Release Date: 14 October 2021
Neo4j 4.3.6 is a maintenance release with many important improvements and fixes.


  • Fixes a bug in node index seek on a unique property in write queries. For example MATCH (n:Node) WHERE n.unique IN [‘does not exist’, ‘exists’] DELETE DETACH n would fail to delete nodes if there is a unique constraint on unique and at least one predicate does not match any nodes.
  • Fixes an issue where neo4j-admin passed arguments in @ that contained a large amount of arguments (e.g for import)
  • Don’t plan NodeHashJoin for argument variable
