+### 2026-01-24 - Version 0.3.7 - Dashboard Improvements & Download Counter
+
+**Overview:**
+
+Fixed dashboard widget bugs, improved UI consistency, and added download tracking functionality with a new statistics widget.
+
+**Bug Fixes:**
+
+- Fixed: Dashboard widget "View All Licenses" link used wrong page slug (`wc-licensed-product-licenses` instead of `wc-licenses`)
+- Fixed: Download links in customer account resulted in 404 errors due to missing query var registration
+- Added `license-download` endpoint registration during plugin activation in `Installer::activate()`
+- Added `addDownloadQueryVar()` method to `DownloadController` for proper WordPress endpoint recognition
+
+**UI Improvements:**
+
+- Removed redundant "Status Breakdown" section from license statistics widget (info already shown in stat cards above)
+- Changed License Types section to use card-style layout matching the stats row above
+- Cleaned up unused CSS for status badges
+
+**New Features:**
+
+- Download counter for licensed product versions (tracked per version in database)
+- New Download Statistics admin dashboard widget showing:
+  - Total downloads count
+  - Top 5 products by downloads
+  - Top 5 versions by downloads
+
+**New files:**
+
+- `src/Admin/DownloadWidgetController.php` - Dashboard widget for download statistics
+
+**New methods in VersionManager:**
+
+- `incrementDownloadCount()` - Atomically increment download count for a version
+- `getTotalDownloadCount()` - Get total downloads across all versions
+- `getDownloadStatistics()` - Get download stats grouped by product and version
+
+**Modified files:**
+
+- `src/Installer.php` - Added `download_count` column to versions table, added `license-download` endpoint registration
+- `src/Product/ProductVersion.php` - Added `downloadCount` property and `getDownloadCount()` method
+- `src/Product/VersionManager.php` - Added download counting methods
+- `src/Frontend/DownloadController.php` - Added query var registration, increment download count on file serve
+- `src/Admin/DashboardWidgetController.php` - Fixed URL, removed Status Breakdown, changed License Types to cards
+- `src/Plugin.php` - Added DownloadWidgetController instantiation
+
+**Technical notes:**
+
+- Download count is incremented atomically using SQL `download_count = download_count + 1`
+- Statistics queries use SQL aggregation with product name enrichment via `wc_get_product()`
+- WordPress endpoints require both `add_rewrite_endpoint()` AND `query_vars` filter registration
+- Existing installations need to flush rewrite rules (Settings > Permalinks > Save) or reactivate plugin
+
+**Release v0.3.7:**
+
+- Created release package: `releases/wc-licensed-product-0.3.7.zip` (827 KB)
+- SHA256: `e93b2ab06f6d43c2179167090e07eda5db6809df6e391baece4ceba321cf33f6`
