+### 2026-01-22 - Version 0.2.1 - UI Improvements
+
+**Overview:**
+

+
+**Implemented:**
+
+- File upload field for SHA256 hash (.sha256 or .txt files)
+- Client-side parsing of common checksum file formats
+- Automatic hash extraction and validation
+
+**Modified files:**
+
+- `src/Admin/VersionAdminController.php` - Changed text input to file input for hash
+- `assets/js/versions.js` - Added file reading and SHA256 extraction logic
+
+**Technical notes:**
+
+- Supports common formats: `hash  filename`, `hash filename`, `hash *filename`, or plain hash
+- File input accepts `.sha256` and `.txt` extensions
+- Hash validated to be exactly 64 hex characters before submission

+### 2026-01-22 - Version 0.2.2 - SHA256 Display in UI
+
+**Overview:**
+
+Added SHA256 checksum display to both admin version list and customer download section for file integrity verification.
+
+**Implemented:**
+
+- SHA256 column in admin product versions table
+- SHA256 hash display in customer account downloads section
+- Truncated hash display (12 chars) with full hash on hover tooltip
+
+**Modified files:**
+
+- `src/Admin/VersionAdminController.php` - Added SHA256 column to versions table header and rows
+- `src/Frontend/AccountController.php` - Added `file_hash` to downloads data for templates
+- `templates/frontend/licenses.html.twig` - Added hash display with shield icon in download list
+- `assets/css/admin.css` - Added `.file-hash` styles for admin table
+- `assets/css/frontend.css` - Added `.download-hash` styles for customer downloads
+- `languages/*` - Updated all translation files (304 strings)
+
+**Technical notes:**
+
+- Admin table shows hash in monospace `<code>` element with `cursor: help`
+- Frontend shows green shield dashicon next to truncated hash
+- Both use HTML `title` attribute for full hash on hover
+- Gracefully handles missing hash (shows em-dash in admin, hides section in frontend)
