Some very nice improvements made but Nvidia GPU users will have to enable the hardware acceleration themselves and test that it is not crashing the X11 display system.
Also for Linux users, the new stable Steam Client update adds a new Compatibility tab in Settings to let you more easily change SteamPlay/Proton settings, improves support for Flatpak apps when listing or adding them as non-Steam shortcuts, and adds the -forcedesktopscaling command line switch to override the window scaling factor.
