The popular Wine Windows-API re-implementation for running Windows software on non-Windows machines has had a severe lack of support for Korean Unified Hangul Code (UHC), also known as extended Wansung, encoding for too long. Wine finally gained support for the UHC codepage 20949 with the release of Wine 6.4 thanks to a valuable contribution from Sanghoon Park (박상훈).

There's also new support for Datagram Transport Layer Security (DTLS) in Wine 6.4. DTLS is not that widely used today due to problems like packet reordering and other issues DTLS has as a consequence of it being based on the UDP protocol. There are some use-cases, so it is quite nice that Wine is now properly able to handle Windows-applications using DTLS.

Wine has also gained a new dialog for editing Access Control entries.

There is a total of 38 bug-fixes since Wine 6.3 in this release. Most of them are game/application-specific. Programs that have specific fixes for them in Wine 6.4 include Civilization IV Beyond the Sword, Canon MP Navigator EX 4.x/5.x, Acrobat Reader XI, Soldiers of Anarchy, The Elder Scrolls V: Skyrim SE, Entropia Universe, Horizon Zero Dawn, Serious Sam 4, Final Fantasy XI Online, The Suffering and notepad.

The top contributors to this fine release were Nikolay Sivov (65), Zebediah Figura (55), Alexandre Julliard (50), Jacek Caban (38), Huw D. M. Davies (23), Hugh McMaster (22) and Zhiyi Zhang (15). All the top five contributors are employed by the Codeweavers corporation.

Wine certainly seems to get better with age.
