Vers van de pers:
**Beta 0.97b**
- **Bug Fix: on-device update**
- Implemented a new SSL certificate for the on-device update function.
- **Bug Fix: Integrated Icon Downloader**
- Resolved an issue causing the integrated icon downloader to malfunction in certain countries. To apply this fix, you may need to delete the `DoNotTouch.json` file and restart AWTRIX.
- **Expanded Polish Language Support**
- Added support for the Polish language by converting Polish characters to their ASCII equivalents, ensuring better compatibility and readability.
- **Integrated MQTT Broker**
- To enable the MQTT broker, set `"mqtt_broker"` to `true` in the `dev.json` configuration file.
- Note that the MQTT client will be disabled when the local broker is active. The Broker itself handles all messages like a client.
- Please be aware that this implementation does not support authentication or TLS encryption.
- **MQTT Placeholders in Custom Apps**
- This feature is particularly useful for users without a smart home system. Combined with the local broker, it eliminates the need for an external system to display data, such as from an inverter wich can send its data vie MQTT. Simply create a `[AppName].json` file in the CUSTOMAPP folder with your custom app JSON keys. This JSON file will be loaded upon boot, so you don't need to send it from an external source.
- Example usage:
```json
{"text": "Leistung: {{inverter/total/P_AC}}W"}
```
- The placeholders enclosed in `{{}}` will be replaced with the payload of the specified MQTT topic. Currently, there are no options available for formatting the payload.
