-### 2026-01-23 - Version 0.3.5 - Download List UI Improvement
+### 2026-01-23 - Version 0.3.5 - Dashboard Widget & Auto-Expire
 
 **Overview:**
 
-Improved the download list layout in customer account licenses page with a two-row format.
+Added admin dashboard widget for license statistics and automatic license expiration via daily cron job.
 
 **Implemented:**
 
-- Downloads now displayed in two rows per entry
+- Admin dashboard widget showing license statistics (total, active, expiring soon, expired)
-- First row: File download link
+- Status breakdown display with color-coded badges
-- Second row: Metadata (version, date, checksum)
+- License type breakdown (time-limited vs lifetime)
-- Better visual separation and readability
+- Daily wp-cron job to auto-expire licenses past their expiration date
+- License expired email notification sent when license auto-expires
+- Downloads in customer account now displayed in two-row format
+
+**New files:**
+
+- `src/Admin/DashboardWidgetController.php` - WordPress dashboard widget controller
+- `src/Email/LicenseExpiredEmail.php` - WooCommerce email for expired license notifications
 
 **Modified files:**
 
+- `src/Plugin.php` - Added DashboardWidgetController instantiation
+- `src/License/LicenseManager.php` - Added `getExpiredActiveLicenses()` and `autoExpireLicense()` methods
+- `src/Email/LicenseEmailController.php` - Added auto-expire logic and LicenseExpiredEmail registration
 - `templates/frontend/licenses.html.twig` - Restructured download list with two-row layout
-- `assets/css/frontend.css` - Added `.download-item`, `.download-row-file`, `.download-row-meta` styles
+- `assets/css/frontend.css` - Added dashboard widget and download list styles
 
 **Technical notes:**
 
-- Changed `<li>` from single-row flex to column flex layout
+- Dashboard widget uses `wp_add_dashboard_widget()` hook, requires `manage_woocommerce` capability
-- Metadata row indented with left padding for visual hierarchy
+- Widget displays statistics from existing `LicenseManager::getStatistics()` method
-- Updated responsive CSS for mobile devices
+- Auto-expire runs during daily `wclp_check_expiring_licenses` cron event
+- `getExpiredActiveLicenses()` finds licenses with past expiration date but still active status
+- `autoExpireLicense()` updates status to expired and returns true if changed
+- LicenseExpiredEmail follows same pattern as LicenseExpirationEmail (warning vs expired)
+- Expired notification tracked via user meta to prevent duplicate emails
