+## [1.1.8] - 2025-12-31
+
+### Fixed
+
+- **CRITICAL**: Admin rendering bug where both General and Composable Options tabs showed simultaneously on initial page load
+- **CRITICAL**: Frontend product selector not appearing on product pages - WooCommerce's default add-to-cart button now hidden for composable products
+- **CRITICAL**: Price formatting not localized - prices now display with proper currency symbols, decimal separators, and thousand separators for all locales
+
+### Added
+
+- `wc_price()` Twig function for proper price formatting in templates
+- `formatPrice()` JavaScript method with full WooCommerce locale support
+- Price format localization data passed to frontend JavaScript (decimal/thousand separators, currency position, number of decimals)
+- `hide_default_add_to_cart()` method to prevent WooCommerce's default purchase UI for composable products
+
+### Changed
+
+- Enhanced CSS specificity with `!important` flags for proper tab visibility control
+- Template now uses `{{ fixed_price_html|raw }}` instead of raw currency concatenation
+- Product selector passes pre-formatted price HTML from `wc_price()` function
+- Frontend JavaScript updates prices dynamically using WooCommerce format settings
+
+### Technical
+
+- Modified files: assets/css/admin.css (+24 lines), includes/Cart_Handler.php (+14 lines), includes/Plugin.php (+7 lines), includes/Product_Selector.php (+2 lines), templates/product-selector.twig, assets/js/frontend.js (+28 lines)
+- All PHP files pass syntax validation
+- Supports Swiss format (CHF 50.-), European format (50,00 €), US format ($50.00), and all other WooCommerce locales
+- Thousand separator support: comma (1,000), dot (1.000), apostrophe (1'000), space (1 000)
+
+### Notes
+
+- This release fixes all three critical UI bugs reported in CLAUDE.md
+- Admin tabs now display correctly on initial page load without JavaScript flicker
+- Frontend product selector is now the only purchase interface (no WooCommerce default button)
+- All prices maintain proper locale formatting during dynamic updates
+
+## [1.1.7] - 2025-12-31
+
+### Added
+
+- Compiled .mo translation files for all 6 supported locales (de_DE, de_DE_informal, de_CH, de_CH_informal, fr_CH, it_CH)
+- WordPress can now load translations in admin and frontend areas
+
+### Fixed
+
+- **CRITICAL**: Missing translations in WordPress admin when using non-English locales
+- Settings page ("Composable Products", "Default Selection Limit", etc.) now properly translated
+- Product settings ("Composable Options", "Selection Criteria", etc.) now properly translated
+
+### Technical
+
+- Compiled .mo files from .po sources using msgfmt
+- All 6 locales now have complete translation coverage (56/56 strings translated and compiled)
+- .mo files required for WordPress i18n system to display translations
+
+### Notes
+
+- Previous versions included .po translation files but WordPress requires compiled .mo files
+- This release makes all existing translations actually visible to users
+
+## [1.1.6] - 2025-12-31
+
+### Added
+
+- Complete translations for all admin area strings across all 6 supported locales
+- "Fixed Price" field label and description translations
+
+### Changed
+
+- Updated translation template (.pot) to version 1.1.6
+- Simplified "How to calculate the price" description text
+
+### Technical
+
+- All .po files now include translations for v1.1.4 admin strings
+- 100% translation coverage maintained across all locales (56/56 strings)
+- German formal/informal variants properly differentiated (Sie vs. du)
+
+## [1.1.5] - 2025-12-31
+
+### Fixed
+
+- **CRITICAL**: Fixed Twig template error "Unknown 'esc_attr' filter" when rendering product selector
+- Template compatibility issue when other plugins (e.g., WooCommerce Tier and Package Prices) use Twig
+- WordPress escaping functions now properly registered as both Twig functions AND filters
+
+### Technical
+
+- Added `TwigFilter` registrations for `esc_html`, `esc_attr`, and `esc_url` in `Plugin::init_twig()`
+- Template can now use both syntax styles: `{{ value|esc_attr }}` (filter) and `{{ esc_attr(value) }}` (function)
+- Prevents conflicts when multiple plugins bundle their own Twig installations
+
+### Notes
+
+- Previous versions only registered escaping functions as Twig functions, not filters
+- Template used filter syntax (`|esc_attr`) which failed when parsed by external Twig instances
+- Fix ensures compatibility regardless of which Twig instance processes the template
+
+## [1.1.4] - 2025-12-31
+
+### Added
