without
  `admin` or `developer` privileges can use the API to obtain a list
  of packages.

### Changed

- Upgraded Python dependencies. Note that if you are using third-party
  Python packages, you may encounter dependency conflicts. It is
  possible that your interviews will need to be updated.
- Python 3.12 or later is now required, so if you are running an old
  Docker container with Python 3.10 or earlier, you cannot upgrade
  beyond version 1.10.5.
- Upgraded Font Awesome and CodeMirror.
- `hide continue button` and `disable continue button` now accept a
  YAML boolean rather than only a Python expression.
- The `submit` screen part can be specified on a `question`.
- `DAOAuth` can be configured with `extra_auth_args` and
  `url_style_short`.
- The Package Management page shows the same report as the
  Configuration page.

### Fixed

- Action buttons were not listed in data version of a question.
- Bug where the use of `value()` could raise an exception.

## [1.10.5] - 2026-07-13

### Fixed

- Issue with `_reorder_buttons()`.
- `role="alert"` not added to flash messages that are part of the
  HTML.

## [1.10.4] - 2026-07-06

### Fixed

- Issue with the Playground variables list not being able to be
  generated.

## [1.10.3] - 2026-07-04

### Fixed

- Issue with `table css class`.
- Issue with Google Drive and OneDrive sync.

## [1.10.2] - 2026-07-01

### Added

- The `enable translation` Configuration directive.

### Changed

- If `enable playground` is false, the Playground page, the Utilities
  page, and other code associated with interview development will not
  be loaded.

### Fixed

- Problem with Celery not being fully configured.
- Bug in fax configuration.
- Added input santiation on admin-only endpoint /logfile.
- Added Twilio verification to /sms endpoint.

## [1.10.1] - 2026-06-29

### Fixed

- Errors related to add-on package installation.

## [1.10.0] - 2026-06-28

### Added

- The `enable api`, `enable email server`, `enable object storage`,
  `enable daglobal`, `enable json storage`, `enable sms interface`,
  `enable faxing`, and `enable tts` Configuration directives.
- The `pip trusted host` Configuration directive.

### Changed

- The internal organization of the source code has changed
  significantly. Documented functionality has not changed, but if your
  code imports undocumented names, you may find that the name has
  moved to another module. Testing your interviews on a development
  server is recommended before upgrading a production server.
- `pluggy` is now used to give `docassemble.base` access to
  functionality in `docassemble.webapp`.
- Flask blueprints are now used for features of
  `docassemble.webapp`. Configuration directives like `enable
  training` and `allow log viewing` will now prevent the importing of
  the code underlying the disabled features. Turning off these
  features can decrease uWSGI memory usage by 29%.
- SQLAlchemy models now inherit from `sqlalchemy.org.DeclarativeBase`
  rather than `db.model`.
- Celery tasks are now invoked using signatures.
- Added a dependency on `pyopenssl` not because it is needed, but
  because a version conflict with `cryptography` will prevent the
  web application from starting.

### Fixed

- Issue with `list collect` and `input type: hidden`.

## [1.9.13] - 2026-06-03

### Fixed

- Issue with converting fillable PDFs to PDF/A.

## [1.9.12] - 2026-05-11

  or above.

## [1.9.10] - 2026-05-03

### Fixed

- Pickle error introduced in 1.9.9.

## [1.9.9] - 2026-05-03

### Changed

- In the Docker image, the underlying operating system is upgraded
  from 24.04 to 26.04, the version of PostgreSQL in the image is
  upgraded from 16 to 18, and the version of Python in the image is
  upgraded from 3.12 to 3.14. Note that Python 3.14 may raise errors
  that Python 3.12 did not, or it may change which versions of
  third-party Python packages are available to be installed. (System
  upgrade required.)
- `unoconv` has been replaced with `unoserver`. The `enable unoconv`
  and `ENABLEUNOCONV` settings have not changed names. (System upgrade
  required.)
- When images are included in documents assembled using Pandoc or
  `docx template file`, alt text is included.
- The `prevent going back` modifier can now refer to a Python
  expression.

### Fixed

- The use of keymaps with CodeMirror was only functional for emacs; it
  is now functional for `emacs`, `vscode`, or `vim`.
- Raw attachments are now included when attachments are downloaded as
  a ZIP file.

## [1.9.8] - 2026-04-12

### Changed

- The instructions for writing Python modules that define `SQLObject`
  have changed.
- If you include a `variables snapshot db` item in your configuration,
  and there is any problem connecting to the database, the web
  application will not start, and you will need to fix the problem
  using command line tools, just as if you made a mistake in the `db`
  configuration.

### Fixed

- Typo in `setuptools` specification of packages generated by the
  Playground.
- Non-thread-safe methods of loading external databases in the
  `SQLObject` and `variables snapshot db` features.
- Issue with converting Markdown to PDF when the Markdown includes
  tables, with the latest version of Pandoc.
- Issue with `alembic` disabling `logging`.
- The `numpy` and `scipy` packages were inadvertently upgraded,
  preventing Python 3.10 users from upgrading.
- The `include_docx_template()` function did not handle non-string
  keyword arguments.

## [1.9.7] - 2026-04-05

### Changed

- Removed unnecessary Python dependencies from `docassemble.webapp`
  and `docassemble.base`.
- Removed all dependencies from `docassemble.demo`. If you want to be
  able to run all of the demo interviews, you will need to install
  `ics`, `openai`, `anthropic`, `gspread`, and `matplotlib` manually.
- Upgraded `setuptools`.
- Improved debugging of `CustomDataType` JavaScript.
- Made changes to the code for compatibility with Python 3.13.
- Changed the default value of `user can request developer account` to
  `False`.
- Allowed `auth0` configuration to set an `audience domain` different
  from the `domain`.

### Fixed

- Problem with NGINX log rotation.

## [1.9.6] - 2026-03-27

### Fixed

- Removed dependency on `telnyx`.

## [1.9.5] - 2026-03-24

### Fixed

- Issue with upgrade of `werkzeug` and `flask`.

## [1.9.4] - 2026-03-24

### Changed

- Upgraded `werkzeug` and `flask`.

### Fixed

- Issue introduced in 1.9.3 that prevented the `nltk` daemon from
  starting.

## [1.9.3] - 2026-03-23

### Added

- Files in `docassemble.demo` for the recipe in the documentation
  that demonstrates the `AIHelper` class.

### Changed

- The `objects from file` block and the `objects_from_file()` function
  now return a `DAList` instead of a `list` when `use_objects` is
  true and a list of items is encountered in the data structure.
- Downgraded `numpy`, `scipy`, and `scikit-learn` to allow Python 3.10
  to continue to be used.
- Upgraded `bootstrap-fileinput`.
- Migrated the websockets interface from `eventlet` to `gevent`.
- Moved code that depends on `nltk` into a daemon in order to optimize
  restart speed (system upgrade required).
- Moved some package loads from server start time to runtime in order
  to optimize restart speed.
- Updated restart process so that code runs in parallel.
- A restart after a Configuration change no longer runs
  `create_tables`.
- Applied security updates recommended by `dependabot`.
- Upgraded `docxcompose`.
- Updated documentation links and test scripts.
- Changed names of buttons in the Profile settings.

### Fixed

- Truncated `pip` logs to avoid errors during upgrade process.
- Issue with default values of custom data types after a `validation
  code` validation error.

## [1.9.2] - 2026-01-27

### Added

- The `allow external auth to bypass local auth` Configuration
  directive.

### Changed

- The `.bates_number()` method of `DAFile` now accepts parameters
  `offset_horizontal`, `offset_vertical`, and `font_size`.
- Upgraded `azure-core`, `wheel`, `numpy`, and `pyasn1`.
- Downgraded `contourpy` to avoid requiring Python 3.11.

## [1.9.1] - 2026-01-11

### Fixed

- Applied security-related patch upgrades.
- Issue with `include_docx_template()` used in a Celery process.

