Wine 6.23 is out now continuing the PE conversion work

By - | Views: 15,348

Another two weeks and more fixes coming in, the Wine 6.23 release is officially out now with new features and bug fixes.

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. Once a year or so, a new stable release is made which will be Wine 7.0 likely in January 2022 and the Release Candidate stage for Wine 7.0 will begin soon.

Here's the Wine 6.23 release feature highlights:

  • Mount manager and CoreAudio driver converted to PE.
  • Support for exception handling in Wow64 mode.
  • Optional support for using the distribution's PE libraries.
  • A number of UI improvements in WineDbg.

As we explained previously: 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.

For big fixes 48 were noted as fixed including issues solved for: Internet Chess Club, Layers of Fear, Rockstar Game Launcher, GTA 1997 autorun, a fix for joysticks and various miscellaneous bug fixes.

That is some serious game preservation effort done here

I don't understand the whore PE-push, are the wine devs essentially saying that native Linux executable formats are subpar for executing code on Linux, or is there some super-optimzed PE-to-ELF translation layer at work here?

Compatibility with Windows essentially:

*** PE modules

- Most modules are built in PE format (Portable Executable, the
  Windows binary format) instead of ELF when the MinGW compiler is
  available. This helps various copy protection schemes that check
  that the on-disk and in-memory contents of system modules are
  identical.

- The actual PE binaries are copied into the Wine prefix instead of
  the fake DLL files. This makes the prefix look more like a real
  Windows installation, at the cost of some extra disk space.

- Modules that have been converted to PE can use standard wide-char C
  functions, as well as wide-char character constants like L"abc".
  This makes the code easier to read.

I'm still waiting for this to be fixed (the complication was caused by PE migration):

It's important for Cyberpunk 2077.

Wow, seems like an important regression potentially impacting audio chats or even proaudio apps...
am I right?

I haven't experienced it anywhere but with CP2077, but I guess anything where audio priority is important can be affected.
