# Changelog

All notable changes to this project will be documented in this file.

## [1.0.9] - 2026-02-19

### Performance

- **Color variation CSS transient caching** (`functions.php`): `wp_bootstrap_variation_colors()` now caches the generated inline CSS in a 24-hour WordPress transient keyed by `wp_bootstrap_variation_css_` + an MD5 of the active stylesheet slug. Previously the palette iteration and CSS string building ran on every frontend page load. The transient is immediately invalidated on `switch_theme` and `save_post_wp_global_styles`, so changes made via the Design Editor are reflected instantly.
- **Twig template recompilation gated behind `WP_DEBUG`** (`inc/Twig/TwigService.php`): `auto_reload` in the Twig `Environment` constructor was hardcoded to `true`, causing Twig to stat every compiled template file on every request to check for source changes. Changed to `WP_DEBUG` so template recompilation only occurs during development. In production (`WP_DEBUG = false`) compiled Twig templates are served from cache without filesystem mtime checks.

## [1.0.8] - 2026-02-19

### Security

- **Archive XSS hardening**: `ContextBuilder::getArchiveData()` now wraps `get_the_archive_title()` and `get_the_archive_description()` with `wp_kses_post()`. Term descriptions are user-editable by Editors and above; without sanitization an injected `<script>` tag would execute via the `|raw` filter in `archive.html.twig`
- **Comment author XSS hardening**: `ContextBuilder::buildCommentTree()` now applies `esc_html()` to `comment_author` and `esc_url()` to `comment_author_url` at the data source, preventing injection via user-supplied comment fields
- **Dark mode localStorage whitelist**: `getPreferredTheme()` in `dark-mode.js` now validates the stored theme value against `['dark', 'light']` before use, preventing attribute injection from a tampered localStorage value written by a third-party script
- **Twig escaping functions marked safe**: `esc_html()`, `esc_attr()`, and `esc_url()` registered in `TwigService` are now declared with `['is_safe' => ['html']]`, preventing double-encoding if Twig autoescape is ever enabled

### Changed

- `views/partials/comment-item.html.twig`: Comment author URL now output via `{{ comment.author_url|raw }}` (escaped in PHP) instead of calling `esc_url()` from the template, keeping escaping logic in one place

## [1.0.7] - 2026-02-18

### Added

- `do_shortcode()` registered as a Twig function in `TwigService`, allowing shortcodes to be rendered directly from Twig templates via `{{ do_shortcode('[shortcode]') }}`

## [1.0.6] - 2026-02-14

### Fixed

- Sidebar widgets not rendered on pages using the "Page with Sidebar" template — `ContextBuilder::build()` only populated `sidebar` context for `is_home()`, so `page-sidebar.html.twig` received no widget data

## [1.0.5] - 2026-02-11

### Added

- 11 new translation files: de_CH_informal, de_DE, de_DE_informal, en_GB, es_ES, fr_CH, it_CH, it_IT, nl_NL, pl_PL, pt_PT (total: 13 locales + en_US base)
- Compiled .mo files for all 13 translations

### Changed

- Standardized all .po file names to use `wp-bootstrap-` prefix (WordPress convention: `{text-domain}-{locale}.po`)

## [1.0.4] - 2026-02-11

### Added

- `wp_bootstrap_should_render_template` filter in `TemplateController::render()` — allows plugins and child themes to prevent the theme from rendering a specific request, enabling clean separation of concerns when plugins handle their own page rendering

## [1.0.3] - 2026-02-11

### Fixed

- Double `<h1>` headings on pages where plugins provide their own titles — `page.html.twig` now wraps `<h1>` in `{% if post.title is not empty %}` guard so plugins can suppress it by passing empty `post.title`

## [1.0.2] - 2026-02-10

### Fixed

- Missing HTML `<title>` tag on all pages — theme never declared `add_theme_support('title-tag')`, so WordPress's `_wp_render_title_tag()` hook was inactive during `wp_head()` output in Twig templates

## [1.0.1] - 2026-02-09

### Added

- Bootstrap Icons web font integration — all 2,000+ icons available via `<i class="bi bi-*"></i>` CSS classes
- `copy:icons` build step to copy icon font files (`.woff`, `.woff2`) from `node_modules` to `assets/fonts/`
- Bootstrap Icons SCSS imported in both frontend and editor stylesheets for icon support in templates and block editor

## [1.0.0] - 2026-02-08

### Added

- Sidebar widget area (`primary-sidebar`) registered via `register_sidebar()` — manageable in Appearance > Widgets
- Widget area rendering in Twig sidebar with fallback to built-in content (recent posts, search, tags) when no widgets assigned
- Widget area description strings added to all translation files (en_US, de_CH, fr_FR)

### Changed

- Updated README.md with accurate feature counts (15 style variations, 41 patterns, 3 translations)
- Added documentation for style variation bridge, widget areas, RTL support, and accessibility features

## [0.3.3] - 2026-02-08

### Fixed

- Style variation colors not applied to Bootstrap frontend — bridge function checked wrong palette origin (`custom` instead of `theme`)
- Variation detection now compares `theme` origin against base theme.json defaults instead of looking for slugs in `custom` origin

## [0.3.2] - 2026-02-08

### Fixed

- Dark mode body colors overridden by WordPress global styles (`styles.color` in `theme.json` generated conflicting `body` CSS)
- Dark mode styling for plugin-generated form elements (`select`, `input`, `textarea`) that lack Bootstrap classes
- Footer columns template used hardcoded `bg-dark text-light` instead of semantic `bg-body-tertiary`
- Style variation bridge function ran with default palette when no variation was active, causing unnecessary CSS overrides

### Changed

- Removed `styles.color` from `theme.json` to prevent WordPress from generating body background/text CSS that conflicts with Bootstrap dark mode
- Added `!important` override in `_custom.scss` for `html[data-bs-theme="dark"] body` to ensure Bootstrap dark mode takes precedence
- Added broad dark mode rules for native form elements in `_custom.scss`

## [0.3.1] - 2026-02-08

### Added

- 4 new light style variations: Rose, Sand, Lavender, Mint

- RTL language support: conditional RTL stylesheet, logical CSS properties for blockquote and list styles
- French (fr_FR) translation with all ~216 strings translated
- CSS classes for post thumbnails, card thumbnails, sidebar headings, and hero overlays (replacing inline styles)

### Fixed

- XSS vulnerability in search results template (`search_query` now escaped with `|e('html')`)
- Comment author URLs now explicitly escaped with `esc_url()` in Twig templates

### Changed

- Block style `blockquote-accent` uses `border-inline-start` instead of `border-left` for RTL compatibility
- Block style `list-unstyled` uses `padding-inline-start` instead of `padding-left` for RTL compatibility
- Inline styles in Twig templates replaced with CSS classes for maintainability
- Updated translation files (`.pot` and `de_CH.po`) with new accessibility strings
- Build pipeline includes RTL SCSS compilation step
