I can't see us ever wanting to do more than one release a day on average
(i.e. I can see the need to update a release on the same day, but that
would be rare), so we want to allow for up to 366 releases per year.
So why not change the sequence to go a to y, then zaa to zzz? That way you
never have one ID being the prefix of another.
