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.

Google has published their proof-of-concept code showing the practicality of Spectre exploits within modern web browsers' JavaScript engines. The code is out there and you can even try it for yourself on the leaky.page web-site.

Google's Leaky.Page code shows its possible to leak data at around 1kB/s when running their Chrome web browser on a Skylake CPU. The proof-of-concept code is catering to Intel Skylake CPUs while it should also work for other processors and browsers with

Another feature tacked onto the big GNOME 40 desktop update is a headless native back-end for Mutter and the ability to easily create virtual monitors.

This headless native back-end that was merged today into GNOME 40's Mutter allows for running the native back-end atop a render node in a headless configuration without a physical display attached. As part of this headless native back-end is also the ability to create virtual monitors via command-line options for debugging and other purposes. This also allows creating
