release of the display server , developed by Canonical, continues to thrive despite the abandonment of the Unity shell and the Ubuntu edition for smartphones. Mir remains in demand in Canonical's projects and is now positioned as a solution for embedded devices and the Internet of Things (IoT). Mir can be used as a compositor for Wayland, allowing any applications that use Wayland (for example, those built with GTK3/4, Qt5, or SDL2) to run in environments based on Mir. Installation packages are prepared for Ubuntu 16.04/18.04/18.10/19.04 () and . The project's code is licensed under GPLv2.
The new release includes optimizations to the code related to Wayland and introduces a new graphics platform called "wayland," which allows Mir to run as a client under another Wayland compositing server (such a server can include the miral-system-compositor provided with Mir). Switching between different sessions is done via Ctrl-Alt-PgUp/Ctrl-Alt-PgDn. This feature was the last piece needed to transition the UBports/Ubuntu Touch stack from mirclient to Wayland and to run Unity8 as a client of unity-system-compositor.
Additionally, an initial implementation of the rpi-dispmanx graphics platform is available for Mir, intended for use on Raspberry Pi. This includes new demonstration applications.
mir_demo_client_wayland_egl_spinner and miral-system-compositor. Build issues in Arch Linux have been resolved.
