 ## [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
