Indeed, and you're right to point it. I strongly suggest you submit a 
ticket to the doc maintainers.

Well, here again, it sure would help to make clear that peps (and 
release specific "what's new") *are* part of the doc. But for sure, what 
used to be a simple and clear reference is now a bit of a mess, despite 
the hard work of the doc team. Side-effect of the rapid growth of the 
language I guess...
