Ubuntu's Mir 0.13 Display Server Receives a Major Update, Mir 0.14 on the Way

Canonical's Cemil Azizoglu sent in his regular report to inform us all about the new features that were implemented in the third maintenance of Mir 0.13, the next-generation display server for the Ubuntu Linux operating system.

Mir 0.13.3 was released on June 26, as reported by Cemil Azizoglu, and it is a major maintenance version that brings important new features, various under-the-hood improvements, and fixes many of the bugs reported by users since the previous release.

According to the release notes, which have been attached at the end of the article for reference, Mir 0.13.3 come with double-buffering support, new proposals for the "Application not responding" and Mir-on-X branches, as well as fixes for fd leaks in various tests.

Some more work was done to improve buffer semantics, as well as to clean up MirEvent, and to enhance QtMir to make use of the WM interface. During the cleanup, some deprecated Mir code got removed.

Last but not least, the Mir team started work on evaluating the Vulkan/WSI API (Application Programming Interface) and on coordinating the changes that have been implemented lately in the libinput library with upstream.

The Mir 0.14 release is coming very soon

In addition to the changes mentioned above, the Mir team also informs users that work has started on a Python-based perf test framework implementation, which should land in the next major release of Ubuntu's next generation display server.

In some more good news, it has been announced that Mir 0.14 is coming very soon, but until then, all users are urged to download Mir 0.13.3 right now and start testing it. Don't forget to report bugs on the usual channels.
