KaOS 2015.02 was released.
"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."
KaOS is a desktop Linux distribution that features the latest version of the KDE desktop environment, the Calligra office suite, and other popular software applications that use the Qt toolkit. It was inspired by Arch Linux, but the developers build their own packages which are available from in-house repositories. KaOS employs a rolling-release development model and is built exclusively for 64-bit computer systems.
