Windows Subsystem for Linux 0.65.1 is out to Insiders

A new version of WSL is now available to Insiders in all channels of Windows. The release is notable for several graphic stack improvements, includes the Linux Kernel 5.15.57.1, and more accurate time sync between Windows and Linux.

Windows Subsystem for Linux allows running Linux binaries right from Windows via a VM with very small footprint. It works much faster than a virtual machine, and doesn't require you to maintain a dual-boot setup. WSL is a welcome feature by advanced users and developer who create cross-platform projects. WSL works in Windows 10 and Windows 11.

With this release, Microsoft is testing a wide range of changes among Insiders to collect feedback and find if they are ready for the public rollout. On GitHub, there is the msixbundle file of WSL 0.65.1 that you can download and install. It comes with the following notes.
