Release Date: 7 November 2022
Neo4j 4.4.13 is a maintenance release with many important improvements and fixes.

Kernel

  • Fix a bug where a failure in transaction event listener could cause faulty reuse of internal transaction object. Observed symptom is failing to open a new transaction due to what looks like a memory leak.
  • Fix edge case where active transactions metrics were inconsistently decremented on closing a transaction, which lead to <prefix>.transaction.active_read to potentially appear negative.
  • Bump commons-text 1.9 -> 1.10.0 so as to address CVE-2022-42889
  • Fixes possible crashes when using very small page cache sizes
  • Upgraded Lucene to version 8.11.2 to pick up security fixes

Cypher

  • Fix a bug where SHOW DATABASES may not include all servers for a database if the servers have the same value for server.bolt.advertised_address
  • Fix a bug in pipelined runtime that can cause incorrect row ordering in queries that leverage order and contain an aggregation.
  • Fix bug where columns could be swapped for UNION queries.
  • Upgraded Apache Shiro from 1.9.1 to 1.10.0
  • Fix bitIndex < 0 errors during physical planning of complex queries with dynamic scheduling, like ordered union.
  • Fix bug in Expand(Into) where we could fail to find existing relationships if the same node is expanded multiple times.

Clustering

  • Fix bug where store copy failed to retry against certain remotes due to issues with address locking logic.
  • Bug fix where the wrong artefact was chosen for databases with the same name but different database ids.
