Release Date: 25 November 2022
Neo4j 4.4.15 is a maintenance release with many important improvements and fixes.

Kernel

  • Upgraded jettison to 1.5.1 to mitigate CVE-2022-40150 and CVE-2022-40149

Cypher

  • We were not able to plan value hash joins when the properties are wrapped in a function call. This has been fixed now.
  • Previously, the planner did not assume an expression like n.prop =~ ... to filter the results more than just the bare existence of n.prop. This was changed, such that the planner would prefer to apply these predicates earlier during the query evaluation.
  • Fixed a bug where an updating query might get stuck in an infinite loop during planning.
  • Fix error Exception closing multiple resources that could happen for plans using Expand(Into), see Github issue: https://github.com/neo4j/neo4j/issues/12968
