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 16.04/18.04/18.10/19.04 () and . Project Code licensed under GPLv2.
Among the changes, the expansion of the MirAL layer (Mir Abstraction Layer) is noted, which can be used to avoid direct access to the Mir server and abstract access to the ABI through the libmiral library. MirAL has added support for the application_id property, implemented the ability to crop windows in accordance with the boundaries of a given area, and provided support for setting environment variables by mir-based servers for launching clients.
Implemented output to the log of information about supported EGL and OpenGL extensions. For Wayland, the third version of the xdg protocol is used to solve problems with Xwayland. Hardware platform-specific components have been moved from libmirwayland-dev to the libmirwayland-bin package.
The mechanism for working together with memory has been changed, which made it possible to get rid of the use of the specific mir interface in snap packages.
