December 2025: Documentation enhancements in the neo4j/docs-status-codes repository focused on authorization rule error handling. Delivered new error codes 42NAD and 42NAE to clarify issues around non-existent and duplicate authorization rules, improving developer guidance and error management.

Month: 2025-04 — Delivered PBAC (Property-Based Access Control) documentation for relationships in Neo4j Enterprise Edition within the neo4j/docs-cypher repository.

The PBAC content was integrated into the Deprecations, additions, and compatibility page to ensure stakeholders have a consolidated view of changes affecting security and access control.

February 2025 monthly summary for neo4j/docs-cypher: Delivered a documentation update clarifying REVOKE error semantics. The change states REVOKE raises errors for non-existent users, roles, or databases instead of notifying, improving accuracy and reducing user confusion. The change was recorded in the additions/removals section (commit 953c9d0e3f325ca158748baa17d30f6293b6ed33).

In Oct 2024, delivered a Documentation Enhancement for neo4j/docs-operations introducing a property-based access control example in Cypher with temporal logic. The update demonstrates granting read permissions when a node's createdAt is later than the current date, clarifies date() behavior in access control rules, and shows revocation of such privileges. This work improves guidance for security modeling, aligns docs with governance requirements, and reduces ambiguity in permission configurations.
