Taming the Evolution of Cypher: What Cypher Versions Mean for You
summary
Neo4j 2025.06 decouples language from server so a single DBMS can host multiple Cypher versions—Cypher 5 frozen LTS and Cypher 25 monthly releases. Cypher 5 receives only security and planner/runtime performance patches; Cypher 25 delivers new features (vector type, conditional expressions, new next keyword, trigonometric and temporal format/parse functions, or/reduce) with breaking changes only at release boundaries. Databases carry a default Cypher version, queries can be prefixed with cypher 25, defaults can be altered and availability is visible via SHOW DATABASE / CALL DBMS.components.
