Release Notes: Neo4j 4.2.19

Release Date: 11 August 2022

Neo4j 4.2.19 is a maintenance release with many important improvements and fixes. Neo4j 4.2 has reached End of Life.

Cypher

• Adds blocklist of ip addresses for cypher’s outbound http requests

Packaging

• Changed neo4j.service behaviour to stop neo4j getting stuck in an endless restart loop when neo4j consistently errors on startup (for example if the neo4j.conf is misconfigured).

Browser

• Modernize background queries & remove use of deprectated syntax

• Always send transaction metadata on cypher queries

• Read cluster role from SHOW DATABASES rather than deprecated dbms.cluster.role

• Make sure proper metadata is passed along with queries

• Handle upcoming setting renames in neo4j 5.0

• Fix PNG exports font

• Use SHOW TRANSACTIONS instead of dbms.listQueries in :queries

• Re-add metrics for successful queries

• (*) in property panel now shows node count, rather than total label count

• Add url param to preselect in connect frame

Docker

• Redhat are no longer supporting or updating the openjdk docker images that we use as base images. This means there will no longer be security updates to openjdk images after July 2022.

  • https://github.com/docker-library/openjdk/issues/505

  • https://github.com/docker-library/docs/pull/2162

  Switching Docker base image to eclipse-temurin AdoptOpenJDK java built on top of debian:bullseye-slim.

• Change base image to eclipse temurin JRE not JDK. The JDK is overkill and could introduce unnecessary security issues.
