* Fix ZeroMQSocketListener and ZeroMQSocketHandler examples
* Use send_json and recv_json to simplify pyzmq interfacing
* Add News entry
(cherry picked from commit 586c0502b5)
CPython workflow is changing! We're going to start using "blurb"
to manage Misc/NEWS entries:
https://github.com/python/core-workflow
(This will be a big win for release managers, honest.)
This checkin simply populates the "Misc/NEWS.d" subdirectory tree
so that people can start putting their news entries in there.
No other changes (yet).
