Mir 2.13.0 Release

We’re pleased to announce the release of Mir 2.13.0.

This release brings some updates to the versions of Wayland protocols (wl_output and XDG shell) and a bunch of features around display configuration.

Display configuration

Mir has long supported a .display configuration file for specifying one or more layouts of screens. This has been enhanced to:

  • inititialise the content of this file with alternative layouts;
  • pick up changes to the file without restarting the server; and,
  • allow changing the selection of alternative layouts (also without restarting the server)
