The Wine team has put out a second Release Candidate for what will eventually turn into a Wine 7.0 stable release in early 2022. This is the compatibility layer that allows you to run games and applications developed for Windows - on Linux. Part of what makes up Steam Play Proton.
Since it's now in a code-freeze, no new features are being pulled in while they work through any bugs and regressions that appear. Wine 7.0 RC2 release notes mention 34 bugs solved including issues for: Weird Worlds: Launcher, Death to Spies: Moment of Truth, Shadow Warrior, Resident Evil 4 HD, Her Story, Borderlands GOTY Enhanced, Dark Souls: Remastered, Steel Division: Normandy 44, Final Fantasy XIV, Sonic Adventure DX and more.
Going by past releases of Wine, we're probably looking at 5-7 RC builds before Wine 7.0 is released officially.
We expect that early next year Valve will also update / rebase Proton onto the 7.x series of Wine.
