4.0.0

September 14, 2025

What’s New

  • The connector is now fully compatible with modern Neo4j versions (4.4 and later) and the latest Mule runtime engines (4.9.0 and later), leveraging the updated Neo4j Java driver.

  • The connector simplifies configuration to only require a BOLT URL, as all metadata operations use native Cypher queries through a BOLT connection. The REST URL parameter is now removed.

  • The connector offers improved metadata resolution for a smoother experience in Anypoint Studio, providing access to new features such as reactive APIs, multi-database support, and enhanced security.

  • The connector no longer supports Neo4j 3.x servers, Mule runtime versions earlier than 4.9.0, or JDK versions earlier than 17.
