The future of FHIR: R4B and R5?
summary
R4B is a technical correction to R4 that fixes invariants, schematics and infrastructure; it includes a potentially breaking MedicationDefinition breaking change that few implementers used so impact is expected to be small. R4B backports subscription changes and adds DescriptionTopic and space-medicine resources, while content negotiation means servers must advertise 4.3. R5 opens for ballot with no new normative content (Patient/Observation edits are STU-only), new resources like ConditionDefinition and Transport, and transforms from R4 arrive after ballot; timelines target releases every ~2 years.
