The release of the display server Mir 2.7 is presented, the development of which continues by Canonical, despite the refusal to develop 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 are prepared for Ubuntu 20.04, 21.10 and 22.04-test (PPA) and Fedora 33, 34, 35 and 36. The project code is distributed under the GPLv2 license.
The new version includes the MirOil library, which provides a layer for transferring the Lomiri graphical environment to new versions of Mir, which continues the development of the Unity8 shell. Added "idle-timeout" option to set the screen to turn off after a certain amount of time of inactivity. Added support for the zwp_text_input_manager_v2 protocol, which is in demand in on-screen keyboards and Qt applications. Improved input focus management for the keyboard. The development has been switched to the C++20 standard.
