+### 2026-01-24 - Version 0.4.0 - Self-Licensing Prevention
+
+**Overview:**
+
+Added self-licensing prevention to avoid circular dependency when the plugin tries to validate its license against itself.
+
+**Implemented:**
+
+- Self-licensing detection: Plugin automatically bypasses license validation when the configured license server URL points to the same WordPress installation
+- New `isSelfLicensing()` method in `PluginLicenseChecker` to detect circular licensing scenarios
+- New `normalizeDomain()` helper method for domain comparison (strips www prefix, lowercases)
+- Cache property `$isSelfLicensingCached` for efficient repeated checks
+
+**Modified files:**
+
+- `src/License/PluginLicenseChecker.php` - Added self-licensing detection methods and bypass logic
+
+**Technical notes:**
+
+- Self-licensing detection compares normalized domains of license server URL and current site URL
+- Prevents circular dependency where plugin would try to validate against itself
+- Plugins can only be validated against the original store from which they were obtained
+- Bypass check added to both `isLicenseValid()` and `validateLicense()` methods
+- Cache clearing via `clearCache()` also clears the self-licensing check cache

+
+### 2026-01-25 - Version 0.5.0 - Multi-Domain Licensing
+
+**Overview:**
+
+Major feature release enabling customers to purchase multiple licenses for different domains in a single order. Each cart item quantity requires a unique domain at checkout.
+
+**Implemented:**
+
+- Multi-domain licensing support with new setting "Enable Multi-Domain Licensing"
+- Multi-domain checkout UI for both classic checkout and WooCommerce Blocks
+- Grouped license display in customer account page by product/order (package view)
+- "Older versions" collapsible section in customer download area
+- Updated email templates to show licenses grouped by product
+- DOM injection fallback for WooCommerce Blocks when React component fails
+
+**New Setting:**
+
+- `wclp_enable_multi_domain` - Enable/disable multi-domain licensing mode
+
+**New Order Meta:**
+
+- `_licensed_product_domains` - Array of domain data for multi-domain orders:
+
+  ```php
+  [
+      ['product_id' => 123, 'domains' => ['site1.com', 'site2.com']],
+      ['product_id' => 456, 'domains' => ['another.com']],
+  ]
+  ```
+
+**Modified files:**
+
+- `src/Admin/SettingsController.php` - Added multi-domain setting
+- `src/Checkout/CheckoutController.php` - Multi-domain field rendering and validation
+- `src/Checkout/CheckoutBlocksIntegration.php` - WooCommerce Blocks multi-domain support
+- `src/Checkout/StoreApiExtension.php` - Multi-domain data handling in Store API
+- `src/Frontend/AccountController.php` - Grouped license display by product
+- `src/Email/LicenseEmailController.php` - Grouped license email templates
+- `src/Plugin.php` - Multi-domain license generation
+- `src/License/LicenseManager.php` - Multi-domain license creation
+- `src/Admin/OrderLicenseController.php` - Multi-domain order display
+- `assets/js/checkout-blocks.js` - Complete rewrite for ExperimentalOrderMeta slot
+- `assets/js/frontend.js` - Older versions toggle functionality
+- `assets/css/frontend.css` - Package-based layout styles
+- `templates/frontend/licenses.html.twig` - Grouped license template
+
+**Technical notes:**
+
+- WooCommerce Blocks integration uses `ExperimentalOrderMeta` slot with `registerPlugin`
+- DOM injection fallback activates after 2 seconds if React component fails to render
+- Multi-domain validation ensures unique domains per product
+- Backward compatible: existing single-domain orders continue to work
+- New `getLicensesByOrderAndProduct()` method returns all licenses for a product in an order
+- Customer account groups licenses by product for package-style display
+- Email templates show licenses in table format grouped by product
+
+**Bug Fix:**
+
+- Fixed: Domain fields not rendering in WooCommerce Blocks checkout
+- Root cause: `registerCheckoutBlock` approach requires manual block editor configuration
+- Fix: Switched to `ExperimentalOrderMeta` slot pattern with `registerPlugin` + DOM injection fallback
+
+**Translation Updates:**
+
+- Added 19 new strings for multi-domain functionality
+- Fixed all fuzzy translations in German (de_CH)
+- Updated .pot template and compiled .mo files
+
+**Release v0.5.0:**
+
+- Created release package: `releases/wc-licensed-product-0.5.0.zip` (863 KB)
+- SHA256: `446804948e5f99d705b548061d5b78180856984c58458640a910ada8f27f5316`

+
+### 2026-01-26 - Version 0.5.1 - Admin UI Fixes
+
+**Overview:**
+
+Bug fix release improving admin UI usability for version management and license overview.
+
+**Bug Fixes:**
+
+- Fixed: Product versions in admin now sort by version DESC when adding via AJAX
+- Fixed: License actions in admin overview are now always visible (not just on hover)
+
+**Modified files:**
+
+- `assets/css/admin.css` - Added `!important` to `.licenses-table .row-actions` for permanent visibility
+- `assets/js/versions.js` - Added `compareVersions()` function and sorted insertion for AJAX-added versions
+
+**Technical notes:**
+
+- Version sorting uses semantic version comparison (major.minor.patch)
+- New versions are inserted in correct sorted position in the table instead of always appending
+- CSS override uses `!important` to overcome WordPress default hover-only behavior for row actions
+- `compareVersions()` function compares version strings numerically (1.10.0 > 1.9.0)
+
+**Release v0.5.1:**
+
+- Created release package: `releases/wc-licensed-product-0.5.1.zip` (863 KB)
+- SHA256: `a489f0b8cfcd7d5d9b2021b7ff581b9f1a56468dfde87bbb06bb4555d11f7556`

-4. Invalid signatures cause the client to reject the response

 ## Requirements

+### Per-License Secrets
+
+Each customer receives a unique secret derived from their license key. This means:
+
+- Customers only know their own secret, not the master server secret
+- If one customer's secret is leaked, other customers are not affected
+- The server uses HKDF-like derivation to create unique secrets
+
+#### How Customers Get Their Secret
+
+Customers can find their per-license verification secret in their account:
+
+1. Log in to the store
+2. Go to My Account > Licenses
+3. Click "API Verification Secret" under any license
+4. Copy the 64-character hex string
+
+This secret is automatically derived from the customer's license key and the server's master secret.
+
+#### Using the Customer Secret
+
+```php
+use Magdev\WcLicensedProductClient\SecureLicenseClient;
+use Symfony\Component\HttpClient\HttpClient;
+
+// Customer uses their per-license secret (from account page)
+$client = new SecureLicenseClient(
+    httpClient: HttpClient::create(),
+    baseUrl: 'https://shop.example.com',
+    serverSecret: 'customer-secret-from-account-page', // 64 hex chars
+);
+
+$info = $client->validate('XXXX-XXXX-XXXX-XXXX', 'example.com');
+```
+
 ### Secret Key Rotation
 
 To rotate the server secret:
 
 1. Deploy new secret to server
-2. Update client configurations
+2. All per-license secrets change automatically (they're derived)
-3. Old signatures become invalid immediately
+3. Customers must copy their new secret from their account page
+4. Old signatures become invalid immediately
 
 For zero-downtime rotation, implement versioned secrets:
