Plucky Puffin (to be 25.04) Beta Freeze

[Paride Legovini]

As of a short while ago, Plucky has entered the Beta Freeze, with a goal
of releasing Beta images sometime late Thursday. *From now until the
Beta is released, please only upload updates for packages on any release
images if you /need/ to get them into the Beta itself.* Please hold off
with everything else until after we release on Thursday.

The queue freeze will last from now until the final release next month,
which means that all seeded packages will now need a spot-check and
review in the queue from a release team member before they are let into
the archive.

As with the previous releases, we have a bot in place that will accept
uploads that are unseeded and don't affect images. Don't take this as an
open invitation to break Feature Freeze on those components, this is
just to reduce the burden on the release team, so we only review the
uploads that need very serious consideration. If you find the bot is
blocking an upload that you think should have been auto-accepted, let us
know and we'll sort it out.

We have spun a set of Beta candidates already. We encourage people to
start testing ASAP for their favorite flavor(s) as they come off the line.

Happy bug-hunting from now until the final release, and please do help
out and test images, etc, where you can and let us know what's broken in
your environment(s).

As a reminder, the Beta images will appear on the ISO Tracker here:
