Not an emulator but a compatibility tool that translates Windows calls into language Linux can understand, Wine 6.4 is officially out now as the latest development release.
For newer readers and Linux users here's a refresher - Wine is a compatibility layer built for operating systems like Linux, macOS and BSD. The idea is to allow other platforms to run games and applications only built and supported for Windows. It's also part of what makes up Steam Play Proton. Once a year or so, all the development is bundled into a stable release.
Here's what's new in Wine 6.4:
- Support for the DTLS protocol.
- Fontset support in DirectWrite.
- Dialog for editing Access Control entries.
- Theming support for a few more common controls.
- Support for Korean Wansung encoding.
There's also 38 bugs noted as fixed this time around. As usual some being quite old that were fixed a while ago, each release sees the team go over bugs to see what are still actually a problem. Like with this release a bug report from 2007 was finally marked as solved along with issues fixed for: Civilization IV, Soldiers of Anarchy, The Elder Scrolls V: Skyrim SE, Entropia Universe, Banished, Horizon Zero Dawn, Serious Sam 4, The Witcher 3 and more.
