The Kubuntu team have been working hard to ship 25.04 with the latest Qt6 based Plasma 6.3 KDE desktop.

Included is Plasma 6.3 which is the fourth feature release of the 6 series.

More details of what was new with Plasma 6 can be found in the original announcement for the first 6.0 release.

Plasma Wayland session

The Plasma Wayland session is now the default option in SDDM (display manager login screen). An X11 session can be selected instead if desired. The last used session type will be remembered, so you do not have to switch type on each login.

Kubuntu 25.04 Beta ships with Qt6.8 and KDE Frameworks version 6.12.0.

For applications that are still based on Qt5/KF5, Qt5 5.15.15 and Frameworks 5.116.0 are still in the archive.