+
+- Fixed price field in Composable Options tab for easier price configuration
+- JavaScript toggle to show/hide fixed price field based on selected pricing mode
+
+### Changed
+
+- Simplified pricing mode description text in admin interface
+- Fixed price field now appears dynamically when "Fixed" pricing mode is selected
+
+### Technical
+
+- Added `_regular_price` field with `composable_fixed_price_field` CSS class in `Product_Data.php`
+- Implemented `toggleFixedPriceField()` JavaScript function in `assets/js/admin.js`
+- Progressive disclosure pattern improves admin UX by showing relevant fields only
+
+## [1.1.3] - 2024-12-31
+
+### Added
+
+- WooCommerce HPOS (High-Performance Order Storage) compatibility declaration
+- Prevents duplicate price calculations to avoid conflicts with other pricing plugins
+
+### Fixed
+
+- WooCommerce compatibility warnings with Analytics and other WooCommerce extensions
+- Price calculation conflicts with third-party pricing plugins
+
+### Technical
+
+- Added `before_woocommerce_init` hook to declare HPOS compatibility
+- Implemented static flag in `Cart_Handler::calculate_cart_item_price()` to prevent multiple executions
+- Added `composable_price_calculated` flag to cart items to prevent re-calculation by other plugins
+- Ensures composable products work with WooCommerce's modern order storage system
+
+## [1.1.2] - 2024-12-31
+
+### Fixed
+
+- **CRITICAL**: Fixed persistent "Class WC_Settings_Page not found" error that continued in v1.1.1
+- Root cause: Settings.php was being included too early (during plugin init) before WC_Settings_Page was loaded
+- Solution: Delayed Settings.php inclusion until `woocommerce_get_settings_pages` filter when class is guaranteed to exist
+
+### Technical
+
+- Removed `require_once Settings.php` from `Plugin::includes()` (line 93)
+- Added `require_once Settings.php` to `Plugin::add_settings_page()` (line 196)
+- Settings file now loads on-demand when WooCommerce requests settings pages
+- Previous hook change (woocommerce_init) was insufficient - class loading order was the real issue
+
+### Notes
+
+- v1.1.1 attempted to fix this with hook change but the error persisted
+- This version addresses the actual root cause: premature class extension
+
+## [1.1.1] - 2024-12-31
+
+### Fixed
+
+- Settings page initialization timing issue causing "Class WC_Settings_Page not found" error
+- Changed hook from `woocommerce_loaded` to `woocommerce_init` to ensure WC_Settings_Page class is available
+- Plugin now initializes after all WooCommerce core classes are loaded
+
+### Technical
+
+- Hook changed from `woocommerce_loaded` to `woocommerce_init` in wc-composable-product.php:65
+- `woocommerce_init` fires after WooCommerce has finished loading all its core classes including settings
+
+## [1.1.0] - 2024-12-31
+
+### Added
+
+- **Stock Management Integration**: Complete inventory tracking system for composable products
+  - Stock validation during product selection and add-to-cart
+  - Automatic stock deduction when orders are completed/processed
+  - Automatic stock restoration on order cancellation/refund
+  - Stock status indicators in product selector (In stock, Low stock, Out of stock)
+  - Visual feedback for out-of-stock items (disabled checkboxes, reduced opacity)
+  - Low stock warnings when 5 or fewer items remain
+  - Prevention of out-of-stock item selection
+  - Order notes documenting stock changes
+
+### Technical
+
+- New `Stock_Manager` class handling all stock operations
+- Integration with WooCommerce order status hooks
+- Stock information passed to frontend via Twig template
+- Enhanced CSS styling for stock status badges
+- Stock data stored in order item meta for accurate tracking
+- Backorder support detection and handling
+
+### Translation
+
+- Added 8 new translatable strings for stock messages
+- Updated Italian (Switzerland) translation with stock-related terms
+- Updated translation template (.pot file)
+
+## [1.0.1] - 2024-12-31
+
+### Fixed
+
+- Fatal error "Class WC_Settings_Page not found" during plugin activation
+- Changed initialization hook from `plugins_loaded` to `woocommerce_loaded` to ensure WooCommerce classes are available before plugin initialization
+- Settings page now correctly integrates as a tab in WooCommerce > Settings
+
+### Technical
+
+- Plugin now waits for `woocommerce_loaded` action before initializing
+- Prevents race condition where WooCommerce classes weren't loaded yet
+- Settings tab appears correctly in WooCommerce settings interface
+
