Mir 1.3.0 Release

Mir 1.3.0 Release

We’re pleased to announce the release of Mir 1.3.0.

For Ubuntu, Mir is available from the Mir PPAs. It is also available as a source tarball.

Wayland extension protocols

This release is mostly about supporting Mir based shells using additional Wayland extension protocols. It addresses a few of the issues encountered using libmirwayland-dev:

  • mirwayland.pc does not specify /usr/include/mirwayland #873
  • Add a package config file for mircommon and reference it mirwayland and mirplatform #868

It also makes it much easier to test Wayland extensions in a downstream project:

  • Publish miral::TestWlcsDisplayServer and miral::TestServer fixtures in mirtest-dev

Please note, however, that this support is a work in progress and, depending on any feedback we get, we may need to make improvements that are not backwards compatible.

A few days ago I published a “worked example” of a downstream project using these tools: https://discourse.ubuntu.com/t/work-in-progress-developing-wayland-extension-protocols-for-mir-servers/11609/
