 Replying to [comment:5 vbraun]:
 > Do we have an official policy on how old a Sage version should still be
 able to upgrade?

 I declare "1 year" as the official policy, since that's the official
 policy for deprecation.  I think it is a reasonable amount of time.

 Since sage-4.5.3 had pipestatus, and was released 2010-09-08 and the next
 sage release won't be for two weeks (or so), it is fine to deprecate
 upgrading from pre sage-4.5.3 releases.
