- BPO 35766, typed_ast is merged back to CPython
- BPO 35813, multiprocessing can now use shared memory segments to avoid pickling costs between processes
- (Hey, fellow core developer, if a feature you find important is missing from this list, let Łukasz know.)

Adrian (voice over): We interrupt this programme to annoy you and make things generally irritating for you.
Cut back to Mr Orbiter-5.
Mr Orbiter: ... with a large piece of wet paper. Turn the paper over - turn the paper over keeping your eye on the camel, and paste down the edge of the sailor's uniform, until the word 'Maudling' is almost totally obscured. Well, that's one way of doing it.
Cut to the BBC world symbol again.
Adrian (voice over): Good evening, we interrupt this programme again, a) to irritate you and, b) to provide work for one of our announcers.
Jack (voice over): Good evening, I'm the announcer who's just been given this job by the BBC and I'd just like to say how grateful I am to the BBC for providing me with work, particularly at this time of year, when things are a bit thin for us announcers...
