# Changelog All notable changes to this project 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). ## [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 ## [1.0.0] - 2024-12-31 ### Added - Initial release - Composable product type for WooCommerce - Product selection by category, tag, or SKU -
