v2.3 [May 5, 2015]
Neo4j 2.3.1 is a maintenance release, with critical improvements.
Highlights
- exists() can accept maps, enabling IS NOT NULL to work with LOAD CSV
- New PowerShell scripts for common Neo4j tasks
- Faster transition from electing master to becoming master, reducing observed windows of cluster being temporarily without master.
- Fixes a race condition where voting would fail if there was a concurrent role switch happening.
v2.1 [Apr 21, 2014]
- Corrects a Cypher compiler error introduced only in Neo4j 2.1.4, which caused Cypher queries containing nested maps to fail type checking.
- Resolves a critical error, where discrete remove add operations on properties could result in a new property being added, without the old property being correctly removed.
- Corrects an issue causing significantly degraded write performance in larger transactions.
- Improves memory use in Cypher queries containing OPTIONAL MATCH.
- Resolves an issue causing failed index lookups for some newly created integer properties.
- Adds additional metadata (label and ID) to node and relationship representations in JSON responses from the REST API.
- Resolves an issue with extraneous remove commands being added to the legacy auto-index transaction log.
