KDE Community announced release of KDE Plasma 5.4.0, latest stable release of popular open source desktop framework.
Plasma 5.4.0 is shipped with a lot of improvements like better DPI support, auto completion feature KRunner and many new beautiful Breeze icons. It also includes a preview for upcoming Wayland sessions.
More from release announcement:
With Plasma 5.4 the first technology preview of a Wayland session is released. On systems with free graphics drivers it is possible to run Plasma using KWin, Plasma's Wayland compositor and X11 window manager, through kernel mode settings. The currently supported feature set is driven by the needs for the Plasma Mobile project and more desktop oriented features are not yet fully implemented. The current state does not yet allow to use it as a replacement for Xorg based desktop, but allows to easily test it, contribute and watch tear free videos. Instructions on how to start Plasma on Wayland can be found in the KWin wiki pages. Wayland support will improve in future releases with the aim to get to a stable release soon.
