Tag2upload is now ready for experimentation

Debian's long-awaited tag2upload service is
now ready for Debian maintainers to use in some circumstances. Tag2upload makes it easier for maintainers to upload packages, by allowing them to push a signed Git commit that will automatically be picked up and built, instead of pushing a build from their local machine. LWN covered the
discussion around the service in July of last year. With the timing of its readiness, it's likely to become more useful once Debian 13 ('trixie') is released.

Be very aware of the freeze! Do not just upload to unstable as
your first test! Uploads to unstable, targeting trixie, can be
done with tag2upload - but in most cases you will probably want to
upload the same package to experimental first.
