Release Note for Neo4j 2025.08

Added allReduce() function to Cypher 25. The allReduce() function is a boolean expression designed to optimize variable path expansion in queries. When used in combination with QPPs, allReduce() allows for early pruning of paths that do not satisfy a predicate specified on a value accumulated over the path. Previously, only conditions based on values available at the current iteration of QPPs could be early-pruned.
Some queries previously unsupported by the NEXT statement are now supported. Queries fragments containing aggregations, updating queries, and DISTINCT used in the context of UNION, after USE, or wrapped in braces, can now follow the NEXT keyword.

Improved the performance of queries that use dynamic labels, making them significantly faster. The planner can use the new DynamicLabelNodeLookup to bring the performance of dynamic label lookups close to that of queries with static label (or relationships type) lookups.

Server
- Fixes a bug when performing comparison operations on point and duration types (and array variants of these) when using a range index, where queries in the form `x >= y` did not find any match when `x == y`. This fix ensures that comparison operations for these types now behave the same when using a range index as when not using an index.
Cypher
- Fixed a bug that caused large numbers to overflow during arithmetic operations with multiple operands. The system will now correctly detect these overflows at runtime, ensuring reliable calculations.
- Fixed an issue where point.distance() and point.withinBBox() queries could fail to find points that were located just outside a restricted spatial index region, even if they were within the search radius. This ensures that queries against a point index with a region now return consistent and accurate results. Note: In some cases, you may need to rebuild your point index for this fix to take full effect.

Fixed a bug that caused an error when creating multiple linked users with a parameterized username. Previously, if you used the same plan to create more than one user, a constraint violation would occur because the unique identifier was being reused. The system now correctly generates a unique identifier for each user, allowing you to create multiple users successfully.
