You might be using a slightly different workflow from Peter and Richard,
I don't think this ever happened before. But that's totally fine, I'll
change the job to behave better in that case.

Yes, but since that one commit does not have any code anyway, we've
decided to just let it run on the same version. The very next commit
will be aligned again. Still, the time-of-tag issue was indeed an
oversight.

Will do, thanks!
