FHIR4: what's new?
summary
Release 4 makes the core infrastructure normative core frozen — data types, formats, REST API and key conformance artifacts (CodeSystem, ValueSet, ConceptMap, StructureDefinition) are locked while the rest stays trial-use; Patient and Observation ballot decisions determine final scope. Version management adds a fhirVersion media type and a $versions operation plus a “managing multiple FHIR versions” page, diffs and conversion scripts. Draft features include Smart App Launch, GraphQL support, and Bulk Data (NDJSON, async jobs, cert-based auth). JSON primitive extension handling remains an open decision.