## [1.9.0] - 2025-12-31

### Added

- The `.cancel_add_or_edit()` method of `DADict`.
- The methods `_edit_button()`, `_delete_button()`, and
  `_add_action_button()` of the `DADict` class, so that `DADict` can
  be subclassed for customizing the appearance of these buttons.
- The `remove()` class method of `DAGlobal` that can be used to delete
  any key from the data store, for any given base.

### Changed

- Upgraded Python dependencies. Note that if you are using third-party
  Python packages, you may encounter dependency conflicts. It is
  possible that your interviews will need to be updated.
- Upgraded Font Awesome, Bootstrap, and CodeMirror.
- Use process-local rather than thread-local variables to store global
  information in the context of the Celery background task system.
- The `plain()`, `bold()`, and `italic()` functions will return the
  empty string if given blank space.
- Added additional information to Mako error messages.
- The `.complete_elements()` method of `DAList` and `DADict` now
  returns an object of the same class, rather than a pure Python data
  structure.
- The Google Drive sync and OneDrive sync result page now wait for
  the server to finish restarting.

### Fixed

- Avoided `KeyError` error messages related to `gathering_mode` and
  `save_status`.
- Avoided translation of non-user-facing Mako template text in field
  modifiers.
- Fix to dictionary gathering.
- The restart process from the Configuration page could show a 502
  error to the user when the Python app is behind a reverse proxy.
- The Microsoft Azure mail sending feature did not support sending to
  bcc recipients.

## [1.8.18] - 2025-11-01

### Fixed

- Bugs with the Monitor system introduced in 1.8.0.
- Bug where generated `pyproject.toml` files contained the license in
  the wrong place.

## [1.8.17] - 2025-10-05

### Added

- Support for using Basic Auth when using Gotenberg.

### Fixed

- Make symbolic links in `files` relative instead of absolute.
- Prevent the `temporary` and `once_temporary` parameters to
  `interview_url()` and `interview_url_action()` from passing through
  to the URL.
- When single-server mode is in use and the `db` database is remote,
  avoid creating or restoring the `db` database locally.
- The daily cron job should backup the local PostgreSQL database even
  if there is a non-PostgreSQL database as the main database.
- Only call `supervisorctl` if `supervisord` is in use.
- Incorrect output filename when using CloudConvert.

## [1.8.16] - 2025-09-27

### Fixed

- Issue introduced in 1.8.15 related to unpickling Celery return
  values.

## [1.8.15] - 2025-09-27

### Added

- The `celery task routes` Configuration directive.

### Changed

- The `mmdc()` function in `docassemble.base.mermaid` is
  deprecated. The module will be removed in a future version.

### Fixed

- The `continue button field` information was not submitted when
  `maximum image size` feature was used.
- If a signature image after trimming is very small, the trimmed
  version is not used.

## [1.8.14] - 2025-09-15

### Added

- The `login_method` and `phone_number` attributes of `user_info()`.
- The `log to std` Configuration directive to log all output to
  STDERR.
- The `enable training` Configuration directive for disabling the
  Train page.
- The `enable monitor` Configuration directive for disabling the
  Monitor page.

## [1.8.13] - 2025-09-07

### Added

- On the Playground Packages page, if the GitHub button is clicked,
  developers can deselect particular files from the commit.

### Changed

- The number of fonts installed in the underlying Ubuntu operating is
  reduced to the minimum fonts required by `libreoffice`, `texlive`,
  `ttf-mscorefonts-installer`, `fonts-liberation`, and
  `fonts-dejavu-core`. The removal of these fonts may affect DOCX to
  PDF conversion, especially if you are using languages other than
  English. If the environment variable `DAEXTRAFONTS` is `true`, then
  these additional fonts will be installed during container
  startup. You can also install particular fonts using the `PACKAGES`
  environment variable. This change only takes effect on new
  installations or system upgrades.
- Likewise, the Google Fonts will now be installed when the container
  starts, and only if the environment variable `DAGOOGLEFONTS` is
  `true`. This change only takes effect on new installations or system
  upgrades.

### Fixed

- Made `ruamel.yaml` objects thread-local due to issues on `arm64`
  architectures.

## [1.8.12] - 2025-09-01

### Added
- The `'wait'` option for the `command()` function, which causes the
  user's web browser to wait a number of seconds and then query the
  interview logic again.
- The `BackgroundAction` object for calling `background_action()` and
  retrieving the result transparently.
- The `[NO_EMOJIS]` command to turn off interpretation of inline icons
  (e.g. `:face-smile:`).

### Fixed
- Bug with `interview delete days by filename` when days are `0`.
- Service account authentication with `DAGoogleAPI` is now using a
  different method that does not cause `google-api-python-client` to
  trigger an exception.

## [1.8.11] - 2025-08-21

### Changed
- The `action_call` JavaScript function takes a fifth parameter
  (`readOnly`). If set to a true value, the server processes the
  action without saving any changes to the interview answers, and
  without preventing other concurrent processes from accessing the
  interview answers.
- The `/api/session/action` takes an optional data value `read_only`,
  which behaves similarly.
- The `run_action_in_session()` function takes an optional keyword
  parameter `read_only`, which behaves similarly.

### Fixed
- Issue with `use nginx to serve files` on the Logs page.
- Issue with input validation on the License field of the Playground
  Packages page.

## [1.8.10] - 2025-08-18

### Changed
- When `set_save_status('ignore')` is called, the lock on the
  interview answers will be released. After
  `set_save_status('ignore')` is called, the save status cannot be
  changed to something else.

### Fixed
- Issues with compatibility with Python 3.10.

## [1.8.9] - 2025-08-17

### Changed
- Incorporated `szimek/signature_pad` JavaScript into the operation of
  `datatype: signature`.

### Fixed
- Updated advanced usage of `address autocomplete` in light of the
  switch to the "Places API (New)" API.

## [1.8.8] - 2025-08-15

### Fixed
- Error when installing add-on packages created by earlier versions.

## [1.8.7] - 2025-08-14

### Added
- Support for single-sign-on with Authentik.
- Support for sending email with Microsoft Azure using the Graph API.

### Fixed
- On the Playground Packages page, adapted the input validation on the
  License field to better align with PEP 621 and PEP 639.

## [1.8.6] - 2025-08-12

### Fixed
- Issues with comboboxes.

## [1.8.5] - 2025-08-11

### Fixed
- Issue with pyproject.toml files.
- Issue with comboboxes.

## [1.8.4] - 2025-08-10

- Revised Redis code for compatibility with Redis servers.
- Revised datetime code for compatibility with Python 3.10.

## [1.8.3] - 2025-08-10

### Fixed
- Downgraded `scipy` and `contourpy` for compatibility with Python 3.10.

## [1.8.2] - 2025-08-10

### Fixed
- Downgraded `numpy` for compatibility with Python 3.10.

## [1.8.1] - 2025-08-10

### Fixed
- Dependency problem with 1.8.0.

## [1.8.0] - 2025-08-10

### Added
- The `javascript defer` Configuration directive. If set to `True`,
  then the `<script>` tags that load JavaScript files will have the
  `defer` tag set. This is recommended for speeding up the loading of
  the page.
- The `use nginx to serve files` Configuration directive. If set to
  `True`, then file downloads will be served in a more efficient
  manner, transferring the load from Python to NGINX to process the
  contents of the file. Since this feature requires a change to the
  NGINX configuration file template, a system upgrade is required if
  you want to enable this feature. Alternatively, you can manually
  edit the NGINX configuration file template.
- Methods `_reorder_buttons()`, `_edit_button()`, `_delete_button()`,
  and `_add_action_button()` of the `DAList` class, so that `DAList`
  can be subclassed for customizing the appearance of these buttons.
- The Configuration directive `use places api new` under `google` for
  enabling use of the Google "Places API (New)."

### Changed
- Upgraded Python dependencies. Note that if you are using third-party
  Python packages, you may encounter dependency conflicts. It is
  possible that your interviews will need to be updated.
- Upgraded Font Awesome, Bootstrap, and CodeMirror.
- The default action for the menu/navigation bar `exit link` is now
  `leave` (which leaves interview answers intact) instead of `exit`
  (which deletes interview answers).
- On the Playground Packages page, the License must now contain a
  valid SPDX identifier for a license, like `MIT` or `GPL-3.0`.
- Changed the behavior of the `.get()` method of `DADict` so that its
  behavior does not differ from the `.get()` method of `dict`.
- Packages created from the Playground will now have a
  `pyproject.toml` file as well as a `setup.py` file.
- When packages are imported, the `pyproject.toml` file will be
  parsed, if it is present.
- The Google "Places API (New)" is now supported for the `address
  autocomplete` feature. For backwards compatibility, this is not
  enabled by default. Set `use places api new: True` under the
  `google` directive in the Configuration to enable use of the new
  API. You will need to enable the API in your Google Cloud
  Console first.
- When `use places api new` is `True`, then when `address
  autocomplete` is used and there is a field for the `zip` attribute
  of the `Address`, it will be populated with the ZIP+4, if available.
- When `datatype: ajax` is used, the button on the input element is
  non-functional.
- When the `script` modifier on a `question` is used, the contents
  should no longer contain `<script>` and `</script>` tags; if present
  they will be stripped out. Using `script` modifiers is discouraged;
  it is better to use a JavaScript file and listen for the
  `daPageLoad` event.
- Replaced `variables_snapshot_connection()` with
  `variables_snapshot_connect()`. For backwards compatibility,
  `variables_snapshot_connection()` still works the same way.

### Fixed
- Adjusted for Sendgrid reversing order of attachments.

## [1.7.7] - 2025-06-10

### Added
- The `describe file types` attachment modifier.

### Fixed
- Issue with retrieving the JSON representation of `question` that
  uses `list collect` and `uncheck others`.

## [1.7.6] - 2025-05-23

### Added
- The `datalist` input type.

### Fixed
- Issue with `error page javascript` not running under some
  circumstances.
- Issue where `depends on` would not be triggered by changes to
  variables on a `list collect` screen unless the variable was the
  variable being sought.
- Using `.add_action()` on a `DADict` no longer requires that the
  interview logic runs `.gather()` on the `DADict`.

## [1.7.5] - 2025-05-11

### Added
- `error page` as a page type customizable in the Configuration.

### Fixed
- `rtf to docx` format did not work with standalone `attachment`
  blocks.
- Issue with popovers triggered by `focus` events.
- Issue with `list collect` and `show if`.

## [1.7.4] - 2025-04-30

### Fixed
- Issue with Convert API.
- Stack trace shown when not expected.

## [1.7.1] - 2025-04-13

### Added
- The `DASSLCIPHERS` environment variable and `nginx ssl ciphers`
  Configuration directive for controlling the `ssl_ciphers` NGINX
  configuration option.
### Fixed
- Problem when `valid formats` with `code` was used with `docx
  template file`.

## [1.7.0] - 2025-04-09

### Added
- Under `attachment`, `valid formats` can now contain `code`.

### Changed
- Upgraded Python dependencies. Note that if you are using third-party
  Python packages, you may encounter dependency conflicts. It is
  possible that your interviews will need to be updated.
- Upgraded Font Awesome, Bootstrap, and CodeMirror.
- In the container, upgraded Python version from 3.10 to 3.12.
- Dropped Twitter sign-on support.
- The Playground Packages page, when generating a package, will
  specify a dependency using a GitHub URL if the package was loaded on
  the server from a GitHub URL.

## [1.6.5] - 2025-03-04

### Fixed
- Bug introduced in 1.6.4, affecting miniOrange users only.

## [1.6.4] - 2025-03-01

### Added
- The `allow external auth with multiple methods` Configuration
  directive.
- The miniOrange WordPress plugin external authentication method.

### Changed
- Users who registered with one external authentication method cannot
  log in using a different authentication method connected to the same
  email address unless the `allow external auth with multiple methods`
  Configuration directive is set to `True`.

### Fixed
- Trapped exception where service account credentials contain invalid
  JSON.

## [1.6.3] - 2025-02-16

### Fixed
- Setting `label above field: False` did not work as intended.
- Running `.geocode()` will now set the `zip` attribute.

## [1.6.2] - 2024-12-24

  allow the presented table to be filtered and sorted.

### Changed
- Upgraded Python dependencies. Note that if you are using third-party
  Python packages, you may encounter dependency conflicts. It is
  possible that your interviews will need to be updated.
- Upgraded Font Awesome, CodeMirror, and Socket.IO.

### Fixed
- The Share button in the Playground provided a relative URL instead
  of an absolute URL.

## [1.5.16] - 2024-10-16

### Changed
- The `address autocomplete` will now populate the `.sublocality`
  field with `sublocality`, `sublocality_level_1`,
  `sublocality_level_2`, whichever is first available.
- URL parameters `utm_source`, `utm_medium`, `utm_campaign`,
  `utm_term`, and `utm_content` will be preserved when analytics is
  configured and the `/run` endpoint is used.
- Upgraded Pandoc to version 3.5.11 (system upgrade required).

## [1.5.15] - 2024-10-13

### Fixed
- Problem with the `wrap lines in playground` feature.

## [1.5.14] - 2024-10-03

### Fixed
- Issue with `objects` block when a variable name is index of an
  attribute.

## [1.5.13] - 2024-10-01

### Fixed
- Issue with `object_checkboxes` and `object_multiselect` when used as
  elements in a `DAList`.

## [1.5.12] - 2024-09-30

### Changed
- Upgraded pikepdf.

### Fixed
- Issue with `object_checkboxes` and `object_multiselect` when used as
  elements in a `DAList` or `DADict`.

## [1.5.11] - 2024-09-26

### Changed
- Different appearance when a document is reduced to a thumbnail
  image.

### Fixed
- When a new Playground is initialized, the name of the YAML file was
  missing in the sidebar dropdown and the share link.
- When a "flash" message with the Bootstap color "success" was shown
  at the top of the screen, the timeout for removing the message
  could remove messages that the user had not yet had the opportunity
  to read.
- In a `review` screen, error messages about invalid variable names
  were not shown in all cases where the variable name was invalid.

## [1.5.10] - 2024-09-19

### Added
- Option in the `/api/playground` GET endpoint for downloading the ZIP
  file of a Playground package.

## [1.5.9] - 2024-09-18

### Fixed
- Downgraded `pikepdf` to fix problem with populating PDF fields.

## [1.5.8] - 2024-09-16

### Added
- The `.cancel_add_or_edit()` method of `DAList`.

### Changed
- The browser's use of dark mode is now remembered as part of the
  session data, and screenshots in the Playground match the mode.
- Upgraded `cryptography` and `flask-cors`.
- When `docx template file` is used with `fields`, Jinja2 can now make
  changes to objects in the interview answers.

### Fixed
- Replaced `pycurl` with `requests` because it was causing problems
  for the `.from_url()` method of `DAFile`.
- Pressing Tab to navigate to the CodeMirror editor now focuses the
  editor appropriately.
- Problem with pushing to GitHub from Playground, introduced in last
  version.

## [1.5.7] - 2024-09-05

### Changed
- Migrated the text editor in the Playground and the Configuration
  from CodeMirror 5 to CodeMirror 6. Searching is now accomplished
  with Ctrl-f. Dark mode support is improved. The mixed-mode syntax
  highlighting of Python code in `code` blocks is no longer
  available. (CodeMirror 6 is a complete rewrite.) Pressing F11 for
  full-screen mode and Ctrl-space for autocomplete are still
  available.
- The `GoogleAPI` class can now be used with ARM processors.
- The "Share" button in the Playground now copies the hyperlink to the
  clipboard when you click it.

