Neo4j 2.1 has been released, bringing improvements to the user experience and under-the-hood enhancements, including easy import with ETL features directly in Cypher, optimized for graphs of millions of scale. The new LOAD CSV clause allows users to easily extract data from legacy databases and bring it into Neo4j to experience its true graph form. Additionally, Neo4j 2.1 introduces dense nodes support, which provides a transparent performance boost when accessing relatively fewer relationships amongst the general mass of relationships in social graphs. New Cypher functionality includes the UNWIND function and an experimental query planner that improves performance for some queries. Other notable improvements include a new lock manager in Neo4j Enterprise Edition and official support for OpenJDK 7.
