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. > And why is a minor update in "core-updates" and not on the main-line? 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. ~~ Ricardo