### Fixed
- The `floating label` labels are now visible on comboboxes.

## [1.5.6] - 2024-09-01

### Added
- The `auto jinja filter` option under `features`.

### Fixed
- Adapted `syslog-ng` to Ubuntu 24.04.

## [1.5.5] - 2024-08-20

### Fixed
- Adjusted for an issue with `python-docx` and/or `docxcompose`
  creating corrupt DOCX files when the DOCX template was created by
  LibreOffice.

## [1.5.4] - 2024-08-20

### Fixed
- Downgraded `uWSGI` due to issues with workers not being killed
  promptly during the restart process.

## [1.5.3] - 2024-08-18

### Fixed
- Upgraded `nltk` because version 3.8.2 was deleted from PyPI.
- Extended the wait time for server restarts to wait for all of the
  background processes to finish restarting.

## [1.5.2] - 2024-08-16

### Fixed
- Dark mode CSS visibility problem introduced by the fix in 1.5.0 that
  addressed the `focus-visible` problem.

## [1.5.1] - 2024-08-15

### Fixed
- Problem with sending email due to change in Flask-Mail.
- The effect of `sessions are unique` was changed to be more like
  the effect of `require login`.

## [1.5.0] - 2024-08-14

### Added
- The `max celery processes` Configuration directive.

### Changed
- Upgraded Python dependencies. Note that if you are using third-party
  Python packages, you may encounter dependency conflicts. Although
  these version upgrades did not require any changes to
  **docassemble** core code, it is possible that your interviews will
  need to be updated.
- Upgraded Font Awesome.
- If `ask_object_type` is used and `object_type` is also set, the
  `object_type` will be ignored.
- When converting PDF to PNG, the resolution will be what it would be
  if the long edge of each page was scaled to 11 inches.
- The `exit link` can be set to `exit_logout` in order to log the user
  out in addition to deleting the user's session.

### Fixed
- The Jinja2 `safe` filter can be used to insert content that contains
  Jinja2 templating features.
- Issue with keyboard navigation where the `focus-visible` indication
  was not appearing on radio buttons and checkboxes.
- On machines with a large number of CPU cores but limited memory, so
  many `celery` workers could be spawned that the system's memory
  could be exhausted, unless the Configuration sets a lower number of
  `celery processes`. Now, the number of `celery` workers spawned by
  default will not be greater than the number of gigabytes of total
  memory divided by two. This limit can be overridden by setting `max
  celery processes` to a different limit, or by setting `celery
  processes` to a specific number of workers.

## [1.4.112] - 2024-08-02

### Changed
- The default value of a non-`required` multiple-choice text field is
  now `''` instead of `'None'`. The default value when the field is
  not filled out is based on its `datatype`, e.g., `0` for `datatype:
  integer`. The default data type is `text`.

### Fixed
- The `rendering font` feature had been inadvertently disabled.
- Commas entered into numeric fields were causing the field not to
  validate; now any invalid characters are removed.

## [1.4.111] - 2024-07-23

### Fixed
- Word sidebar uploads did not save in the selected project.

## [1.4.110] - 2024-07-22

### Added
- The option of giving an item under `review` a `css class`.

### Changed
- The `bg-secondary-subtle` class is now used place of `bg-light`
  since it has a better appearance in dark mode.

### Fixed
- Actions in the `menu_items` were not launched using Ajax.
- If `ask_object_type` is used, the `object_type` will be set to
  `None`.
- When `hide corner interface` was used, the `navigation bar html` was
  not shown.

## [1.4.109] - 2024-07-12

### Fixed
- Bug related to Playground package generation, introduced in 1.4.108.

## [1.4.108] - 2024-07-10

### Changed
- The standard `.gitignore` can be customized with the Configuration
  directive `default gitignore`.
- When using `_use_jinja2=False`, the DOCX file is still processed for
  images and other global elements.

### Fixed
- Missing method `.age_in_months()`.
- The `get_user_info()` function returned `None` if the user was not
  logged in, even if anonymous users are given the permission to
  access user information.
- Text analysis algorithm received insufficient information when the
  `question` is represented as data.
- The `modtime` of entries created or modified by
  `store_variables_snapshot()` was inconsistent because initial
  entries used the default PostgreSQL datetime, and entries that were
  changed used `datetime.datetime.utcnow()`.
- An exception could arise in rare circumstances due to
  interview-specific settings being accessed by a function that was
  called outside of the context of a particular interview.

## [1.4.107] - 2024-06-10

### Changed
- The `attachment options` block now supports setting default
  `metadata` for attachments.
- ZIP files generated by the Packages page of the Playground contain a
  standard `.gitignore`.

### Fixed
- Problems with Google Fonts affecting Markdown document assembly
  (system upgrade required).
- Problem with form validation in the Packages folder of the
  Playground.

## [1.4.106] - 2024-06-08

### Added
- The `manual` feature of `attachment`, which allows a `DAFile` to be
  attached to an `attachment`.
- The `privileges` and `permissions` attributes of the `user_info()`
  function.
- The `request_url` attribute of `current_context()`. This returns a
  dictionary containing the elements of the URL of the currently
  executing request. Note that this URL does not always match the URL
  that the user sees in the navigation bar in the browser, because
  many requests are Ajax requests. The dictionary keys are `args`,
  `base_url`, `full_path`, `path`, `scheme`, `url`, `url_root`.
- A `__config__` variable is now available when using `# use jinja` in
  interview YAML files so that items in the Configuration are
  accessible.

### Changed
- The `validate()`, `transform()`, and `default_for()` methods of a
  `CustomDataType` are now called with a third positional parameter
  that is a dictionary containing the data attributes for the given
  field. This change is backwards-compatible, so if your method does
  not expect the additional positional parameter, it is not called
  with the additional positional parameter.

### Fixed
- In the Playground, variables representing errors defined by `except`
  statements showed up as undefined variables.
- If `# use jinja` is enabled and there were Jinja2 errors in the
  template, the Playground page could not load.

## [1.4.105] - 2024-06-01

### Changed
- The `validate()`, `transform()`, and `default_for()` methods of a
  `CustomDataType` are now called with an additional positional
  parameter that is the name of the variable as a string. This change
  is backwards-compatible, so if your method does not expect the
  additional positional parameter, it is not called with the
  additional positional parameter.
- When using a `datatype` that references a `CustomDataType`, `data`
  attributes will be added to the `<input>` element containing the
  values of field modifiers `minlength`, `maxlength`, `min`, `max`,
  `step`, `scale`, `currency symbol`, and `field metadata`, if those
  modifiers are present. The `field metadata` are available as a JSON
  string in the `field-metadata` data attribute.
### Fixed
- Bug that prevented the Configuration directive `initial dict` from
  functioning.
- Added `aria-required` and moved `role="radiogroup"` for
  accessibility compliance.
- Bug with `button style` Configuration parameter.

## [1.4.104] - 2024-05-06

### Changed
- Changes to HTML for accessibility purposes.
- Upgraded Bootstrap to version 5.3.3, jQuery to version 3.7.1, Font
  Awesome to verson 6.5.2, and Pillow to version 10.3.0.
- Upgraded Ubuntu to 24.04 and Pandoc to version 3.1.13 (system
  upgrade required).

### Fixed
- Bug with `progress bar multiplier`.
- CSS error with radio buttons and labels above fields.

## [1.4.103] - 2024-04-29

### Added
- Interface in the Word sidebar for changing the Playground project.
- Additional language functions accessible through methods on standard
  classes.
- `attachment` object of the result of `current_context()` containing
  information about the attachment currently being assembled.

### Changed
- Changes to HTML for accessibility purposes.

### Fixed
- PostgreSQL error in multiserver configuration when two servers try
  to delete a package at the same time.
- The `ask_object` feature did not work when `new_object_type` was
  used with `.using()`.

## [1.4.102] - 2024-03-18

### Fixed
- Bug with `ip address ban enabled`.

## [1.4.101] - 2024-03-15

### Added
- The `noun_is_singular` keyword parameter to the `noun_plural()`
  function.

### Changed
- The `date_difference()` function's `describe()` method will now
  describe times.
- In error messages from YAML parsing, fall back to displaying YAML
  with `repr()` if displaying the YAML as YAML fails.

