            Description

            trunk has a minimum software version of 3.0.0-alpha1. This means we can't rolling upgrade between branch-2 and trunk.

            This is a showstopper for large deployments. Unless there are very compelling reasons to break compatibility, let's restore the ability to rolling upgrade to 3.x releases.
