Neo4j Aura Database February 2025 Release Update

The Neo4j Aura February release has started to roll out, commencing on AuraDB Free and progressing to higher tiers later.

Some highlights include:

dbms.components() will return ‘5.27-aura’ in the column versions to maintain compatibility with existing client applications.
Optimized memory consumption for eagerness analysis in Cypher when handling unions.
Status descriptions for notifications now include the database name for unrecognized labels (01N50), relationship types (01N51), and properties (01N52).
NotSystemDatabaseException is now split into two exceptions:
NotSystemDatabaseException
, which is thrown when system-only queries are run on a non-system database, and
DisallowedOnSystemException
, which is thrown when non-system queries are run on the system database.

Fixes

Server: Resolved an issue with populating multiple index types on the same schema from concurrent transactions.
Cypher: Fixed java.lang.NoSuchFieldError: v0_tokenManager error when returning full nodes or relationships in some queries.

Please refer to the Aura Release Notes for more information on any of the changes.
