Latest version of Canonical's Wayland compositor arrives
Canonical is still working away on its own Mir display server, used in several of its IoT product lines. Version 2.14 gains more functionality useful for full desktop environments.
Mir is a complex project which has undergone some big changes over its more than a decade of existence, and it has several subprojects now, including the Lomiri desktop, which not only natively runs on Debian but is included as part of Debian 12.
Mir 2.14 – that's version 14 of Mir 2, not version two-point-one-four – is out, and supports a larger range of Wayland functionality. The announcement says this release brings support for Wayland screenlockers (the ext-session-lock-v1 Wayland extension protocol), and support for Drag 'n Drop, which also means that "attached" windows can be "restored"" by a drag gesture. It has improved nVidia hardware support, and fixes an evdev handling bug.
Since version 2.0, Mir has been a pure Wayland compositor, although the fondleslab version still uses the older Mir 1.8, because that also supports the older mirclient APIs. In fact, it's not so much a Wayland compositor; as lead developer Alan Griffiths told The Register: "Mir is a set of libraries for building Wayland compositors."
He went on to say: "There are a number of projects that use these libraries, the most significant being Ubuntu Frame, Lomiri and Miriway."
