Plasma 6.8 enters beta: the first Plasma with no X11 session, landing on October 14
The Wayland-only switch is official: no X11 session at login, with XWayland carrying old apps. The beta adds kup as Plasma's backup tool, pushes Union theming into QtWidgets apps, and builds out the remote-desktop stack, with the X11 session supported into early 2027 for anyone not ready.
