We use tags for that. Upon each release all repos get the same tag. Alternatively with tools like mr [1] you can for each release keep a .mrconfig somewhere which keeps the commit SHA for each repo (not 100% sure if mr can create such file by itself, but it's not really hard) so that if you do a fresh clone it checks out each repo at the correct commit.
