display server release , which continues to be developed by Canonical, despite the abandonment of the development of the Unity shell and the Ubuntu edition for smartphones. Mir remains in demand in Canonical projects and is now positioned as a solution for embedded devices and the Internet of things (IoT). Mir can be used as a composite server for Wayland, which allows you to run any applications using Wayland (for example, built with GTK3/4, Qt5 or SDL2) in Mir-based environments. Installation packages prepared for Ubuntu 16.04-19.10 () and . Project Code licensed under GPLv2.
The new release mainly offers bug fixes related to experimental support for running X11 applications in a Wayland-based environment (using Xwayland). For X11, the ability to decorate windows has been implemented and an option has been added to override the path to the Xwayland executable. Cleaned up code related to Xwayland. X11 support will be removed from experimental status in one of the next releases.
The implementation of the "wayland" platform, which allows running Mir as a client under the control of another Wayland composite server (such a server can also be the miral-system-compositor provided in Mir), has been added support for configuring output scaling.
The optional ability to run applications based on the mirclient API instead of the Wayland protocol is still preserved, but has already been removed in the master branch (previously, the use of UBports and Ubuntu Touch prevented the removal of the mirclient API).
