# Changelog All notable changes to the CoolAdmin Bootstrap 5 Admin Dashboard Template will be documented in this file. The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). ## [3.3.0] - 2026-05-22 ### Renamed `theme-2026` → `app` The "modern overlay" stylesheet picked up a year-flavoured name in v3.1 (`theme-2026.css`). Renamed it to a neutral convention so it doesn't feel dated within months. End-user visual output is unchanged; the rebuilt CSS is byte-equivalent modulo the class-name swap. ### Changed - **`css/theme-2026.css` → `css/app.css`**, **`src/scss/theme-2026.scss` → `src/scss/app.scss`**, **`src/scss/2026/` → `src/scss/app/`** (all 36 partials). - **`body.theme-2026` → `body.app`** across all 35 pages. Every internal SCSS scope (`body.theme-2026 .m-card`, etc.) updated. Theme-preset selectors (`body.theme-2026.theme-purple` and friends) updated to `body.app.theme-purple`. - **`js/main-vanilla.js`** — `initThemeSwitcher()` gate updated to `body.classList.contains('app')`. - **`scripts/migrate-page.js`** — auto-detects `app auth-page` / `app error-page` body class (the previous strings are no longer present in any page). - **`package.json` npm scripts** — `sass --watch src/scss/theme-2026.scss:css/theme-2026.css` → `…app.scss:css/app.css`. - **`src/pug/partials/_head.pug`** — `link(href='css/theme-2026.css')` → `link(href='css/app.css')`. - **`src/pug/layouts/_default.pug`** — `body.theme-2026` → `body.app`. `_auth.pug` and `_error.pug` default `bodyClass` updated. 6 explicit-bodyClass pages (login, register, forget-pass, 404, 500, maintenance) updated. - **`src/pug/partials/content/docs.html`** — user-facing docs updated to reference `app.css` / `body.app` / `body.app.theme-purple` recipes. - **CLAUDE.md, README.md** current-tense references updated. Historical entries for v3.0 / v3.1 / v3.2 in this CHANGELOG were left as-is for fidelity to what was true at the time. --- ## [3.2.0] - 2026-05-22 ### Source pipeline — Pug templates, SCSS partials, Vite dev server Refactored the source tree so contributors can edit shared partials once instead of editing every page. Built artifacts (HTML + CSS) still ship in the repo root unchanged, so end users who clone and open `index.html` still need zero Node toolchain. Addresses [issue #35](https://github.com/puikinsh/CoolAdmin/issues/35). ### Added - **Pug templating.** `src/pug/` houses layouts (`_default.pug`, `_auth.pug`), partials (`_head.pug` mixin, `sidebar.pug`, `header-desktop.pug`, `header-mobile.pug`, `footer-scripts.pug`), and per-page files (`pages/*.pug`). The desktop sidebar and mobile nav both read from a single source-of-truth array in `_nav-data.pug` — editing one file updates the menu on every page. - **SCSS sources, split into ITCSS partials.** `src/scss/theme.scss` is an entry file that `@use`s 20 partials (`_variables`, `_generic`, `_elements`, `_objects`, fourteen under `components/`, `_utilities`, `_modern-additions`). `src/scss/theme-2026.scss` `@use`s 36 partials under `src/scss/2026/`. Sass compiles back to `css/theme.css` and `css/theme-2026.css` that is byte-for-byte semantically equivalent to the pre-refactor CSS (verified via minified diff = 0 bytes). - **Build tooling.** `package.json` with `npm run dev` (concurrent pug-watch + sass-watch + Vite dev server with HMR at `:3000`), `npm run build` (production build), and individual `build:pug` / `build:sass` scripts. `scripts/build-pug.js` is a small Node script that walks `src/pug/pages/*.pug` and renders each to a root-level `.html` file. - **Vite dev server.** `vite.config.js` configured for multi-page mode with HMR for HTML/CSS changes. ### Changed - **Three pages migrated to Pug as a proof-of-concept:** `index.html`, `login.html`, `table.html`. The Pug page files (`src/pug/pages/*.pug`) `extends` a layout and set `block variables` (page metadata + `activePage` for sidebar highlighting). Per-page inner content is currently `include`d as raw HTML from `src/pug/partials/content/` so each page can be converted to proper Pug incrementally. - **Generator meta bumped to `CoolAdmin 3.2.0`** across all 35 HTML files. - **HTML output formatting** is normalized by Pug (2-space indent, self-closing void elements) and CSS formatting normalized by sass; the regenerated files have different whitespace from the previous hand-written versions but render identically. ### Notes - The