Amber commented that using milestones for such a thing is not a good idea and that we should use tags like: landed-in-15.5, landed-for-15.5 ... and keep milestones like Python-3 unchanged.
I think rather than having a tag, it would make more sense to have a custom field (http://trac.edgewall.org/wiki/TracTicketsCustomFields). I do think using `next` as the version before a release makes sense. One thing to note with that, is that tickets that land between branching and a release shouldn't have the fix version updated.
