@ -5,6 +5,11 @@ livecd-rootfs (2.466) UNRELEASED; urgency=medium
* move snap assertion handling into the generic build script (and, in
the process, from the subiquity overlay to the base squashfs).
* add ubuntu-mate to the set of projects we add snap model assertions to.
* Factor out grub-related diversions and use them consistently, so we
don't end up with wrong os-probe output in our grub.cfg.
* Fix the force-partuuid handling to create the file under
/etc/default/grub.d/ with a .cfg extension as grub expects; it's unclear
how this ever worked without.
