Valve shipped SteamOS 3.8.13 to stable on July 1, fixing a Final Fantasy VII Rebirth crash-on-launch bug and a controller firmware update failure.

Valve quietly built AMD's FSR 4.1.1 upscaler into Proton Experimental, auto-upgrading any FSR 3.1 game on RDNA 3 hardware — including the Steam Machine's GPU, in the same week the console started shipping.
Diablo IV's Season of Death Awakening launched on July 1 and immediately broke Proton compatibility — the game quits a few seconds after launch on Steam Deck and SteamOS. Blizzard's first emergency patch didn't fix it, and a second attempt is coming.