### Fixed
- Bug with `ip address ban enabled`.
- Bug with displaying interview logic history.

## [1.4.100] - 2024-03-07

### Fixed
- Problems with comboboxes and `disable others`.
- Problem with TIFF to PDF conversion not using compression.
- Problem with `show if` when comparing a `variable` to the empty
  string.
- An empty `js show if` caused the field not to be shown, instead of
  being ignored.

## [1.4.99] - 2024-03-02

### Changed
- `DAWeb` no longer requires the `data` parameter to be a dictionary;
  it will pass the `data` parameter directly to `requests`.
- Upgraded `redis`, `celery`, `aiohttp`, and `Pillow`.

## [1.4.98] - 2024-02-29
### Fixed
- Issue with one of the fixes in 1.4.97.

## [1.4.97] - 2024-02-29

### Added
- The `pdftk` option under `attachment` and `features` for filling in
  `pdf template file` attachments using pdftk instead of pikepdf.
### Changed
- During the Docker image build process, `pandoc` will run once, so
  that the first user to assemble a document with `pandoc` will not
  experience slowness due to LaTeX needing to generate files.
- Appearance streams will be generated when using `pdf template file`.
- Error messages related to problems in the source code will no longer
  be displayed to the user unless the user is an administrator or
  developer. If you want these error messages to appear to all users,
  set `debug: True` and `development site is protected: True` in the
  Configuration. The error messages will be available in
  `docassemble.log`.
### Fixed
- Fixed security issue identified by Riyush Ghimire, affecting
  versions 1.4.53 to 1.4.96, that could cause contents of files in the
  filesystem to be revealed. This is a high severity issue and
  upgrading as soon as possible is recommended.
- Fixed security issue identified by Riyush Ghimire, affecting
  versions up to 1.4.96, that allowed an open redirect URL to be formed.
- Fixed security issue identified by Riyush Ghimire, affecting
  versions up to 1.4.96, that would allow HTML or JavaScript
  injection.

## [1.4.96] - 2024-02-14

### Fixed
- Issue with installation of SSL certificates stored on S3.

## [1.4.95] - 2024-02-04

### Fixed
- The `small screen navigation` option under `features` could not be
  overridden to `True`.
- The `nice_number()` function sometimes did not properly detect
  whether a number was an integer.

## [1.4.94] - 2024-01-23

### Added
- The `raw html` special field type under `fields` and `review`. This
  is similar to `html` but allows modification of the structure of the
  HTML in the list as a whole.

## [1.4.93] - 2024-01-20

### Added
- The `current_context()` function, which is the new function to use
  in place of `user_info()` for attributes that are not related to the
  logged in user. The object returned by `current_context()` also has
  a new attribute, `inside_of`, which can be used to detect whether
  the Python code that is currently executing is executing inside of a
  particular type of document assembly process.

### Changed
- The `user_info()` function had previously provided much of the
  information that the `current_context()` function now
  provides. However, the name `user_info()` was not suitable for that
  information. A deprecation warning will be logged if code accesses
  the attributes of `user_info()` that do not relate to the logged-in
  user. In a future version, accessing these attributes will raise an
  exception.
- The behavior of the object returned from `user_info()` is different,
  which might be a breaking change if you used `user_info()` in a
  certain way. Previously, `user_info()` returned an object with
  static attributes. Now, the attributes of the object returned by
  `user_info()` are dynamic attributes (using the `@property`
  decorator). If you set `u = user_info()` and `u` becomes a variable
  in the interview answers, `u.id` will always return the user id of
  the current logged-in user, not necessarily the user who was logged
  in when `u` was defined.
- The new function `current_context()` works the same way. If you set
  `c = current_context()` then `c.current_section` will be the current
  section at the time the attribute was accessed, not the time that
  `c` was defined.
- Another difference in the way that `user_info()` operates is that if
  the user is not logged in, the attributes other than `first_name`
  and `last_name` will exist, but will be `None`. Previously, those
  attributes did not exist, and accessing them would raise an
  `AttributeError`. If you want to test whether the user is logged in,
  use `user_logged_in()`.

### Fixed
- A non-`required` boolean field value that was not filled out was set
  to `False` instead of `None` as the documentation specified. The
  default value is now `None`.
- The `words` directive was unable to load translations from
  Playground packages.

## [1.4.92] - 2024-01-17

### Fixed
- The `reconsider` and `need` modifiers were not active on all
  `mandatory` blocks.
- The `depends on` and `on change` features did not work on all `code`
  blocks executed during `process_action()`.
- Playground raised exception if `playground examples` is an empty
  list.

## [1.4.91] - 2024-01-07

### Changed
- Improved error messages when Python code contains errors.

### Fixed
- Error when YAML parsing did not succeed.

## [1.4.90] - 2024-01-05

### Fixed
- Error when YAML parsing did not succeed.

## [1.4.89] - 2023-12-23

### Added
- The `invite_user()` function.

### Changed
- Upgraded dependencies.
- The `/api/user/<user_id>` PATCH endpoint now allows changing whether
  the user is `active`.
- Changed the background color of the signature canvas to grey when
  dark mode is in effect.

## [1.4.88] - 2023-12-03

### Changed
- When `min` or `max` is used with a `datatype: date` or `datatype:
  datetime`, the minimum and/or maximum are now indicated in the HTML
  so that browser widgets know what they are.
- When the browser uses dark mode, the red asterisk is less bright.
- When `grid` is used, items are aligned to the bottom of the row.

### Fixed
- Bug in `/api/playground_install`.
- Fixed formatting in `grid` mode when label is empty.
- When browsing other users' playgrounds, the Download and GitHub
  buttons in the Packages folder did not work as intended.

## [1.4.87] - 2023-11-28

### Changed
- Set a specific maximum number of open file descriptors (1048576) to
  avoid problems with `ulimit -n` being too high on some kernels
  (system update required).

## [1.4.86] - 2023-11-26

### Added
- The `disabled` field modifier for showing a field on the screen that
  is always disabled.
- The `under text` field modifier for showing help text under a form
  field in a smaller font.
- The `item grid` field modifier, which is similar to the `grid`
  modifier, but affects whether the choices in a list of radio buttons
  or checkboxes wrap.
- The `developer can install` Configuration directive.
- The `debug startup process` Configuration directive for logging the
  timing of the different parts of the `uwsgi` loading process.
- The `current_section` attribute of the output of `user_info()`.
- The `owner password` option under `attachment` for protecting a PDF
  file with an owner password.
- Support for login using Zitadel.

### Changed
- The CSS for `<code>` elements no longer collapses spaces.

### Fixed
- The UI of fields with `datatype: range` were not shown as disabled
  even if the underlying `<input>` was disabled.
- Sync and Run did not work correctly in some browsers because of a
  JavaScript timing issue.
- Module files in zipped packages were not detected unless a root
  directory was used.

## [1.4.85] - 2023-11-02

### Added
- The `run oauthlib on http` Configuration directive. You may need to
  set this to `True` if you use the `oauthlib` library on a server
  that uses `http://` instead of `https://`.

### Fixed
- If integration with GitHub goes wrong, the user could continue to
  see errors after correcting the configuration.

## [1.4.84] - 2023-10-26

### Fixed
- An incorrect `instanceName` was used when a variable name in an
  `objects`, `objects from file` or `data` block contained an iterator
  variable.

## [1.4.83] - 2023-10-25

### Added
- The `default rendering font` Configuration directive. This allows
  you to specify a system-wide font that should be used for rendering
  form fields when using an `attachment` with `pdf template file` and
  `editable: False`.

### Changed
- The feature from 1.4.79, described below as "`pdftk` will render
  form fields to text using the `msttcorefonts` version of Arial,
  which has better support for Unicode characters," has been removed
  because with this font, `pdftk` rendered text too small when the
  font size in the field was "Auto." To reenable this feature, specify
  a `default rendering font` in your Configuration, or specify a
  `rendering font` with each attachment.

