I was looking through What's New in Python 3.2 (because of this question), and I found:

The random.seed() function and method now salt string seeds with an sha512 hash function. To access the previous version of seed in order to reproduce Python 3.1 sequences, set the version argument to 1, random.seed(s, version=1).

It appears to be a breaking change (from 3.1 to 3.2) with a backwards compatibility option.

(As borrible pointed out, because a compatible seeder is offered the documentation contract has not been violated.)
