Neo4j Aura Database March SECOND Release

The Neo4j Aura March SECOND release is now rolling out—starting with AuraDB Free and gradually extending to higher-tier instances.

This second release in March reveals excited new security features and Cypher 25 updates!

🧑🏻‍💻Cypher 25: New Path Modes & Visibility

We’ve added several features to make your queries safer and more transparent:

ACYCLIC Path Mode
: You can now specify that a node cannot be traversed more than once in a pattern match, avoiding loops.
LOAD CSV Progress Tracking
: Use
SHOW TRANSACTIONS
to see real-time progress metrics for ingestion jobs.
GQL Conformance
: We’ve added the
PROPERTY_EXISTS()
function to keep your code aligned with the latest GQL standards.

🚛 Fleet Manager Updates

These apply if you are running Self-managed Neo4j instances, and upgraded the Neo4j version of your instances to 2026.03:

Built-in Fleet Manager
: You won't need a plug-in to use Fleet Manager to manage your Self-managed Neo4j instances on Aura console anymore. It is ready by default.
Query Log Aggregation
: You can now view aggregate query logs directly in the Aura console. Ensure
db.logs.query.obfuscate_literals=true
is set to enable this.

🛠️ Bug and Security Fixes

Updated Jetty to v12.0.33 to resolve CVE-2026-1605.
Fixed a rare bug in the pipelined runtime involving EXISTS subqueries that could cause incorrect intermediate results.
Dynamic lookups now use locking index seeks when required, whereas previously they were vulnerable to constraint violations if used concurrently in a merge context.
