Unattended-upgrades starts upgrading packages in Devel 21 days before the release

Dear Disco Lovers,

With the Final Release approaching and new intrusive changes hopefully
not landing anymore we need to get feedback about how the unattended
application of updates work and give it a test flight.

After a series of discussions in the Foundations Team we implemented

which is hoped to be the sweet spot between running it during the
whole development period and turning it on right after the release
without wider-scale testing.

Migrating Bazaar repositories to Git on Launchpad

Dear Ubuntu Contributors!

Launchpad already supports git but there are still many active bzr
repositories there.

If you would like to migrate some of them to git I'd like to suggest
taking a look at bzr-git-mass-convert [1] based on bzr fast-export
(verifying the result with git-remote-bzr).

Supporting LZ4 as initramfs compressor


Initramfs-tools uses gzip compression by default which served us well
for quite some time but LZ4 offers way faster decompression while
making a only slightly bigger initramfs files.

On my old laptop the initramfs extraction time decreased from ~1.2s to ~0.24s:
