Dependency and runtime upgrades
Take the batch bumps, the framework major, and the upgrade leftovers off the release path.
Old versions stay invisible until the day they block a release. Then they block everything at once.
These go in stages, starting with the safe batch and then taking the major versions one at a time, with the tests passing before the next one starts.
