Cheers, Michael > Neo4j 2.1.7 is a maintenance release, with critical improvements. > > Notably, this release: > > Default configuration for the relationship group store memory mapping > (neostore.relationshipgroupstore.db.mapped_memory) is now 10M rather than 0, > which provides a significant performance improvement. > Resolves an issue where excessive memory could be used during recovery after > an unexpected shutdown. > Improves the enforcement of schema constraints, resolving several rare race > conditions. > Ensure the batch importer correctly enforces schema constraints. > Improvements to error checking for some Cypher queries using shortestPath. > Performance improvements in the serialization of responses to REST API > requests. > Resolves an issue that could cause backups to be un-usable in slave instances > of a HA cluster (Neo4j Enterprise). > Improvements to HA cluster error handling (Neo4j Enterprise). > All Neo4j 2.x users are recommended to upgrade to this release. Upgrading to > Neo4j 2.1, from Neo4j 1.9.x or Neo4j 2.0.x, requires a migration to the > on-disk store <http://neo4j.com/docs/2.1.7/deployment-upgrading.html> and can > not be reversed. Please ensure you have a valid backup before proceeding, > then use on a test or staging server to understand any changed behaviors > before going into production. > > Neo4j 1.9 users may upgrade directly to this release, and are recommended to > do so carefully. We strongly encourage verifying the syntax and validating > all responses from your Cypher scripts, REST calls, and Java code before > upgrading any production system.
