Neo4j Aura Database June Release Update

The Neo4j Aura June release is now rolling out—starting with AuraDB Free and gradually extending to higher-tier instances.
As previously announced, this release introduces Cypher language versioning. Neo4j now supports two Cypher versions:
Cypher 5 (backwards-compatible and frozen; receives only bug and security fixes)
Cypher 25 (actively evolving with new language features).
Existing and new Aura instances currently default to Cypher 5 — switching to Cypher 25 requires explicit action.
You can set the default Cypher version per Aura instance using the command:
ALTER DATABASE neo4j SET DEFAULT LANGUAGE CYPHER <5/25>
Individual queries can also override the default with the CYPHER <version>
 prefix.
