I think that you're refering to qTox(which is currebtly not being maintained). Tox, the protocol, continues development as usual.

Really? I guess you guys are active elsewhere and not on the mailing lists, because those are as dead as a very dead thing. :)

Well, I don't know if anyone else responds to the mailing lists anymore to be honest. You can still get in touch through IRC though. We are on libera currently(and dogfooding tox groupchats). #tox for user related questions and #toktok for development.

Edit: Also, development is happening on github: https://github.com/TokTok/c-toxcore
