 ### General
-- Renamed cli argument `--list-devices` to `--info` as it evolved into a more generic way of showing dynamic information on configured sinks (such as available profiles in case of OpenRGB or file names in the `RelativeTo` directory of the Wallpaper sink)
+- Rename cli argument `--list-devices` to `--info` as it evolved into a more generic way of showing dynamic information on configured sinks (such as available profiles in case of OpenRGB or file names in the `RelativeTo` directory of the Wallpaper sink)
+- Parameter `--config` is no longer required. If not provided, the default config file `allmylightsrc.json` will be assumed in the same directory where the executable resides.
 
 ### OpenRGBSink
 - The OpenRGBSink now supports loading of profiles. Any string ending in `.orp` consumed by the sink will be sent as a load profile request to your OpenRGB instance.

 Given that you are looking at this page, you probably have a smart home framework in place already and want to integrate with it. Chances are that you are using MQTT as part of that setup. In that case you can go ahead and skip the rest of this section. If you're using a smart home framework without MQTT, please refer to the following resources for getting your MQTT server started and integrated.