remaining 21 pages still ship as hand-written HTML at the repo root, each ~10 lines of Pug away from being source-driven. Migrating each one is a per-file extraction of its inner content into `src/pug/partials/content/` plus a small `src/pug/pages/*.pug` wrapper. - `@use` order in the entry SCSS files matches the original document order so the cascade — including the 2026 overlay's deliberately-layered "FINAL"/"ULTRA-FINAL" mobile-topbar overrides — is preserved. - `.gitignore` updated to exclude `node_modules/`, `.vite/`, and `dist/`. --- ## [3.1.0] - 2026-05-07 ### Modern theme overlay (`theme-2026.css`), 11 new pages, interactive utilities A second pass on top of 3.0 turned the template from "audited and clean" into "modern application shell". Single overlay stylesheet (`theme-2026.css`, ~7100 lines) layers an Inter + brand-blue design system on top of the legacy CSS, so the original styles still work for anyone who needs them. ### Added - **Design system overlay (`theme-2026.css`).** Activated by ``. Inter font (rsms.me CDN), brand palette tokens (`--m-c1` blue / `--m-c2` teal / `--m-c3` orange / `--m-c4` pink), surface/border/text/shadow custom properties, modern card pattern (`.m-card`), modern button pattern (`.m-btn`), stat-card, profile-card, cover-card, pricing-card, notice-card, rank-list with inline progress bars, kanban-board, project-list, deadline-list, team-list, email-list, inbox-split. - **6-preset color theme switcher.** `Cmd/Ctrl+Shift+T` cycles between Default Blue, Indigo, Emerald, Sunset, Rose, Slate. Choice persists in `localStorage`. Implemented in `initThemeSwitcher()` in `js/main-vanilla.js`. - **Cmd+K command palette.** `Cmd/Ctrl+K` opens a fuzzy-searchable palette with 31+ commands (navigation, theme switching, toast demos). Keyboard-only navigation, Esc to close. Implemented in `initCommandPalette()`. - **Toast notification system.** Public API: `window.toast.show({title, message, type, duration})` plus `success`/`info`/`warning`/`error` shortcuts. Auto-dismiss, click-to-dismiss, stack of up to 5. - **Loading skeletons.** Real skeleton-loading state on all four dashboards (`index`, `index2`, `index3`, `index4`). Click "Refresh" in the page header to see KPI cards and the primary chart swap to shimmer placeholders for ~1.2s, then restore. New `.skeleton-line`, `.skeleton-block`, `.skeleton-circle`, and `.btn-spinner` CSS primitives. - **Sidebar tooltips on collapsed state.** Hovering an icon in the collapsed desktop sidebar shows the link label as a tooltip rendered outside the overflow-hidden parent (uses `getBoundingClientRect`). - **Self-updating calendar events.** `calendar.html` now generates events relative to the current date (today, +1d, +3d, recurring weekly/monthly patterns) so the demo never looks stale. - **Interactive inbox.** `inbox.html` rebuilt with a split-pane reader: 12 full HTML email bodies, click to open, star/archive/delete/reply actions, mobile-responsive sliding pane. - **New pages (11).** `profile.html`, `kanban.html` (HTML5 drag-and-drop), `pricing.html`, `invoice.html` (print-ready), `data-table.html` (working sort/filter/pagination), `wizard.html` (multi-step form), `docs.html` (TOC scrollspy via `IntersectionObserver`), `notifications.html`, `404.html`, `500.html`, `maintenance.html`. - **Component-showcase pages rewritten.** `button.html`, `badge.html`, `alert.html`, `modal.html`, `tab.html`, `switch.html`, `progress-bar.html`, `typo.html` — modern interactive demos including async loading-button pattern, 6 modal variants, three tab styles, SVG circular progress rings, brand-color form switches. - **Mobile header rebuild.** CSS Grid 3-column layout (`auto 1fr auto`) replacing the fragile flex stack. Notification dropdowns become `position: fixed` sheets below the header on mobile so they don't punch off-screen on narrow viewports. ### Changed - **Distinct dashboard variants.** `index2` is now a Sales pipeline dashboard, `index3` a Marketing analytics dashboard, `index4` a Projects dashboard. Each has its own KPI strip, primary chart, and supporting widgets — no longer a duplicate of `index`. - **`withCanvas()` re-init support.** Chart registrations are stored in a private registry; `window.__coolReinit()` walks the registry, destroys any existing Chart.js instances, and re-renders against the current DOM. Used by the dashboard refresh button. - **Hamburger uses Font Awesome.