Release Notes: Neo4j Aura Database – Feb 2025

Release Date: 26 February 2025

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

Release Note for Aura DB 2025.02 (26 February 2025)

Neo4j Server

• dbms.components() will return ‘5.27-aura’ in the column versions. This is to support existing client applications that rely on the previous version format.

Surface for Developers and Data Scientists

• Reduces the memory consumption of eagerness analysis in Cypher in the presence of unions. 
• The status description for notifications now additionally includes the name of the database for unrecognized labels (01N50), relationship types (01N51) and properties (01N52). 
• Current NotSystemDatabaseException is split into NotSystemDatabaseException and DisallowedOnSystemException, where the first is thrown when system-only queries are run towards another database and the latter is thrown when non-system queries are run towards the system database. 

Fixes

Server

• Fixes an issue when populating multiple indexes of the different types on the same schema from concurrent transactions

Cypher

• Fix error generated java.lang.NoSuchFieldError: v0_tokenManager for some queries when returning full nodes or relationships. 

Please refer to the changelog for full details of the changes.
