The 1.9 release of Neo4j builds upon the previous 1.8 releases and brings extensive improvements in stability and performance. In addition, Neo4j 1.9 Enterprise introduces auto-clustering support, with dramatically simplified configuration and deployment for high demand production use.
Support for auto-clustering in Neo4j Enterprise, which replaces the previous Zookeeper based HA clustering, provides a streamlined deployment process and is much safer and more resilient in failure scenarios.
New neo4j-arbiter tool, which acts as a voting instance in a Neo4j cluster but does not keep a data store or handle transactions.
Correction of several concurrency and performance issues.
Improvements to Online Backup in Neo4j Enterprise, including auto-detection of full vs incremental backup based on existing content at the backup location.
Updates to Neo4j server webadmin, including welcome pages for new users.
It is recommended to upgrade all previous Neo4j installations to this release. Neo4j 1.9 does not require any explicit upgrade to persistent stores created using Neo4j 1.7 and 1.8 installations, however current users of Neo4j Enterprise must consult the documentation and update the cluster configuration. Please see the deployment and cluster upgrade sections of the Neo4j manual for more detail. Also note that Neo4j 1.9 is tested and supported with Oracle JRE 7. Users of previous Java versions should upgrade to Oracle JRE 7 when deploying Neo4j 1.9.
As part of the Neo4j 1.9 release, 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.

Neo4j 1.8.0 stable release
The 1.8 release of Neo4j provides extensive improvements in stability and performance. As an incremental service release, Neo4j 1.8 builds upon the previous 1.6 and 1.7 releases and provides full backward compatibility.
This release includes the following corrections and improvements:
Correction of several concurrency issues affecting performance in multi-
threaded configurations.
Correction of several concurrency issues that infrequently affect consistency of persisted data.
Optimization of high-availability (HA) protocols to increase write performance.
Support for zero-downtime rolling upgrades in HA clusters.
Improvements to transaction distribution in HA clusters, providing greater resistance to branching.
Configurable rotation of logical logs.
Support for streamed responses to REST API requests.
Support for bi-directional traversals, branch state and path expanders in the traversal framework.
Performance improvements to several graph algorithms.
Support in the Cypher language for writing graph data and updating auto-indexes (manual indexes are not supported).
Extensions to the Cypher language to allow the use of patterns as expressions and predicates.
Correction of several issues in the Cypher parser when using collections and when aggregating.
Improved error reporting in Cypher and more reliable statement parsing.
Support for explicit transactions in neo4j-shell.
It is recommended to upgrade all previous Neo4j installations to this release. Neo4j 1.8 does not require any explicit upgrade to persistent stores created using Neo4j 1.6 and 1.7 installations. Please see the deployment section of the Neo4j manual for more detail.