** Replaced the CSS-drawn `` with `` across 21 pages — fewer styles, more reliable rendering. - **Bell/message dropdowns.** Reskinned with `.notice-card` pattern (icon + title + meta + accent rail). Mobile collapses them into full-width sheets to avoid clipping. ### Fixed - **MDI font reference for caret.** `.account-item > .content > a:after` was still pointing at the removed Material-Design-Iconic-Font. Switched to the FA7 chevron-down (`\f078`). - **`fa-arrow-down-to-bracket` (Pro-only).** Replaced with `fa-download` everywhere (verified in FA7 Free metadata). - **`zmdi-account-box`-style prefix collisions.** Initial migration regex was too greedy and produced corrupted icons like `fa-user-box`. Mapped corrupted names back to correct FA equivalents. - **CSS prefix sweep over-aggression.** Restored unprefixed `linear-gradient(...)` rules that were stripped along with their `-webkit-` counterparts (5 overview tiles). - **`action=""` on the topbar search.** Empty form action was submitting POST to `file://` URLs and triggering "Unsafe attempt to load URL" errors. Now `action="#" onsubmit="return false"`. - **Avatar oval on mobile.** Legacy `flex: 0 0 45px` on `.account-item` was overriding the round avatar. Locked with `width:32px !important; height:32px !important; aspect-ratio: 1/1`. - **Logo border-right.** Removed `border-right: 1px solid #e5e5e5` on `.menu-sidebar .logo` — was creating a visible vertical line that looked broken. --- ## [3.0.0] - 2026-05-06 ### Major release — audit pass: dependency refresh, dead-code removal, accessibility, and SEO Comprehensive cleanup pass: latest dependencies, removed unused libraries, dropped duplicate icon font, accessibility fixes, per-page SEO meta, refactored JavaScript, and CSS prefix sweep. ### Added - **Per-page SEO metadata.** Unique `` and `<meta name="description">` for every page (24 pages). Open Graph and Twitter Card tags. `theme-color` meta. Auth pages (`login`, `register`, `forget-pass`) marked `noindex,nofollow`. - **Accessibility foundation.** Skip-to-main-content link (Bootstrap `visually-hidden-focusable`). `<main id="main-content">` element wrapping primary content on all 21 dashboard pages. `aria-label` + `role="button"` + `tabindex="0"` on the topbar's icon-only triggers (search, messages, emails, notifications, account menu, mobile hamburger). `for=`/`id=` label binding, `autocomplete`, and `required` on auth forms. `:focus-visible` outlines on interactive elements. - **Design tokens.** New `:root` block in `theme.css` with brand, surface, text, border, and shadow custom properties. Foundation for retheming and dark mode. - **Dark-mode hook.** Opt-in via `<html data-bs-theme="dark">`; tokens swap to dark surfaces. ### Changed - **Font Awesome 7.1.0 → 7.2.0** — current as of February 2026. - **Swiper.js 12.0.3 → 12.1.4** — patch updates. - **FullCalendar 6.1.11 → 6.1.20** — nine patch releases of fixes; switched to the modern `index.global.min.js` build naming. - **`main-vanilla.js` rewritten.** 1003 → 551 lines. Chart configs share a `sparklineOptions()` factory; per-canvas `withCanvas(id, fn)` guard; `var` → `const`/`let` throughout; UI behaviors split into named init functions (`initProgressBars`, `initTopbarDropdowns`, `initRightSidebar`, `initSubListArrows`, `initHamburgerMenu`, `initResponsiveTableShadows`). - **`bootstrap5-init.js` slimmed.** 69 → 12 lines. Only tooltips and popovers are explicitly instantiated — modals, dropdowns, tabs, collapses, alerts, and carousels self-instantiate via `data-bs-toggle` / `data-bs-ride`. - **`modern-plugins.js` cleaned.** 369 → 136 lines. Plugin styles moved out of injected `<style>` tags into `theme.css` (CSP-friendly, no FOUC). Lightbox now uses safe `createElement` / textContent rather than `innerHTML` interpolation. - **CSS vendor-prefix sweep.** 240 KB → 207 KB. 718 obsolete `-webkit-` / `-moz-` / `-ms-` / `-o-` declarations removed. Dropped legacy flex display values (`display: -webkit-box`, `display: -ms-flexbox`), legacy flex/box properties, prefixed `-webkit-calc()` values, prefixed linear-gradient declarations, `-webkit-sticky`, and three vendor `@-keyframes` blocks. Surviving prefixes are intentional (scrollbar styling, font-smoothing, placeholder pseudo-aliases). ### Removed - **AOS (Animate on Scroll) — last released 2018-10-03, unmaintained for 7 years.