Google End-to-End: Any update?

It's been a year since Google posted this update[1] on their end-to-end project and a month since the last commit.[2]

Yahoo announced a forked end-to-end extension in March[3] and while commits have been more frequent[4], they haven't released either.

Does anyone have any update on these?
