Wine is the compatibility layer that allows you to run games and applications developed for Windows - on Linux (plus also macOS and BSD). A new biweekly development release is out now with Wine 7.8. It's a major part of what makes up Steam Play Proton and enables a ton of games to work on the Steam Deck. Once a year or so, a new stable release is made.
Here's what they listed as the highlights in Wine 7.8:
- X11 and OSS drivers converted to PE.
- WoW64 support in the sound drivers.
- Number formatting using the new locale database.
- Various bug fixes.
Since it's sometimes asked: the continued conversion of various modules to PE is another change that will gradually increase compatibility in many ways over time for certain expected behaviour needed by Windows applications. Previously Wine has built its Win32 libraries (like DLLs and EXEs) as ELF but for many reasons (like better compatibility) they've started to move them over to use PE instead.
With this release 37 bugs were listed as solved like issues for: Assassin's Creed IV - Black Flag, Guilty Gear XX #Reload, The Evil Within, Command and Conquer Generals and various other miscellaneous fixes.
If you're looking for help managing Wine, I can happily suggest you go take a look at Bottles. Great software that really helps deal with it all.