** No `data-aos` markup existed on any page. Removed `js/aos.js` (15 KB), `css/aos.css` (26 KB), and the corresponding `<script>`/`<link>` tags from all pages. - **Perfect Scrollbar.** Loaded on every page, never instantiated anywhere. Removed `vendor/perfect-scrollbar/` and the script/link tags from all 24 pages. Sidebars now use native browser scrolling. - **Swiper.js.** Loaded on every page, no `.swiper-*` markup anywhere. Removed `js/swiper-bundle-12.1.4.min.js`, `css/swiper-bundle-12.1.4.min.css`, and the script/link tags from all 24 pages. - **Material Design Iconic Font (`zmdi-*`).** Removed `vendor/mdi-font/`. Migrated 353 icon usages across 24 HTML files to Font Awesome 7 equivalents (`fa-solid` / `fa-regular`). Single icon font now renders the entire UI. - **35 `console.log` calls** stripped from shipped JS. The codebase now logs nothing in production. - **Generic placeholder meta** (`description="au theme template"`, `keywords="au theme template"`, `author="Hau Nguyen"`) replaced with real per-page metadata. The deprecated `meta name="keywords"` is no longer emitted. ### Fixed - Mixed `fas fa-*` / `fa fa-*` shorthand on 391 icon usages normalized to FA7's explicit `fa-solid fa-*` syntax. - `bootstrap5-init.js` no longer eagerly instantiates `bootstrap.Modal` / `Dropdown` / `Tab` / etc. for every matching selector on every page — saves memory, especially on form-heavy pages with many hidden modals. - Chart configs no longer wrapped in blanket `try/catch` blocks that swallowed every error silently. - Lightbox `innerHTML` injection replaced with safe DOM construction (`createElement` + `textContent`/`src`); closes the historical XSS surface on user-supplied image URLs. ### Performance impact (per page, gzipped where applicable) | Metric | Before | After | Δ | | --- | --- | --- | --- | | Bundled JS sent over the wire | ~330 KB | ~70 KB | **-260 KB** | | `theme.css` | 240 KB | 207 KB | **-33 KB** | | Total `js/` directory | 213 KB | 36 KB | **-177 KB** | | `console.log` calls in shipped JS | 35 | 0 | **-35** | | Vendor folders | 9 | 5 | -4 (FA, Bootstrap, Chart.js, FullCalendar, css-hamburgers) | ### Dependency Versions | Dependency | Previous | Current | Status | |------------|----------|---------|--------| | Bootstrap | 5.3.8 | **5.3.8** | Current | | Font Awesome | 7.1.0 | **7.2.0** | Updated | | Chart.js | 4.5.1 | **4.5.1** | Current | | FullCalendar | 6.1.11 | **6.1.20** | Updated | | Leaflet (map.html) | 1.9.4 | **1.9.4** | Current | | Perfect Scrollbar | 1.5.6 | _removed_ | Unused | | Swiper.js | 12.0.3 | _removed_ | Unused | | AOS | 2.3.4 | _removed_ | Unmaintained since 2018 | | MDI iconic font | bundled | _removed_ | Consolidated to Font Awesome 7 | --- ## [2.2.0] - 2025-12-01 ### Minor Release - December 2025 Dependency Updates This release brings all dependencies to their latest December 2025 versions, including a major Swiper.js upgrade to v12 with CSS-only theming. ### Added #### **Dependency Upgrades** - **Font Awesome 7.1.0** - Latest FA7 release with 4,500+ new icons and improved architecture - **Chart.js 4.5.1** - Latest patch with performance improvements and bug fixes - **Swiper.js 12.0.3** - Major upgrade with CSS-only theming, lighter bundle, and no preprocessor dependencies ### Changed #### **Framework Updates** - **Font Awesome 7.0.1 to 7.1.0** - Latest FA7 patch with icon improvements - **Chart.js 4.5.0 to 4.5.1** - Latest stable with Chrome zoom fixes - **Swiper.js 11.2.10 to 12.0.3** - Major version upgrade with modern CSS architecture #### **Swiper.js v12 Migration** - Switched from LESS/SCSS to pure CSS custom properties for theming - Navigation icons reworked to eliminate font-icon issues and CSP false positives - Virtual Slides improvements for `slidesPerView: 'auto'` scenarios ### Technical Details #### **Dependency Versions** | Dependency | Previous | Current | Status | |------------|----------|---------|--------| | Bootstrap | 5.3.8 | **5.3.8** | Current | | Font Awesome | 7.0.1 | **7.1.0** | Updated | | Chart.js | 4.5.0 | **4.5.1** | Updated | | Swiper.js | 11.2.10 | **12.0.3** | Major Upgrade | | Perfect Scrollbar | 1.5.6 | **1.5.6** | Current | --- ## [2.1.0] - 2025-09-05 ### Minor Release - Latest Dependencies & Performance Boost This release brings all dependencies to their latest 2025 versions for optimal performance, security, and modern web compatibility.
