Wayland's Weston Compositor Introduces Kiosk/Fullscreen Shell
While there is already the Cage kiosk full-screen shell as well as the likes of Ubuntu's Mir Kiosk Shell, Wayland's Weston reference compositor now has its own implementation.
Collabora graphics developer Alexandros Frantzis has contributed "kiosk-shell" to Weston, Wayland's official reference compositor. The Kiosk Shell is a full-screen shell for applications making use of the XDG-Shell protocol.

ACO Radeon Shader Back-End Adds Unit Testing Framework To Help Test Optimizations
The popular "ACO" shader compiler back-end that recently was promoted to the default shader compiler for Mesa's open-source Radeon Vulkan driver (RADV) has long been testing with shaders and traces while now a proper unit testing framework is being introduced for verifying optimizations are correctly handled, ensuring no regressions, etc.
ACO continues on a nice upward trajectory this year with being the default over AMDGPU LLVM for the RADV driver in Mesa 20.2, Valve continuing to fund the developers working on it, RadeonSI OpenGL driver support still being worked on, and various performance optimizations continuing. For helping to keep on that trajectory, today a unit testing framework was merged for ACO.
