Neo4j 1.9.M03 has been released and an official bulletin have been posted on their blog
Changes and improvements includes:
We removed an issue with relationship-type-id’s which allows everyone to use the full size of 16 bit aka 65535 different relationship-types now. We also worked on the Java7/OpenJDK support (so far compilation and tests).
For the new HA mode we improved the logging, added more tests and made it more robust on startup and when clients leave the cluster in order to stabilize the component for Neo4j 1.9.GA.
In this milestone, the code for the Tinkerpop integration into the Neo4j Server and its Web-Interface and the Gremlin Plugin has been refactored and centralized. This makes all Tinkerpop dependencies reside only inside that plugin. So it will be possible to support two versions of the Gremlin plugin, one for the 1.5 release and another plugin for the current 2.2.
Cypher got a lot of internal refactoring, especially around the internal handling of start- and updating clauses and general parse-result representation and management.
Our Cypher code has seen some bug fixes, namely around queries that returned non-existant pathshttps://github.com/neo4j/neo4j/issues/336, substring length limitshttps://github.com/neo4j/neo4j/issues/369 and updating properties in bulk with SET. We also removed the now obsolete Cypher Plugin that has been deprecated for two releases now.
