Mir release v2.20.1

Project Discussion Mir

We’re pleased to announce the release of Mir 2.20.1. This includes bugfixes and improvements in a number of areas.

Lomiri support

Lomiri, the descendant of Unity8 of the Ubuntu Phone, can run on bleeding edge Mir again through updates to miroil and QtMir.

LxQT session

We worked with the LxQT community to enable using Mir(iway) as their Wayland compositor.

Focus stealing prevention

Shells can now enable (miral-shell’s example) requiring windows to activate themselves with the xdg_activation_v1 protocol when opening new windows. This prevents them from popping up windows while you’re interacting with another.

Accessibility

Key delay and repeat are now configurable, making our first step in accessibility.
