I have been using this for a couple of weeks and it has been very stable. Other than xfwl4 itself, the rest of the desktop has been the released XFCE 4.20 components. Already it is a better way of running XFCE on Wayland than using something like labwc I would say.

It is great to see a release. Hopefully more people will try it and give feedback so it can get into XFCE 4.22 by the end of the year.
