+### 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.

+- Automatic hash extraction and validation
+
+**Modified files:**
+
+- `src/Admin/VersionAdminController.php` - Changed text input to file input for hash

+
+**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

+
+**Implemented:**
+
+- SHA256 column in admin product versions table

+
+**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)

-### 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))
