From Slack:

Jake: our reno config is assuming that a stable branch won’t have any unreleased updates if we’re making a new minor. or major
Matthew: We should probably strip the old branches from the release_notes.rst on stable/1.x and main
Jake: I guess with our current syncing process that probably works the best, yeah

Is this / can this be fixed on the docs side now 1.0.1 is out?
