With Weston 12.0 there are tons of changes that have built up in the code-base since the release of Weston 11.0 last September. There is support for tearing-control and other new protocols, initial multi-GPU support, and a lot of other features for this next version. Some of the Weston 12.0 highlights 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 added that is based on the PipeWire plug-in.
- 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.
- Documentation updates.
