3.0 Tinkerpop Doc - Is graph.close() really implemented?

It used to be in 2.x Tikerpop API, we do shutdown(), but the 3.0 document http://orientdb.com/docs/3.0.x/tinkerpop3/OrientDB-TinkerPop3.html suggest/imply that the new call is close(). But the blueprint still only has shutdown (). Could it be a documentation error?
