SteamOS 3.9.0 Preview

What I can see from this release is that SteamOS is being converted from device firmware into a general-purpose distribution that happens to boot into a game launcher. Quite a bit of a version jump in the dependencies as well.

Once KDE 6.8 is released, Valve must add Wayland support for Steam client and Proton/Wine. Also, they should drop 32-bit dependencies for Steam client on Linux, which has been done for Windows and macOS long ago.

My steam deck has been my main dev pc for a year now. Also serves Qwen 3.5 9B when I use my MacBook Air. Distrobox prevents OS updates from clobbering my environment.

Nice, they are quite close to upstream.
