GitHub decided they do not want to host release downloads (they reversed the decision after that) AFAICT they haven't, at least i don't see any way to upload release tarballs. they certainly let anybody download tarballs generated for any annotated tag. but those tarballs are not immutable! once in a while, these tarballs start coming down with different hashes, presumably as github changes the code which generates those tarballs. that makes them less than ideal as package sources.
