    - Add debian/sbat.csv.in

  [ Dimitri John Ledkov & Steve Langasek LP: #1915536 ]
  * Allow grub-efi-amd64|arm64 & -bin & -dbg be built by
    src:grub2-unsigned (potentially of a higher version number).
  * Add debian/rules generate-grub2-unsigned target to quickly build
    src:grub2-unsigned for binary-copy backports.
  * postinst: allow postinst to with with or without grub-multi-install
    binary.
  * postinst: allow using various grub-install options to achieve
    --no-extra-removable.
  * postinst: only call grub-check-signatures if it exists.
  * control: relax dependency on grub2-common, as maintainer script got
    fixed up to work with grub2-common/grub-common as far back as trusty.
  * control: allow higher version depdencies from grub-efi package.
  * dirs.in: create var/lib/grub/ucf in grub-efi-amd64 (and similar) as
    postinst script uses that directory, and yet relies on grub-common to
    create/ship it, which is not true in older releases. Also make sure
    dh_installdirs runs after the .dirs files are generated.

grub2 (2.04-1ubuntu41) hirsute; urgency=medium

  * No-change rebuild to drop the udeb package.
