### For All Users

- **Enhanced Webhooks**: Track message edits more easily with the original message ID
- **Improved Stability**: Multiple bug fixes for more reliable operation

## Important Notes

✅ **Reverse Proxy Configuration**
- Set `APP_TRUSTED_PROXIES` to enable proxy header support
- For development: `APP_TRUSTED_PROXIES=0.0.0.0/0` (trust all)
- For production: Specify your proxy IP ranges like `APP_TRUSTED_PROXIES=10.0.0.0/8,172.16.0.0/12`
- Can also use CLI flag: `./whatsapp rest --trusted-proxies="0.0.0.0/0"`

✅ **Media Download Configuration**
- Default behavior unchanged: media is auto-downloaded
- To disable: Set `WHATSAPP_AUTO_DOWNLOAD_MEDIA=false` or use `--auto-download-media=false`
- Affects: audio, documents, images, stickers, videos from incoming messages

✅ **Breaking Changes**
- None - all changes are backward compatible
- Existing deployments will continue to work without configuration changes

🔧 **Recommended Actions**
- If deploying behind a reverse proxy, configure `APP_TRUSTED_PROXIES` for correct URL generation
- Update your `.env` file based on the updated `.env.example`
- If experiencing high storage usage, consider disabling auto-download media

## Configuration Examples

```bash
APP_TRUSTED_PROXIES=0.0.0.0/0
WHATSAPP_AUTO_DOWNLOAD_MEDIA=true
```

**Using CLI Flags:**

```

**Docker Compose:**

  - WHATSAPP_AUTO_DOWNLOAD_MEDIA=true
```

## Summary
