I like the idea of doing automatic release snapshots / candidates, but I 
think that's a bit too aggressive for actual releases at this point, at 
least on the stable branch. E.g. the recent 32-bit ABI breakage on the 
1.20 branch would likely have made it into a 1.20.y release with this

And then 1_21_*_* as of 21.x.y? Either way, sounds good.
