Release Date: 11/30/2017

Neo4j 3.3.1 is a maintenance release with many important improvements and fixes.


  • Make the dbms.checkpoint.iops.limit setting dynamic so it can be changed at runtime with the dbms.setConfigValue(setting, value) procedure. #10313
  • Add --pagecache parameter to the neo4j-admin backup command, with a default value of 8 MiB that now overrides the page cache setting in neo4j.conf. #10463
  • Fixes #10353 so that calling exists or IS NOT null on a property of a null node evaluates to null #10371
  • Equality for lists is now in accordance with OpenCypher. #10411
    • Before this change, [1,2,3] = [1,2,null] returned false. Now, this comparison will return null which makes equality more consistent in it’s behavior.
