Development branch of Psi XMPP client by psi-dev@conference.jabber.ru NOTE This is intended for advanced users and developers. NOTE This can coexist with the stable psi package. In 2009 a Psi fork named Psi+ was started. Project purposes are: implementation of new features, writing of patches and plugins for transferring them to upstream. As of 2017 the most of active Psi+ developers have become official Psi developers, but Psi+ still has a number of unique features. From developers point of view Psi+ is just a development branch of Psi IM client which is hosted at separate git repositories and for which rolling release development model is used. NOTE psi-plus currently needs access to the internet to build.
