Release Date: 11/11/2013

The 1.9.5 release of Neo4j is a maintenance release that addresses several critical issues affecting HA cluster deployment and stability. Notably, this release addresses:

  • Improvement to handling DNS hostnames, rather than IP addresses, in configuration
  • Resolved several issues that could destabilise a HA cluster during failover and master election
  • Improved shutdown of the database to ensure running transactions are given time to complete
  • Improved delivery and processing of status messages within a HA cluster
  • Resolved several concurrency issues in the database kernel, that could result in deadlocks or other failures
  • Various performance improvements to traversals and graph algorithms
All Neo4j users are strongly recommended to upgrade to this release. Neo4j 1.9.5 does not require any store-level upgrades. For a full summary of changes in this release, please review the CHANGES.TXT file contained within the distribution. As part of the Neo4j 1.9 release series, multiple behaviours and features of Neo4j have been declared as deprecated, in order to help users prepare for the removal of these in the next major Neo4j release. A list of deprecations can be found in the Neo4j manual.
