+## [1.3.0] - 2026-01-25
+
+### Breaking Changes
+
+- **PHP 8.3 Required**: Minimum PHP version increased from 7.4 to 8.3 to support modern dependencies and the license client library. Users on older PHP versions will see an admin notice and the plugin will not load.
+
+### Added
+
+- **License Management**: Integrated `magdev/wc-licensed-product-client` library for license validation and activation
+  - New "License" settings tab for entering license server URL and license key
+  - License validation and activation via AJAX with visual feedback
+  - License status display showing active/inactive state, expiration date, and last check time
+  - Cached license status with daily auto-refresh
+
+- **Settings Page Sub-tabs**: Split the settings page into "General" and "License" tabs using modern WooCommerce patterns
+  - Refactored to use `get_own_sections()` and `get_settings_for_{section}_section()` methods
+  - Improved navigation and organization of settings
+
+- **PHP Version Check**: Added runtime PHP version validation with admin notice for incompatible servers
+
+### Changed
+
+- Updated composer.json to require PHP 8.3+ and added `magdev/wc-licensed-product-client` dependency
+- Settings class now uses modern WooCommerce settings API patterns
+
+### Technical Details
+
+**New Dependencies**:
+- `magdev/wc-licensed-product-client: ^0.1` (from private repository)
+- `symfony/http-client: ^7.0` (transitive)
+- `psr/log: ^3.0`, `psr/cache: ^3.0`, `psr/http-client: ^1.0` (transitive)
+
+**License Client Integration**:
+- Uses `LicenseClient` class for API communication
+- AJAX endpoints: `wc_tpp_validate_license`, `wc_tpp_activate_license`
+- License status cached in WordPress transient (`wc_tpp_license_status`)
