KDE Plasma 6.8, scheduled for release Oct. 14, will become the first version of the desktop environment to operate exclusively on Wayland, removing the X11 desktop session entirely. The transition coincides with the KDE project's 30th anniversary.
Prior versions, including Plasma 6.7, offered X11 as an optional installation. With 6.8, Wayland becomes mandatory, though X11 applications will continue to run via XWayland compatibility layer.
The shift reflects a broader Linux infrastructure transition underway for a decade. X11, the display server protocol that has dominated desktop Linux since the 1980s, is aging and increasingly difficult to maintain. Wayland, designed as its successor, offers better security boundaries, lower latency, and cleaner architecture—but the migration has been slower than the open-source community anticipated, partly because enterprises maintain heavy X11dependencies.
KDE's decision to drop X11 entirely is significant because KDE serves both desktop users and embedded systems. The forced upgrade will likely accelerate Wayland adoption across the ecosystem, though it will create friction for users running older hardware or specialized applications that rely on X11-specific behavior.
In parallel, KDE is advancing the Union theme engine, which now offers preliminary support for styling QtWidgets applications including Dolphin and Kate. The revived Oxygen theme is receiving refinements for the 6.8 release.
KDE is also publishing a feature-length documentary about the project's 30-year history, produced by video company Cult.Repo.
A new project called Klassik recreates the KDE 3 desktop experience within Plasma 6. Klassik is not a port of the original KDE 3, which ended at version 3.5.10 in Aug. 2008. Instead, it reimplements the early-2000s panel, K Menu, Quicklaunch, Task Manager, and classic clock using modern Plasma 6 technologies, Qt 6, and KDE Frameworks 6. This approach preserves the historical user interface while supporting Wayland and fractional scaling.
