Wine adds a compatibility layer on Linux, macOS or BSD operating system, allowing users to run applications and games that are designed only for Microsoft Windows OSes, and Wine 2.0 will be out soon as the newest major release of the open-source software, but, until then, you’re invited to test drive the fourth RC build. It’s been a little over two weeks after the release of Wine 2.0 RC3, but it looks like the development team was pretty busy fixing the last remaining blockers before Wine 2.0 hits stable. The release notes show us that a total of 28 bugs reported by users have been addressed in the Wine 2.0 RC4 snapshot.
