From Peter Neubauer’s blog entry:
The Neo4j graph database release 1.1 has just arrived, so here’s some information on the new things that have been included. The main points are the additions of monitoring support, an event framework and a new traversal framework to the kernel. Then two useful components have been added to the default distribution (called “Apoc”): graph algorithms and online backup.
Peter’s post has pointers to other Neo4j resources.
