Hi hefee,
we've released stem 1.8.1 [1] including v3 onion services patches [2]. There'd be a pypi package soon (in aprox. 1 day) and stem's website update.
Please, let us know whether that works for you,
Thanks a lot. It looks fine for our use case. And good that you now communicate it openly that there is active development for the moment.
Regards,
hefee
