Wine 6.8 isn’t the most exciting development release but one interesting low-level note is there is now support for loading libraries from architecture-specific subdirectories. Alexandre Julliard worked out the support so the likes of NTDLL, SETUPAPI and other components can load libraries from architecture-specific PE directories. The build system has also been updated for installing the PE files, fake DLLs, and related bits into architecture-specific directories. Similar to the architecture-specific subdirectories common to many Linux distributions for library handling, this can help out some workflows primarily for Wine developers as well.
