So what's new?
The most important news is the new engine to manage Relationships. We knew the biggest OrientDB's bottleneck was on management of vertices with many edges. Andrey posted a benchmark about importing Wikipedia dataset comparing the new OrientDB 1.7-rc1 and previous OrientDB 1.6.4. In all the tests the new version outperforms the previous one, even 15x! No more pain on managing many edges!
