Xfce 4.20 is out with Wayland work in progress
Briefly

The new version of Xfce, 4.20, now enables Wayland use, featuring improvements like a faster Thunar file manager, but with known limitations.
Xfce 4.20 abstracts differences between X11 and Wayland to ensure identical functionality, acknowledging shortcomings, which many users found refreshing.
The Thunar file manager saw significant speed improvements and a new design approach similar to macOS, including streamlined navigation and enhanced icon options.
Despite exciting advancements, some users are still satisfied with the functionality of X.org, amidst mixed feelings about Wayland's adoption.
