This week in Mir we’ve got the https://community.ubuntu.com/t/mir-0-32-0-release/6774 actually released! Headline features include better Wayland support and the long-anticipated support for claiming devices via logind, allowing Mir shells to be easily run from GDM.
Due to new mesa features the mesa-kms platform currently doesn’t work on Cosmic, but this should be fixed soon.
Happy Miring!
