Release Date: 28 August 2026
The Neo4j Aura August release has started to roll out, commencing on AuraDB Free and progressing to higher tiers later.Release Note for Neo4j 2026.08
Cypher 25 Features
- Introduces the new UUID type alongside new constructor functions uuid(), uuid(name :: STRING) and uuid(mostSigBits :: INTEGER, leastSigBits :: INTEGER) as well as helper functions; uuid.leastSignificantBits(uuid :: UUID) and uuid.mostSignificantBits(uuid :: UUID).
- Introduction of string interpolation, a STRING literal syntax (s”…” or S”…”) that embeds expressions enclosed in {} directly within a string. See the Cypher Manual -> String interpolation.
- Introduces SHOW USERS AS COMMANDS and SHOW ROLES AS COMMANDS, to get a create role/user or grant role to user/auth rule command string that can be executed to recreate the current setup of roles, users and their assignments. See Operations Manual -> Manage roles and Manage users.
- Allows PBAC rules to have predicates which check for the presence of a value in a list property e.g. GRANT … FOR (n) WHERE ‘gold’ IN n.clearanceLevels TO role. This also allows other predicates to have the property on the right-hand side. e.g. GRANT … FOR (n) WHERE 1 > n.level TO role.See Operations Manual -> Property-based access control.
- LIMIT/SKIP INTEGER as well as LOAD CSV’s FIELDTERMINATOR STRING no longer considered sensitive for logging purposes (I.e they will now show up unobfuscated in query log)
Bug fixes
Cypher 25
- Fix null / 0 raising a division-by-zero error instead of returning null as per the GQL specification and the documented behaviour.
- Fixes a bug in Composite where subquery dependencies were mistakenly propagated to all WITH clauses. For aggregating WITH clauses, this incorrectly altered the set of grouping keys.
- Fixes an issue where a lone USE was inside a COUNT/EXISTS subquery expression
- Fix bug where dynamic property targets could observe earlier assignments in the same SET clause: CREATE (:A {x: 0, y: 1}); MATCH (n:A) SET n[‘x’] = n.y, n[‘y’] = n.x; MATCH (n:A) RETURN n.x AS x, n.y AS y; now correctly returns x=1, y=0 as in 2026.05.0 and before, instead of x=1, y=1.
