The project is still alive and we're trying to finish our next major version to be able to better support modern protocols and features.

We do monthly updates on the status of the project that we call State of the Bird and they can be found here https://discourse.imfreedom.org/tag/state-of-the-bird.

Remind me (in a millenium or two) when you can finally do XMPP MAM + message carbons. Until then: lol
