+### 2026-01-22 - Version 0.2.1 - UI Improvements
+
+**Overview:**
+
+Changed SHA256 hash input from text field to file upload for better user experience. The hash is now calculated automatically from a checksum file.
+
+**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)

+### 2026-01-22 - Version 0.3.0 - Self-Licensing

+
+**Technical notes:**

+- 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

-### Client Examples
+### Response Signing (Optional)
 
-Ready-to-use API client examples are available in `docs/client-examples/`:
+When the server is configured with a shared secret, all API responses include cryptographic signatures for tamper protection:
+
+**Configuration (wp-config.php):**
+
+```php
+define('WC_LICENSE_SERVER_SECRET', 'your-secure-random-string-min-32-chars');
+```
+
+**Response Headers:**
+
+| Header | Description |
+| ------ | ----------- |
+| `X-License-Signature` | HMAC-SHA256 signature of the response body |
+| `X-License-Timestamp` | Unix timestamp when the response was generated |
+
+The signature prevents man-in-the-middle attacks and ensures response integrity. Use the `magdev/wc-licensed-product-client` Composer package with the `SecureLicenseClient` class to automatically verify signatures.
+
+### Client Libraries & Examples
+
+**PHP (Recommended):** Install the official client library via Composer:
+
+```bash
+composer require magdev/wc-licensed-product-client
+```
+
+The library provides:
+
+- `LicenseClient` - Standard client for API calls
+- `SecureLicenseClient` - Client with automatic response signature verification
+
+**Example clients** for other languages are available in `docs/client-examples/`:
 
 - **cURL** - Shell script examples ([curl.sh](docs/client-examples/curl.sh))
-- **PHP** - Client class with examples ([php-client.php](docs/client-examples/php-client.php))
+- **PHP** - Standalone client example ([php-client.php](docs/client-examples/php-client.php))
 - **Python** - Client class with dataclasses ([python-client.py](docs/client-examples/python-client.py))
 - **JavaScript** - Browser and Node.js client ([javascript-client.js](docs/client-examples/javascript-client.js))
 - **C#** - Async client with System.Text.Json ([csharp-client.cs](docs/client-examples/csharp-client.cs))