### Fixed
- Error when non-`str` values are used as `datatype: checkboxes`
  values.
- The `css class` of a `question` persisted after the Continue button
  was pressed.

## [1.4.82] - 2023-10-15

### Changed
- Selected dependencies upgraded.
- Users whose accounts are made inactive will be immediately logged
  out.
- When a relative file reference is given to `bootstrap theme` in
  `features`, the reference will be resolved using the package in
  which the immediate YAML file is located, rather than the package of
  the main interview file.
- The `docassemble.webapp` package now depends on `certbot`,
  `certbot-apache`, `certbot-nginx`, and `acme`, even though it does
  not use these packages. This is because upgrades to
  `docassemble.webapp` may upgrade dependencies of `certbot` and cause
  `certbot` to fail.

### Fixed
- The web server that responds while docassemble is starting up no
  longer returns 404 errors (system upgrade required).
- Incorrect input validation of email field when editing profile of a
  user who uses the phone-based login method.

## [1.4.81] - 2023-10-03

### Fixed
- Test for appropriate system version before using a `rendering font`.

### Changed
- Added clipboard button next to API key.
- Avoid exceptions when invalid values are passed to `ordinal()` and
  `ordinal_number()`.

## [1.4.80] - 2023-10-01

### Changed
- Added error message if more than one of `show if`, `hide if`,
  `disable if`, or `enable if` is used on the same field. The only
  situation in which these can be combined on a single field is if one
  is using the `code` form and the other is not.

### Fixed
- Inefficient JavaScript for handling nested `show if` field
  modifiers.
- The input validation error message for entering a non-number did not
  appear if the validation failed on the regular expression pattern.

## [1.4.79] - 2023-09-18

### Added
- The `rendering font` option to `attachment`.

### Changed
- `pdftk` will render form fields to text using the `msttcorefonts`
  version of Arial, which has better support for Unicode characters.
- Updated the collection of Material Icons.

### Fixed
- Exception raised in certain circumstances when using `depends on`.
- When `hide corner interface` was used, on small screens the toggler
  still showed.

## [1.4.78] - 2023-09-16

### Added
- The `pen color` modifier for the `signature` block.
- The `file css class` field modifier for `datatype: file` and
  `datatype: files` fields. This can be set to `None` to disable the
  Bootstrap File Input plugin for the file upload input element.

### Fixed
- Errors with the Apache web server option (system upgrade required).
- Error with `js show if` when used in conjunction with `grid`.

## [1.4.77] - 2023-09-10

### Added
- The `hide continue button` and `disable continue button` modifiers
  for `question`.
- The `offset` option for the `grid` field modifier for inserting
  horizontal space before a field.

### Fixed
- Error when calling `.privilege_access()` on a `DAFile`.
- Error when using social logins.

## [1.4.76] - 2023-09-09

### Added
- The `grid` field modifier for displaying fields side-by-side in a
  responsive flexbox.
- The `tabular` modifier for the `review` block, which will cause the
  items to be displayed in an HTML `<table>`.
- The `abbreviate` optional keyword parameter of the `states_list()` function.

### Changed
- Altered the CSS of `radio`, `yesno`, `yesnowide`, and `checkboxes`
  labels so that the text will not wrap under the bullet.
- Configuration will not save if there are duplicate keys in the YAML.

### Fixed
- Avoided `KeyError` when combining `terms` and `autoterms`.

## [1.4.75] - 2023-09-05

- No changes, version advanced by accident.

## [1.4.74] - 2023-09-05

### Fixed
- Bug with `datatype: object`.

## [1.4.73] - 2023-09-04

### Added
- The `gotenberg url` Configuration directive, which allows for the
  use of an external Gotenberg server for DOCX to PDF
  conversion.
- The Docker environment variable `SUPERVISORLOGLEVEL`, which can be
  set to `debug` so that application log messages can be viewed with
  `docker logs` (system upgrade required).

### Changed
- Additional fonts are installed in the operating system to support
  a greater variety of languages (system upgrade required).
- Upgraded pdftk and Pandoc (system upgrade required).
- Disabled autocomplete on login and register pages.
- The `DAFileList` is now initialized with the `complete_attribute`
  set to `initialized` and the `object_type` of `DAFile`.

### Fixed
- Issue with JSON representation of the question when fields were
  generated by code.
- When using Keycloak, logging out resulted in an error message due to
  a change in the Keycloak code.

## [1.4.72] - 2023-08-23

### Changed
- The pseudo-fields `favorite_fruit[nota]` and `favorite_fruit[aota]`
  referring to the "None of the above" and "All of the above"
  checkboxes in a `datatype: checkboxes` field can now be used in a
  boolean `show if`.

## [1.4.71] - 2023-08-22

### Changed
- The `val()`, `getField()`, and `setField()` JavaScript functions can
  references pseudo-fields `favorite_fruit[nota]` and
  `favorite_fruit[aota]` to refer to the "None of the above" and "All
  of the above" checkboxes in a `datatype: checkboxes` field.

### Fixed
- Bug introduced in 1.4.70 relating to GitHub URLs.

## [1.4.70] - 2023-08-20

### Changed
- When installing a package with a GitHub URL, the
  `#egg=mypackagename` feature of GitHub URLs is now respected, and
  the name of the package will be extracted from `#egg` instead of
  from the GitHub repository name.
- Grouped the `initialize`, `postgres`, and `redis` Supervisor
  processes into a group called `main` so that they shut down
  simultaneously rather than sequentially.

### Fixed
- The `js show if` feature did not work correctly when an expression
  reference two different fields.
- The `auto terms` and `terms` features interfered with each other
  when the same term was referenced in each.
- Bug in locale-setting code.
- The system for forcing the admin user to change their password when
  the password is `password` introduced unnecessary delay on page
  loads.
- The "Please wait while docassemble starts . . ." page would refresh
  into an error rather than refresh into the default interview under
  some conditions.

## [1.4.69] - 2023-08-15

### Fixed
- The `val()` JavaScript function erroneously returned encoded values
  for `datatype: object` and `datatype: object_radio` fields. The
  function has been modified so that it returns the `instanceName` of
  the selected object.
- The combobox HTML did not set an `aria-label`.
- Markdown-to-HTML conversion in popover `help` text was not
  full-featured.

## [1.4.68] - 2023-08-10

### Changed
- The `ldap login` feature now supports TLS and anonymous binding.

### Fixed
- Error with exporting tables to Excel, caused by the upgrade of the
  Pandas dependency.
- The way that locale-related functions actually worked did not match
  the way they were documented; they have been fixed so that they
  match the way they are documented. The `update_locale()` function is
  also now imported by default.
- Bug with handling of non-required object fields that are not
  answered.

## [1.4.67] - 2023-07-28

### Changed
- Upgraded `webdriver_manager`.
- The `.delete()` method of `DAGlobal` will now exit silently if
  called on a `DAGlobal` object that has already been deleted.

## [1.4.66] - 2023-07-24

### Changed
- Upgraded dependencies. Packages that might require code changes
  include `selenium` (now at version 4) and `matplotlib` (see the
  "Generating a graph and inserting it into a document" recipe). Due
  to incompatibilities with the latest version of `markdown`, the
  `mdx_smartypants` extension is no longer being used. Instead the
  standard `smarty` extension is used. There are some differences
  between the two extensions, such as the transformation of ellipses.

### Fixed
- Adapted code so no error will be raised if docassemble tries to
  create a directory where one already exists. A race condition of
  some sort seemed to be causing such errors for some users.

## [1.4.65] - 2023-07-13

### Fixed
- The `navigation: horizontal` feature was not functional.

## [1.4.64] - 2023-07-11

### Fixed
- Issue with the `NameError` exception change in 1.4.63.

## [1.4.63] - 2023-07-02

### Changed
- If a `NameError` exception arises out of code in a module file,
  **docassemble** will raise an exception instead of treating the
  exception as a reference to an undefined variable.

