 ## [Unreleased]

+## [0.5.12] - 2026-01-27
+
+### Fixed
+
+- **CRITICAL:** Fixed stock indicator ("1 in stock") appearing in cart for licensed variable product variations
+- Override `get_children()` with direct SQL query to bypass WooCommerce's `is_type('variable')` check
+- Override `get_variation_attributes()` to properly load taxonomy attribute terms
+- Override `get_variation_prices()` to prevent fatal error with null `$this->prices_array`
+- Override `get_available_variations()` with empty `availability_html` for variations
+- Added `is_type()` override to return true for both 'licensed-variable' and 'variable' type checks
+- Added multiple stock-related filters: `woocommerce_get_availability_text`, `woocommerce_product_get_stock_quantity`, `woocommerce_product_variation_get_stock_quantity`
+- Improved `isLicensedProductOrVariation()` check using `WC_Product_Factory::get_product_type()` for reliable parent type detection
+
+### Changed
+
+- `LicensedProductVariation` now includes `get_availability()`, `managing_stock()`, and `is_purchasable()` overrides
+- Simplified `isVirtual()` to use shared `isLicensedProductOrVariation()` helper
+
+## [0.5.11] - 2026-01-27
+
+### Fixed
+
+- **CRITICAL:** Fixed "sold out" message on licensed variable products by correcting `is_purchasable()` method
+- Variable products don't have a direct price - `is_purchasable()` now delegates to parent `WC_Product_Variable` class
+- Fixed variation class detection by using product ID parameter instead of unreliable global `$post`
+- Product class filter now properly accepts all 4 WooCommerce filter parameters for reliable variation detection
+
+## [0.5.10] - 2026-01-27
+
+### Fixed
+
+- Fixed licensed variable products not showing variations even when attributes are defined
+- Re-load product via `wc_get_product()` to ensure correct class instance is used
+- Removed overly strict type check that was preventing variations from displaying
+- Now mirrors WooCommerce's standard `woocommerce_variable_add_to_cart()` implementation
+
+## [0.5.9] - 2026-01-27
+
+### Fixed
+
+- Fixed frontend error on licensed variable products when no attributes are defined
+- Added null checks for `get_variation_attributes()`, `get_available_variations()`, and `get_default_attributes()`
+- Show informative message instead of error when product has no variations configured
+- Changed product type check from `instanceof` to `is_type()` for better compatibility
+
+## [0.5.8] - 2026-01-27
+
+### Fixed
+
+- **CRITICAL:** Fixed critical error on frontend product pages for licensed variable products
+- Variable product add-to-cart template now passes required variables (`available_variations`, `attributes`, `selected_attributes`)
+- Variants tab no longer disappears when saving attributes on licensed variable products
+- Added WooCommerce AJAX event listeners to maintain tab visibility during attribute operations
+
+### Changed
+
+- Improved JavaScript event handling for licensed-variable product type in admin
+- Added listeners for `woocommerce_variations_loaded`, `woocommerce_variations_added`, `woocommerce_variations_saved` events
+- Added AJAX complete handler for attribute save operations
+

