Mir 0.31.0 release

We’ve kicked off the process to release Mir 0.31.0, the major things to note are:

  1. MirAL version 2.0
    We’ve taken the pending 18.04LTS as a good point at which to break the libmiral ABI and tidy up the API and, as a result, simplify the examples using it.

  2. Wayland xdg-shell
    Our Wayland support is still improving. And while it isn’t “done” we’ve decided that our support for xdg-shell V6 (unstable) is good enough to enable by default.

The candidate releases are available from the usual places:

On Ubuntu 16.04, 17.10 & 18.04

$ sudo add-apt-repository ppa:mir-team/rc
$ sudo apt install mir-demos

On Fedora 26, 27, 28

$ sudo dnf copr enable ngompa/mir-prerel-fedora
$ sudo dnf install mir-demos

One thing that didn’t quite make the release is an example mir-desktop-session. I mentioned this on the UBports forum but it isn’t ready. Work on this is in progress and will ship the next update.

We’ve now tagged and released Mir 0.31.0. It is in the mir-team/release PPA for Ubuntu 16.04, 17.10 & 18.04:

$ sudo add-apt-repository ppa:mir-team/release
$ sudo apt install mir-demos mir-graphics-drivers-desktop qterminal qtwayland5

The release tarball is here

Uploading to Ubuntu 18.04 “Bionic” will take a few days to complete.

An updated mir-kiosk snap based on mir 0.31.0 is now available in the snap store as well:

$ snap install mir-kiosk --beta

See https://developer.ubuntu.com/core/examples/snaps-on-mir for more information.

The release to 18.04 “Bionic” has completed: https://bugs.launchpad.net/ubuntu/+source/mir/+bug/1757952/comments/7

Users of the 18.04 pre-release will no longer need ppa:mir-team/release to get M ir 0.31.0.

Updated documentation on mir-server.io

Following on from the release of Mir 0.31 we have now updated the documentation on mir-server.io to reflect the MirAL 2.0 API changes.
