The development for the current Xubuntu release is tracked in the Xubuntu work items tracker. In addition to showing the current status for blueprints and their individual work items, including bugs, the tracker displays some general data on progress. Finally, you can access the team calendar and join the development IRC channel #xubuntu-devel within it.
In addition to the work items tracker, the Xubuntu team uses the Xubuntu wiki to organize work on certain projects.
The main communication channels for Xubuntu development are the IRC channel #xubuntu-devel on the Freenode IRC network and the Xubuntu-devel mailing list. The Xubuntu team also runs community meetings more or less regularly.
To see the meeting agenda for the next meeting, refer to the Xubuntu meetings wikipage. Also see the Contact page in the Xubuntu wiki for the list of current leaders and other developer-related contact information.
The Xubuntu contributor documentation is a compilation of guides that help keep the project in the right general direction and describes the processes the community use. Finally, the last part of the documentation instructs contributors to perform certain tasks.
