> 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.
