Currently in a feature-freeze while as many lingering issues are solved as possible for the next big stable release, Wine has a fourth Release Candidate up now.
What is Wine? It's a compatibility layer for running various Windows-only applications and games on Linux and other operating systems. Tons of people work on it, with some sponsored or employed directly by CodeWeavers who have their special version with the CrossOver application. Wine is also the backbone of Steam Play Proton.
As of this update the team noted 29 bugs solved. Our usual reminder: in Wine release announcements the list of bugs fixed isn't always those fixed with this release, it's often older bugs that finally saw someone confirm it was solved at some point. In the list checked off it mentions issues solved for: Children of Morta, Settlers III, World of Warships, Battlefield 3, Assassin's Creed IV Black Flag, Kingdom Come Deliverance, World of Warcraft Classic, Elite Dangerous Horizons and more.
