## [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
