Xfce 4.20 Will Keep X11 Support, Brings Wayland to the Scene
The Xfce developers have refreshed their roadmap to incorporate Wayland protocol support. The plan now includes initial support for Wayland in the core components of the forthcoming major release of Xfce 4.20 while continuing to support X11.
Previously, the issue of maintaining backward compatibility with X11 was discussed, but no consensus was reached. But it has now been decided that X11 support will not be discontinued in the foreseeable future.
The Wayland session in Xfce 4.20 will cover a minimally necessary set of features, with the intention of gradually adding missing functionality in preparation for subsequent releases. Efforts will continue to refine the performance of already ported user applications in the Wayland-based environment.
