KaOS is an interesting and very efficient Linux distribution built around a refined KDE desktop environment. The KDE integration is much more controlled in KaOS than in other Linux choices. The latest release for this 14-month young Linux distro came in late June. KaOS is a bit of a rarity. It is independent of other distros -- not a direct relative of other Linux offshoots. That means it does not rely on repositories developed and maintained by larger Linux communities.
