have made a new image for the Rpi 3 and Rpi 4.
You'll find it here:
This is what Capsia wrote in the release note:
Hi! I finally have a focal image for the Pi. Please note that this is still in very early development and there may be issues. Currently known issues are that video playback does not work in the video app (only in the browser), the first boot is very slow and the Pi 3 is quite laggy with only 1GB of ram. This image has also been tested and works on the Pi4, other models such as the Pi400 may or may not work.