+
+### 2026-01-27 - Version 0.5.6 - License Settings Tab Visibility Fix
+
+**Overview:**
+
+Fixed License Settings tab visibility for non-licensed product types and updated README with v0.5.x features.
+
+**Bug Fix:**
+
+- License Settings tab now only shows for Licensed Product and Licensed Variable Product types
+- Previously the tab was visible on all product types due to CSS `!important` override forcing `display: block`
+
+**Modified files:**
+
+- `assets/css/admin.css` - Changed from `display: block !important` to `display: none` for `.show_if_licensed` and `.show_if_licensed-variable`
+- `src/Product/LicensedProductType.php` - Added consolidated `toggleLicensedProductOptions()` JavaScript function
+- `README.md` - Updated with complete feature documentation for v0.5.x features
+
+**Technical notes:**
+
+- CSS now hides License Settings tab by default
+- JavaScript `toggleLicensedProductOptions()` function shows/hides tab based on product type selector
+- Function is called both on page load and on product type change
+- README updated with: Variable Licensed Products, Multi-Domain Licensing, Per-License Secrets, Download Statistics, Configurable Rate Limiting
+
+**Release v0.5.6:**
+
+- Created release package: `releases/wc-licensed-product-0.5.6.zip` (1.1 MB)
+- SHA256: `4d35a319fe4cb4e7055bae17fc030487ca05e5e9ac905f76d0ac62002bde4336`
+- Tagged as `v0.5.6` and pushed to `main` branch
+
+### 2026-01-27 - Version 0.5.7 - Settings UI Cleanup
+
+**Overview:**
+
+Removed redundant "Default" prefix from setting labels on the Default Settings page for cleaner UI.
+
+**Changed:**
+
+- "Max Activations" (was "Default Max Activations")
+- "License Validity (Days)" (was "Default License Validity (Days)")
+- "Bind to Major Version" (was "Default Bind to Major Version")
+
+**Modified files:**
+
+- `src/Admin/SettingsController.php` - Removed "Default" prefix from three setting labels
+
+**Technical notes:**
+
+- Labels are cleaner since the page section itself is already named "Default Settings"
+- No functional changes, purely UI improvement
+- Updated all translations (388 strings)
+
+**Release v0.5.7:**
+
+- Created release package: `releases/wc-licensed-product-0.5.7.zip` (856 KB)
+- SHA256: `ceb4d57598f576f4f172153ff80df8c180ecd4dca873cf109327fc5ac718930f`

+### 2026-01-27 - Version 0.5.8-0.5.11 - Licensed Variable Product Fixes
+
+**Overview:**
+
+Series of bug fixes for licensed variable products that were showing frontend errors and not displaying properly.
+
+**v0.5.8 - Initial Fix:**
+
+- Fixed critical error on frontend product pages for licensed variable products
+- Variable product add-to-cart template now passes required variables (`available_variations`, `attributes`, `selected_attributes`)
+- Added JavaScript event listeners for WooCommerce AJAX events to maintain admin variants tab visibility
+
+**v0.5.9 - Null Checks:**
+
+- Added null checks for `get_variation_attributes()`, `get_available_variations()`, and `get_default_attributes()`
+- Show informative message instead of error when product has no variations configured
+- Changed product type check from `instanceof` to `is_type()` for better compatibility
+
+**v0.5.10 - Product Loading:**
+
+- Re-load product via `wc_get_product()` to ensure correct class instance is used
+- Removed overly strict type check that was preventing variations from displaying
+
+**v0.5.11 - Final Fix:**
+
+- **CRITICAL:** Fixed "sold out" message on licensed variable products
+- `LicensedVariableProduct::is_purchasable()` now delegates to parent `WC_Product_Variable` class (variable products don't have direct prices - only variations do)
+- Fixed `getProductClass()` filter to accept all 4 WooCommerce parameters and use product_id for reliable variation parent detection
+- Added fallback to global `$post` when product_id not available
+
+**Modified files:**
+
+- `src/Product/LicensedProductType.php` - Fixed `variableAddToCartTemplate()` and `getProductClass()` methods
+- `src/Product/LicensedVariableProduct.php` - Fixed `is_purchasable()` method
+- `wc-licensed-product.php` - Version bumps
+
+**Technical notes:**
+
+- WooCommerce `woocommerce_product_class` filter has 4 parameters: `$className`, `$productType`, `$postType`, `$productId`
+- Variable products delegate purchasability to their variations - checking `get_price()` on parent is incorrect
+- Variation parent detection must use product ID, not global `$post` which may not be set on frontend
+
+**Release v0.5.11:**
+
+- Created release package: `releases/wc-licensed-product-0.5.11.zip` (857 KB)
+- SHA256: `32571178bfa8f0d0a03ed05b498d5f9b3c860104393a96732e86a03b6de298d2`