### Fixed
- Issue with using `default admin account` to set a default API key if
  an external Redis server is not being used (requires system
  upgrade).

## [1.4.62] - 2023-06-21

### Fixed
- Issue with administrative interviews not appearing in the menu.
- Issue with unchecked checkbox fields subject to a `show if` not
  being located for purposes of placing an error message.
- Issue with failing to process false values of `object_checkboxes`.

## [1.4.61] - 2023-06-18

### Fixed
- Issues with the timing of `change` event triggers on the combobox.

## [1.4.60] - 2023-06-17

### Fixed
- Bug with `datatype: raw`.

## [1.4.59] - 2023-06-12

### Fixed
- Adapted the fix made in 1.4.58 to work correctly with objects with
  random instance names.

## [1.4.58] - 2023-06-10

### Added
- The optional keyword argument `evaluate` of `force_ask()`.

### Changed
- The CSS of `signature` screens was changed so that the compact mode
  only takes effect if the screen is small and has a landscape
  orientation.

### Fixed
- The `value()` function (which is used by `reconsider()` and the
  `reconsider` modifier) did not raise the correct undefined variable
  exceptions when the variable name included variable aliases. The
  code was fixed so that the exceptions raised correspond with the
  exceptions that would be raised if the expression was evaluated by
  Python. It is possible that interview logic in existing interviews
  may rely upon the quirks of the previous version of the code, so it
  is important (as it always is) to test interviews before deploying
  this version in production.
- The JSON representation of a `question` did not show fields that
  were generated by `code`.
- Error with the `rtf to docx` file type.
- The `instanceName` of a `DAFileCollection` object generated by an
  `attachment` or `attachments` block was set to the literal `variable
  name` without interpolation of variables.

## [1.4.57] - 2023-06-05

### Fixed
- Modified the change that 1.4.56 made to `force_ask()` and
  `reconsider()` to work better with objects with random instance
  names.

## [1.4.56] - 2023-06-04

### Added
- The `hide corner interface` option under `features`.

### Changed
- The `administrative interviews` Configuration directive now accepts
  items that add custom URLs to the menu.
- `force_ask()` or `reconsider()` will now attempt to act on the
  intrinsic name of the referenced variable rather than the literal
  string passed to the function.
- The functions `format_date()`, `format_datetime()`, `format_time()`,
  `month_of()`, `year_of()`, `day_of()`, `dow_of()`, `qr_code()` are
  now available as Jinja2 filters.
- The JavaScript functions `var()`, `getField()`, `setField()`, and
  `getFields()` were modified to work better with multiple choice
  fields. `getField()` now returns the `<fieldset>` parent element
  rather than the first input element. `val()` will return an array of
  answers for a checkbox or multiselect. Object-based fields use
  instance names as values.

### Fixed
- Items under `administrative interviews` will now appear for users
  who are not logged in if the permissions allow anonymous users to
  see the item.
- When a `datatype: checkboxes` field has `required: False`, the "None
  of the above" selection does not need to be selected.

## [1.4.55] - 2023-05-21

### Fixed
- Issue with the "Run" button in the variables sidebar in the
  Playground, introduced by the upgrade of Flask in 1.4.52.

## [1.4.54] - 2023-05-21

### Fixed
- Updated `setup.py` to require Python 3.10. Version 1.4.53 has been
  deleted from PyPI so that users with Python 3.8 cannot upgrade past
  1.4.52.

## [1.4.53] - 2023-05-21

### Added
- The `delete` keyword parameter to `set_session_variables()`.

### Changed
- Use `importlib.resources` instead of `pkg_resources`.

## [1.4.52] - 2023-05-17

### Changed
- Upgraded Flask.
- `depends on` will now invalidate dependencies.

### Fixed
- Allow use of True and False as radio button values in `pdf template
  file` document assembly.
- Allow `_use_jinja2` in `include_docx_template()`.

## [1.4.51] - 2023-05-08

## [1.4.50] - 2023-05-08

### Fixed

  still running.

## [1.4.48] - 2023-05-05

### Fixed

- Issue with Playground variable parser.

## [1.4.47] - 2023-04-29

  `all_variables(special='title')` now correspond with the names used
  to set the values (with backward compatibility).
- Preserve capitalization when conjugating verbs.
- Upgrade `reportlab`, `docxtpl`, and `pikepdf` dependencies.

### Fixed
- Issue with file inputs not enabling and disabling.
- Bug that caused wrong exception to be raised if DOCX to PDF
  conversion failed.
- Replaced `description-file` with `description_file` in `setup.cfg`.
- Error with `/restart_session` endpoint when user not logged in.

## [1.4.46] - 2023-04-19

### Changed
- Added `all` and `any` as Jinja2 filters.

### Fixed
- Issue with placement of server-side validation messages when a
  custom data type has a `show if`.

## [1.4.45] - 2023-04-14

### Changed
- Failure to convert DOCX to PDF will raise an Exception.

### Fixed
- JavaScript issue with the "None of the above" checkboxes when
  choice-specific `help` is applied to a checkbox choice.

## [1.4.44] - 2023-04-09

### Added
- The `bearer` authentication option for `DAWeb`.
- The `sheets_service()` method of `DAGoogleAPI`.
- Google Fonts (system upgrade required).

### Changed
- Package versions in the Packages folder of the Playground must be
  valid Python version numbers.
- Upgraded `cryptography`, `redis`, and `pikepdf`.
- Upgraded Pandoc (system upgrade required).

### Fixed
- Issue with rotation of `supervisord.log`.

## [1.4.42] - 2023-03-19

### Added
- The `revoke()` method of the object returned from
  `background_action()`.

### Changed
- When listing choices in a multiple choice question, you can use
  `show if` to conditionally include the choice in the list of
  choices.

## [1.4.41] - 2023-03-14

### Changed
- The `check in` feature now sends two additional action arguments,
  `_changed` and `_initial`. These arguments are not reported by
  `action_arguments()` but can be retrieved with `action_argument()`.
- The `defined()`, `value()`, and `showifdef()` functions now accept a
  keyword argument `prior` which can be set to `True` in order to
  correctly handle situations where the user has just clicked the Back
  button and it is necessary to know the value that a variable had
  prior to the user pressing the Back button. If `prior` is `True`,
  the set of interview answers that was just discarded will be
  accessed first, and then the current interview answers will be
  accessed. In situations where the user has not just pressed the Back
  button, setting `prior` to `True` has no effect.
- The `countries_list()` and `states_list()` functions now return
  alphabetically sorted results. `states_list()` returns an empty
  dictionary when the `country_code` is invalid.
- When the second argument of `background_response()` is `'fields'`,
  and the first argument is a dictionary of variable names and values,
  the value of a dropdown field can be set to a dictionary with keys
  `value` and `choices`. The `choices` will replace the options in the
  dropdown for that field.

### Fixed
- Upgraded `pikepdf` and fixed issue with way it is called.

## [1.4.40] - 2023-03-07

### Changed
- The `analytics id` subdirective of `google` can refer to a list of
  IDs, all of which will be configured.

  "state" abbreviations.
- Cursor was not pointer over combobox drop-down items.
- Better handling of radio buttons in PDF files.

  jQuery Validation Plugin.

## [1.4.38] - 2023-02-20

## [1.4.33] - 2023-02-05

### Changed
- Updated Python and JavaScript dependencies.
- Upgraded Bootstrap to version 5.3.
- Added support for using `min` and `max` with `datatype: time` and
  `datatype: datetime`.
- The `data` and `data from code` blocks can be used with an `objects:
  objects` modifier, which will cause the data structure to be
  interpreted in the manner of `objects_from_file()`. A `gathered`
  modifier is also supported.
- `continue button field` can now be used with `buttons` where one of
  the items under `buttons` is `continue`.
- The Configuration directive `mail` now accepts a list of
  configurations, and `send_mail()` now accepts a `config` keyword
  parameter.
### Fixed
- Removed code that transformed `\\_` into `__` in Markdown.
- Ensured that dropdown options are free of HTML.
- Default values of object-based fields did not appear in all
  circumstances.
- The `editable: False` option for `pdf template file` now shows
  better formatting of fields.

