Choose Stable Plasma 4 or Tech Preview of Plasma 5

Plasma 4 is our recommended stable offering and what you get from the default download, but is now in maintenance mode. It runs the software you are familiar with and will be getting updates and bugfixes but not new features from now on.



Plasma 5 a work in progress. The next generation of KDE Software is still a work in progress. You can test it and install it from the Kubuntu Plasma 5 image but beware it will remove your stable software.

KDE Applications and Platform 4.14


The KDE Applications and Platform 4.14 includes a bunch of bugfixes.

Plasma 5

This is the first Beta release of our Technical Preview of Plasma 5. It has plenty of known bugs, see below, and is only available for amd64, but also plenty of lovely new features. The Plasma 5.0 release announcement has more information.
