Here is the current status of v3 onion control port support:

This proposal is listed as "Finished":
https://gitweb.torproject.org/torspec.git/tree/proposals/284-hsv3-control-port.txt

And the code was merged into 0.3.3 (not 0.3.2):
https://trac.torproject.org/projects/tor/ticket/20699

Stem typically tracks Tor's control spec.
But the changed commands have not been integrated into control-spec.txt:
https://trac.torproject.org/projects/tor/ticket/24847

And as a related issue, there is currently no way to ask Tor if it supports
v3 onion control port events:
https://trac.torproject.org/projects/tor/ticket/24617
(But "try it and see" probably works.)
