KaOS is very proud to announce the availability of the February release of a new stable ISO image. This release brings the end of KDE 4 as the default Desktop Environment for KaOS. Almost ten months ago work started to fully migrate to Frameworks 5, Plasma 5-based distribution and with the release of Plasma 5.2.1 this migration is now deemed ready to bring a better user experience then KDE 4. From the unset of this migration there was never a plan to mix the two environments. What you will see on this ISO is a pure Plasma 5-based environment. As many might have noted KDE Applications 14.12 did not contain more then a handful of Plasma 5 applications. Just about all applications that users have become used to seeing in a KDE 4 version are available as a Plasma 5 port. A few are not ready yet, and those will be missing from the KaOS repositories until their ports are ready for daily use.
