Today, the next version of the stable Proton branch has released on the Steam Deck.

We have newly playable games like The Longest Journey, EverQuest 2, and Star Wars: Knights of the Old Republic 2, and a plethora of fixes that range from individual game fixes, like Baldur's Gate 3 displaying a dxdiag error, to Ship of Fools allowing other players to join your online session.
