The openSUSE Tumbleweed rolling release Linux distribution has begun rolling out the KDE Plasma 6.0.1, Gear 24.02 apps, and Frameworks 6.0 packages. Plasma 5 is being replaced within the Tumbleweed repository but openSUSE Tumbleweed isn’t yet transitioning to the Wayland session by default.
Endeavour’s current iso is still KDE 5 and X11, but if you do an online install it will default to 6 and Wayland. Just make sure to connect to the Internet before starting the installer.
