+### 2026-01-22 - Version 0.3.0 - Self-Licensing
+
+**Overview:**
+
+Implemented self-licensing functionality. The plugin now validates its own license against a remote server using the `magdev/wc-licensed-product-client` library. Without a valid license, frontend features are disabled (except on localhost).
+
+**Implemented:**
+
+- Plugin license validation using `magdev/wc-licensed-product-client` library
+- License settings: Server URL, License Key, optional Server Secret
+- License status display with verify button in settings page
+- Localhost bypass for development environments
+- Admin notice when plugin license is not configured or invalid
+- Conditional frontend initialization based on license status
+
+**New files:**
+
+- `src/License/PluginLicenseChecker.php` - Singleton class for license validation
+
+**Modified files:**
+
+- `composer.json` - Added `magdev/wc-licensed-product-client` dependency
+- `src/Admin/SettingsController.php` - Added license settings fields and status display
+- `src/Plugin.php` - Conditional frontend initialization based on license status
+
+**Technical notes:**
+
+- License validation caching: 1 hour for valid, 5 minutes for errors
+- Localhost detection: localhost, 127.0.0.1, ::1, .localhost, .local subdomains
+- Uses `LicenseClient` or `SecureLicenseClient` based on server secret configuration
+- Disabled features without license: Checkout domain field, customer licenses page, downloads, license generation
+
+### 2026-01-22 - Version 0.3.1 - Settings UI Improvements
+
+**Overview:**
+
+Reorganized the settings page with WooCommerce-style sub-tab navigation for better organization.
+
+**Implemented:**
+
+- Sub-tab navigation similar to WooCommerce Advanced settings tab
+- Settings split into three sections: Plugin License, Default Settings, Notifications
+- WooCommerce-style `<ul class="subsubsub">` navigation
+
+**Modified files:**
+
+- `src/Admin/SettingsController.php` - Major refactoring with sub-sections
+- `languages/*` - Updated translations for new strings
+
+**Technical notes:**
+
+- Added `getSections()` returning three sub-tabs
+- Added `outputSections()` for WooCommerce-style navigation rendering
+- Split `getSettingsFields()` into section-specific methods using PHP 8 match expression
+- Hooks: `woocommerce_sections_licensed_product` for sub-navigation
