Today we released the 2.0.2 maintenance release of Neo4j. This release comes with some critical stability improvements as well as a few small but handy Cypher type conversion functions. All Neo4j users are strongly recommended to upgrade to this release.
Head on over to http://www.neo4j.org/download to upgrade to Neo4j 2.0.2.
Neo4j 2.0.2 does not require any store-level upgrades from the previous 2.0.1 release.
Where in the Documentation Can I Learn More about Upgrades?The Upgrade section of the Neo4j documentation can be found here, and also covers upgrades to 2.0.
The upgrade basically happens by starting your Neo4j data store (after making the backup) with Neo4j 2.0 and the configuration
allow_store_upgrade=trueenabled in the configuration file
To avoid running into server startup issues as part of the upgrade, you can also use the neo4j-shell for that purpose. The command line call would then be:
bin/neo4j-shell -path data/graph.db -config conf/neo4j.properties.
