KDE Plasma 6.8 is scheduled for release on October 14, 2026, to coincide with KDE's 30th anniversary, featuring a new theming system called "Union" that enhances styling for both native QtQuick and classic QtWidgets applications. Development for Plasma 6.9 has already begun, although it is in the early stages with limited features introduced so far. The upcoming 6.8 version will mark the transition to a Wayland-only desktop, phasing out dedicated X11 sessions, while the 6.6 LTS line will remain supported until 2029 for those prioritizing stability. KDE encourages community involvement by testing live images and reporting bugs ahead of the release

KDE Plasma 6.8 Ships October 14 for KDE's 30th Anniversary

KDE Plasma 6.8 is set to launch on 14 October 2026, deliberately timed to land on KDE's 30th anniversary. The star of the release is the "Union" theming system, which now extends styling to classic QtWidgets apps like Dolphin and Kate. At the same time, 6.9 has already entered early development with no beta and only a handful of features merged so far. Plasma 6.8 also closes out KDE's transition to a Wayland-only desktop, while the 6.6 LTS line remains supported until 2029 for stability-focused users.
