As a general principle, I think you should only bother to guarantee
save-file compatibility between released versions. That's not to say
it should never be implemented in other case, but probably only when
it's really easy and doesn't cause code bloat.  People tracking CVS
should be happy to lose games (or finish them in a given version).
