Weston 12.0 as Wayland's reference compositor is now available with multiple GPU support in the DRM back-end, support for HDMI content types, support for the Wayland tearing control protocol, plane alpha DRM property handling, a PipeWire back-end, and much more.

Some of the highlights for today's Weston 12.0 stable compositor update include:

- Support for the tearing-control protocol to let clients request to be flipped asynchronously. This can allow tearing if so desired.

- A PipeWire back-end has been merged.

- Multi-GPU support for running a single Weston instance with multiple DRM devices. This adds a new "--additional-devices" option when launching Weston.

- Basic drawing tablet support for Weston.

- Various debugging and profiling improvements.

- Various XWayland compatibility fixes, including to not leak file descriptors on failures.

- Many random DRM back-end updates, including support for the plane alpha DRM property.

- Initial multi-head support for the RDP back-end.

- Weston's Wayland back-end now allows resizing support for XDG-Shell to allow resizing the Weston window on another Wayland compositor.

- xwayland_shell_v1 protocol support.

Wayland/Weston has come a long way since its early days... Picture is back at XDC2012 with Wayland founder Kristian Høgsberg.
