Multiple Choice

New versions of FHIR will be published on a release cycle approximately how long?

New versions of FHIR are published on a roughly 18 to 24 month release cycle. This cadence gives enough time for designing changes, gathering implementer feedback, and updating tooling and tests, while still delivering useful progress at a regular pace. A year-long cycle would rush changes, increasing the risk of incompatibilities and costly migrations for systems that implement FHIR. A cycle as long as 30–36 months would slow interoperability improvements and make planning upgrades harder for providers and vendors. The 18–24 month window balances progress with stability, aligning with how FHIR evolves over successive major releases.
