First of all, happy new year! 🎆

This release contains a quite fundamental change on how Zigbee2MQTT handles unsupported devices.
Zigbee2MQTT will now attempt to automatically detect features supported by the device and discover those to e.g. the frontend and Home Assistant.
This means that if you, for example pair an unsupported light, there is no need to wait for official support. Basic features will work out-of-the-box.
The way to officially add support for devices has also been simplified due to this (docs). These changes have been made in #6692 and #20358.
