You will not find Plasma or Kwin on this ISO, though KaOS has always been a KDE Plasma only distribution. Instead, you will find a niri/Noctalia based system. For those wondering why this change, it has come into play because of a desire to move away from systemd. Work is ongoing to see if a move to Dinit is viable for this distribution, that also meant, looking for an alternative to Plasma, since Plasma pretty much demands systemd, and will be fully mandatory soon. This ISO still uses systemd fully though. Trials to use niri with the Noctalia shell have proven to be a nice option. Using these means, KaOS can stay a Qt focused distribution. This ISO is still GTK free, still ships Qt/KDE based applications. The change for this ISO however doesn't mean it is permanent. Plasma 6 is still fully available in the repositories. Using an ISO though for wider testing and gauging general response for such a move, was deemed a needed option.
