It’s a branch.  It’s not in the manual because it’s just an operational
detail of how we use the build farm at hydra.gnu.org.

Rebuilding the Python package would result in a forced rebuild of all
dependent packages.  Our build farm isn’t fast enough to rebuild that
much in time, so we would have an uncomfortable window during which a
lot of packages would have to be built from source.  By having a
separate branch for updates that cause a lot of rebuilds we can build
substitutes in the background.  Once most of the substitutes have been
built we merge “core-updates” into “master”, so that people upgrading to
latest master will be able to download substitutes.
