Neo4j Aura Database March Release

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

🚀 Updates

New organizations created after 4 March default to Cypher 25. If you're an Organization admin, you can toggle the setting as needed.
Vector search with filters (in-index filtering) and the new Cypher
SEARCH
syntax for vector queries are now GA and supported for production use.
GRAPH TYPE
is now available in Preview - It provides you the ability to declare your data model in a single, unified blueprint. This enforces strict data integrity including validation of relationship connections and label definitions without sacrificing the flexibility of an open schema.
Added GQL-compliant aliases for existing Cypher functions.
Added
ai.text.structuredOutput()
function to the GenAI Plugin, taking a textual prompt and map schema and outputting the result as a map adhering to the given schema.

🐞 Bug fixes

Fixed a bug in pipelined runtime where sometimes queries with multiple
SelectOrSemiApply
operators in the query plan could fail.
Fixed a bug where use of a composite property index in combination with a dynamic node label or dynamic relationship type could result in an incorrect
MATCH
result being returned.
Fixed issue with conditional query
WHEN
not aggregating null values correctly without a grouping key.
Fixed a bug with the new MergeUniqueNode operator.
