Neo4j Aura Database January Release Update!

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

This release focused on security patches and improvements in Cypher.

🛡️ Security fixes

We have patched the following libraries to resolve vulnerabilities:

🐞 Cypher Bug fixes

Improved Memory Tracking
: Fixed an issue where
DISTINCT
operations could underestimate heap usage. This ensures that queries exceeding memory pool limits return a recoverable error rather than triggering a JVM
OutOfMemoryError
.
Parallel Runtime Optimization
: Resolved a bug where failed queries in the parallel runtime held onto heap memory longer than necessary.
Subquery Fix
: Fixed a "slot configuration" error when using subquery expressions in
allReduce()
initializers.
Entity Mapping
: Fixed a bug where entities returned inside a map or list were incorrectly evaluated due to a missing eager operator.
