Michele Giorgio Bellizzi enhanced the PN-stream API documentation for the pagopa/pn-stream repository, focusing on the v2.6 release. He introduced new event types, such as ANALOG_WORKFLOW_RECIPIENT_DECEASED and RETURNED_TO_SENDER, and clarified the usage of waitForAccepted across different stream types. Working primarily with YAML and leveraging his skills in API design and documentation, Michele updated internal FAQ links to reflect the latest guidance. His work improved developer onboarding and reduced integration ambiguity by aligning documentation with recent changes, demonstrating careful attention to release-note discipline and effective cross-team collaboration to support partner adoption and reduce support overhead.