## [1.4.32] - 2023-01-28

### Fixed
- Bug in 1.4.31.

## [1.4.31] - 2023-01-28

### Added
- The `all of the above` and `check others` modifiers for checkbox
  fields.
- The `celery modules` Configuration directive.
- Recipe for calling background tasks from Flask endpoints.
### Changed
- When setting up two factor authentication with the authenticator
  app, a code is shown in addition to a QR code.
- The way that `objects from file` works has changed; it is no longer
  treated as a `mandatory` block, but instead acts like an `objects`
  block that is called upon when a variable is needed.

## [1.4.30] - 2023-01-23

### Fixed
- Scrolling issue when moving from one screen to another.
- JavaScript bug.

## [1.4.29] - 2023-01-20

### Fixed
- Follow-up fix to 1.4.28 change regarding unicode values in

### Fixed
- Rolling backup files on S3 were copied to the wrong directory during

- The question modifiers `continue button color` and `resume button
  color`.
- Additional options `labelauty` and `labelauty nota` under the
  `button colors` Configuration directive.
### Changed
- Items in multiple choice lists, when expressed as a dictionary, can
  now include keys `css class` and `color`. The HTML element for the
  item will have the `css class` as a CSS class. The `color` is
  expected to be a Bootstrap color name. This will change the
  background color of the HTML element, unless the element is an
  `<option>` element. The `css class` and `color` keys have no effect
  on combobox items.
- Buttons in `action buttons` can be modified with a `css class`.

## [1.4.22] - 2022-12-08

### Fixed
- Changed NGINX configuration so that requests for hostnames other
  than `external hostname` are redirected.
- Changed `list collect` behavior to prevent reaching circularity
  limit when quantity of items is very large.
- Issue with validation code on file fields with `show if`.

## [1.4.16] - 2022-11-01

### Fixed
- Issue with alembic not running properly during restart.

## [1.4.15] - 2022-10-31

### Fixed
- Problem with `authorized registration domains`.

## [1.4.14] - 2022-10-25

### Fixed
- Additional fix to allow the use of `table prefix` in `db`.

## [1.4.13] - 2022-10-24

  `variables_as_json()`, and `all_variables()` now controls whether
  the `nav` variable is included in the output.
- The `authorized registration domains` Configuration directive now
  applies to social login methods as well as username/password login.
- Increased accessibility of the `datatype: combobox` interface.
### Fixed
- Problem with the exim4 mail configuration.

- Issue with exim4's overinclusive `dc_other_hostnames` setting.
- Error with images in Markdown to DOCX conversion.
- Error with `overlay_pdf()`.
- Error with `temporary session` when user is not logged in.

## [1.4.9] - 2022-09-10

### Added
- The `voices` option of the `voicerss` Configuration.
- The `voice` keyword parameter of the `set_language()` function.
- The `auto login` Configuration directive.
- The `output_to` keyword parameter of the `.convert_to()` method of `DAFile`.

  `docx_concatenate()`, `zip_file()`, `overlay_pdf()`.
- The `extract_pages()` method of `DAFile`.
### Changed
- If an attempt is made to access the contents of a `DAFile` that is
  not yet initialized, the `.initialized` attribute will be
  sought. The `.initialize()` method sets `.initialized` to
  `True`. Thus, if you have a `code` block that calls `.initialize()`
  on a `DAFile` called `myfile`, you can attach `sets:
  myfile.initialized` to the `code` block and it will be called upon
  if the interview logic requires the contents of `myfile`.
- When an `attachment` that has a `name` creates a `DAFileCollection`
  object, the `DAFile` attributes will have their `alt_text` set to
  the `name` followed by the file type in parentheses.

- The `root owned` Configuration directive.
- Support in the Kubernetes implementation for using a read-only file
  system where all Configuration changes and package updates take
  place using Docker images and the only directories on the server
  that are writable are directories for storing runtime information
  (e.g. PID files) or log files.
- The `ip address ban enabled` Configuration directive.
- The `old_password` parameter for `set_user_info()` and the API
  endpoints for changing user information, so that the user's
  encrypted data can be migrated.
- The `transform_json_variables()` function.
- Support for server-side encryption when using S3.
### Changed
- In the Docker container, the operating system is upgraded to Ubuntu
  22.04 LTS and Python is upgraded to 3.10.
- `aloe` is no longer a required package. It has a dependency, `nose`,
  that is not compatible with Python 3.10. Instead, `behave` is now a
  required package.
- Switched to the Azure CLI for managing files in Azure Blob Storage
  from shell scripts.
- A restart (e.g., saving the Configuration, installing a package)
  will erase any IP address bans caused by failed login attempts.
- The API endpoints for changing information about existing users now
  work with `PATCH` as well as `POST`.
### Fixed
- Links in dropdown navigation menu for mobile devices were not
  clickable.
- The `session` parameter of `/api/resume_url` was not working (it was
  expecting `session_id`.
- Optimized `interview_list` for cases where `action='delete_all'` and
  `query` are used together.
- Unnecessary transmittal of background task result to web browser
  when the `refresh` option of `background_action()` is used.
- Migration of encrypted `DAStore` objects when password is changed.
- The `set_parts()` function did not support all of the screen parts.

## [1.3.49] - 2022-06-09

### Added
- Example interviews relating to inserting graphs and cards.
### Changed
- Changed the name of the `explanation()` function to
  `logic_explanation()`. NOTE THAT THIS IS A BREAKING CHANGE. However,
  you are most likely not using the `explanation()` function, so this
  probably will not matter.
### Fixed
- Cleared spurious syslog-ng error message.
- Error getting the data format of a question when `debug` is false.

## [1.3.48] - 2022-06-05

  `url_action()`, `action_call()`, and `action_perform()`.
- The `logoutpage` Configuration directive.
- The `allow changing password` directive.
### Changed

- The `interview_url()` and `url_of('interview')` functions now accept
  unqualified `i` parameters, which will be interpreted as references
  to interview files in the current package.
### Fixed
- The HTML version of the error notification e-mail lacked some of the
  information in the plain text version.
- The `next` parameter of `url_of()` was not functional for `leave`,
  `logout`, `exit`, and `exit_logout`.

### Fixed
- When a `yesnoradio` or `yesnomaybe` field is not `required` and is

  `False`. THIS MAY BE A BREAKING CHANGE FOR YOU if you relied on
  variables being set to `False` when the user did not provide a value
  for a `yesnoradio` or `yesnomaybe` field. The documentation for
  `required` has always stated that the variable will be set to `None`
  if the user does not provide a value, so this change brings the code
  into line with the documentation.

  triggered.

  `docassemble.base.util`'s names.

### Changed
- If the database is PostgreSQL, the Alembic table alteration
  introduced in 0.5.97 for MySQL compatibility purposes is no longer
  applied by default because it might take too much time on a server
  with a large SQL database.  The discrepancy between the SQLAlchemy
  column type specification (varchar) and the actual PostgreSQL column
  types (text) is harmless.  If your SQL database is not large, you
  can set `force text to varchar upgrade: True` in your Configuration
  before upgrading to force the column type alteration to take place
  during the upgrade.  After upgrading to 0.5.105+, you can remove
  `force text to varchar upgrade` from the Configuration.  This is
  only applicable if upgrading from 0.5.96 or before; if you already
  upgraded to 0.5.97 - 0.5.104, then the alteration has already taken
  place.

  For the old behavior, set `allow embedding: True` in the
  Configuration.

## [0.5.101] - 2020-02-23
### Changed
- Playground syntax highlighting now highlights Python code as Python
  code.

  You can still set a literal `group_id` using the keyword parameter
  `group_id`.

  colon, if any, removed), the array corresponding to that key will be
  used.
