F-11 branched some time ago, and the current "devel" branch
rawhide. As the F-12 release date gets closer, you will first have
the option to request an F-12 branch (an announcement will be sent
when this happens) and then, a bit later, all packages will acquire an
F-12 branch (which will be accompanied by an announcement and some
downtime). This happens much later in the release cycle, though;
nothing will happen for a few months.
Now as I see a f-12 branch in common/branches how do I request that
one - the normal way via the package's bugzilla entry from the
packaging request (which was this spring) or is there another way for
requesting the new branch for the new release?
