As its name suggests, KaOS is built around the KDE desktop environment, so it’s targeted mainly at KDE fans. The new ISO image, KaOS 2017.02, ships with all the latest KDE technologies and applications, including KDE Plasma 5.9.2, KDE Applications 16.12.2, KDE Frameworks 5.31.0, and Qt 5.8.0. Few know that the developers behind KaOS also contribute to the popular and open-source Calamares universal installer framework that’s being used as default install by many other GNU/Linux distributions, and today’s KaOS 2017.02 install medium ships with Calamares 3.1, which is currently still in development.
