We should probably use git to tag a release, and then provide 2 links on the website: (1) zipball for the tagged release (something like https://help.github.com/articles/linking-to-releases/) and (2) zipball for master.
(2) is easy to do right away because it already exists: https://github.com/imneme/pcg-c/zipball/master.
(1) requires creating a tagged commit, then pushing it here, and then linking it using the 'zipball' syntax somehow.
I just think it's better to do this as it is more automated and also offloads the storage/bandwidth (however trivial) from pcg-random.org to github.
