Neo4j Aura August 2026 Release

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

🚀 New Cypher 25 features

Native UUID Support
: Introduced the new
UUID
type alongside new constructor functions (
uuid()
,
uuid(name :: STRING)
,
uuid(mostSigBits :: INTEGER
,
leastSigBits :: INTEGER
)) and helper functions (
uuid.leastSignificantBits()
,
uuid.mostSignificantBits()
).
String Interpolation
: You can now embed expressions directly within strings using the new literal syntax
s"..."
or
S"..."
(enclosing expressions in
{}
).
List Predicates in PBAC
: Property-based access control rules now allow predicates to check for the presence of a value in a list property (e.g.,
GRANT ... FOR (n) WHERE 'gold' IN n.clearanceLevels TO role
). Property values can also now sit on the right-hand side of predicates (e.g.,
WHERE 1 > n.level
).
Clearer Query Logs
:
LIMIT/SKIP INTEGER
and
LOAD CSV
's
FIELDTERMINATOR STRING
are no longer considered sensitive and will show up unobfuscated in query logs.

🛠️ Bug Fixes

Composite Database Subqueries
: Fixed an issue where passing an outside variable into a
CALL
subquery mistakenly injected it into every
WITH
clause as a grouping key. This previously caused query rejections due to fake memory spikes (OOM errors) and returned empty results instead of a correct count of
0
when no data was found.
Dynamic Property Assignment
: Fixed a bug where dynamic property targets could incorrectly observe earlier assignments in the same
SET
clause (e.g.,
SET n['x'] = n.y, n['y'] = n.x
now correctly swaps values instead of duplicating one).
Math Operations
:
null / 0
now correctly returns
null
instead of raising a division-by-zero error, aligning with the GQL specification.
Subqueries
: Fixed an issue where a lone
USE
was placed inside a
COUNT/EXISTS
subquery expression.
