Release Note for Neo4j 2025.07.01 (5 August 2025)

This is a hotfix release

Critical Bug Fix

Fixed Java Driver Connection Issues This hotfix resolves a connectivity regression introduced in version 2025.07.0 that caused Java drivers to hang indefinitely when attempting to connect to the server. What was affected:
  • Java applications using supported drivers experienced connection timeouts and hangs
  • Connections would fail during the initial handshake process
What we fixed:
  • Corrected protocol version negotiation to only offer properly supported versions
  • Restored reliable connectivity for Java drivers
Action required: We recommend upgrading to version 2025.07.1 immediately if you experienced connection issues after upgrading to 2025.07.0, particularly if you’re using Java-based applications. Additional notes:
  • This fix is backward compatible and does not require changes to your application code
Please refer to the changelog for full details of the changes.
