Release Note for Neo4j 5.26.28 (2 July 2026)
Server
- In neo4j admin import: Allow importing from parquet files containing row groups of size 0.
- In neo4j admin import: Fixed an issue where multiple –nodes or –relationships arguments with explicit headers caused them to incorrectly share the first header file. The import process now properly scopes provided header files to each individual file group.
- Fixed an issue where network chunks on secondary nodes failed to flush correctly, resulting in buffer overflows.
Cypher
- Fixed a bug where the parallel runtime returned incorrect data when queries used the {.*} shortcut to return all node properties as a map, e.g MATCH (n) RETURN n {.*} AS map.
Security
- Upgraded Apache Shiro to version 2.2.1 in order to resolve CVE-2026-49268
