Today, we're releasing Neo4j 1.9.M04, a milestone on our way to the Neo4j 1.9 release, which includes improvements in Cypher performance and support for Scala 2.10. The update addresses several issues, including recovery problems and performance concerns with REST-batch-operations. We've also made enhancements to our High Availability Cluster, making it easier to operate and providing a new master information endpoint for HA clusters. As always, we welcome feedback to ensure the stability of Neo4j 1.9.GA.
