Wine 6.4 is out today as the newest bi-weekly point release for running your favorite Windows applications and games on Linux, macOS, and other platforms.
Wine 6.4 brings initial DTLS (Datagram Transport Layer Security ) support to the Secur32 code. DTLS provides similar security to TLS while being designed for datagram-based software with UDP. DTLS on Windows is used by software like Cisco AnyConnect, OpenConnect, NetScaler, and can also be used by browsers like Google Chrome and Firefox for WebRTC.
Wine 6.4 also brings Fontset support to DirectWrite, a dialog for editing Access Control entries, theming support for some more common controls, support for the Korean Wansung encoding, and 38 known bug fixes. The bug fixes in this release affect software ranging from NVIDIA PhysX to games like Soldiers of Anarchy, Final Fantasy XI Online, and The Witcher 3.
