KDE Plasma 6 is successor to KDE Plasma 5 created by the KDE Community. It is based on Qt 6 and KDE Frameworks 6 and brings many changes and improvements over previous versions. For Fedora Linux, the transition to KDE Plasma 6 will also include dropping support for the X11 session entirely, leaving only Plasma Wayland as the sole offered desktop mode. X11 applications are still supported, however. See the Feedback section on the link:++https://fedoraproject.org/wiki/Changes/KDE_Plasma_6#Feedback++[Change page] for details.
