Release Note for Neo4j 2025.10.1 (Release date: 28 October 2025)

Cypher

Cypher 25 additive features

  • Introduced VECTOR as a new type supported by Cypher, Block store format, and v6 drivers.
  • The previous release introduced the ability to format temporal values as strings. In this release, we tackle the other side of the temporals/strings mapping by allowing the construction of temporal values from formatted strings. Temporal value constructors have been extended to take an optional pattern parameter that describes the structure of the incoming temporal string representation.  

Cypher errors improvements

  • To assist with error identification, query logs in JSON format and cypher-shell now display the query string along with the position marker of where an error occurred. This enhancement is part of the new error framework.

Bug fixes

Cypher

  • Allow using null as default procedure parameter value for all non-primitive types. 
  • Fixes a bug where the values in the options maps of CREATE INDEX and CONSTRAINTS commands could become transposed. 

Server

  • Fixes a rare issue where malformed tokens (empty string or containing null bytes) could bypass validation and cause database panic
  • Avoid stack overflow when sorting free IDs for big value store 

Please refer to the changelog for full details of the changes, and Neo4j Release notes for all changes to other Neo4j products and services.
