MVB Marko Rodriguez recently announced
the release of TinkerPop 2.4, which is a bunch of graph database frameworks, algorithm packages, servers, and more. This release was dubbed "Gremlin Without a Cause," and you can see the logo to go with it below (it's the Gremlin logo dressed like James Dean).
Gremlin, for those who don't know, is a graph database query language similar to Cypher. One of the commenters noted that Gremlin-Scala
was also released recently on GitHub.
