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 changes include an expansion of the MirAL (Mir Abstraction Layer), which can be used to avoid direct interaction with the Mir server and abstract access to the ABI through the libmiral library. The MirAL now supports the application_id property, enables window cropping according to specified area boundaries, and provides support for Mir-based servers to set environment variables for launching clients.
Information about the supported EGL and OpenGL extensions is now logged. For Wayland, the third version of the xdg protocol is utilized to address issues with Xwayland. Platform-specific components have been moved from libmirwayland-dev to the libmirwayland-bin package.
The memory cooperation mechanism has been modified, eliminating the need for the specific mir interface in snap packages.
