For the next version, work is already started on the HEAD CVS branch, which will add some new killer additions, such as the XML queries (done by Gerhard Dieringer) and lots of new features based on them (import/export of data between unrelated databases, etc).
FOAF updates: Trust rankings are now exported, making the data available to other users and websites. An external FOAF URI has been added, allowing users to link to an additional FOAF file.
