Mir 2.2 Released with Support for Software Buffers on X11, Wayland, and GBM/KMS

Developed by Canonical, Mir aims to offer a display stack that currently aims to provide a Wayland compositor designed ti make the transition from X11 to Wayland a breeze for many users. It’s a well-tested and performant platform that’s being actively used in the Ubuntu Touch mobile OS from UBports. The new release, Mir 2.2, comes with better VM compatibility by implementing support for software buffers on X11, Wayland, and GBM/KMS, the ability to add and drop Wayland extensions, composite-bypass for Wayland clients, and improved handling of the DRM_FORMAT_MOD_INVALID Wayland extension.
