I don't like blowing my own horn but I feel commit 3311ea86ed "Introduce 
a non-recursive JSON parser" should be in the release notes. This isn't 
something that's purely internal, but it could be used by an extension 
or a client program to parse JSON documents that are too large to handle 
with the existing API.

Maybe "Introduce an incremental JSON parser" would have been a better 
headline.


cheers
