  • Resolves a uncommon race condition, that could result in errors during database recovery.
  • Correct an issue that could result in leaks of file descriptors.
  • Resolves an issue preventing online backups (Neo4j Enterprise) after upgrading from Neo4j 1.9.
  • Ensure REST responses use https locations when requested.
  • Remove need to specify single:// when running neo4j-backup, and deprecates the use of the ha:// modifier.
  • Support for the ‘UNWIND’ clause in Cypher.
