Changes in 1.2.1
================

 * Ensure flatpak builds with older versions of glib and appstream-glib.
 * build-commit-from: Fix the new --extra-id option.
 * build-export: Allow disabling the sandboxing of the icon validator and
   do so during the tests.
 * profile: Don't break if debug logging is enabled.
 * Better handling of the appdata release attribute.
 * Don't install polkit agent when not needed, avoiding some unnecessary
   log lines in some cases.
 * Fix the output of the sandboxed icon validator not being visible.
 * builld-init: Allow specifying a full ref for the sdk, which is used to
   select the branch name when checking sdk extensions.
 * Make the ok checks in the output green
