FHIR release R4B over R4

[nazrulworld]

From fhir.resources v6.5.0

FHIR release R4B is coming with not that much changes over the release of R4. So we decided not to create separate sub-package for R4 like STU3, instead there just overlaps on existing R4. This also means that in future, when we will work on R5; there will be sub-package for R4B and no R4.
We suggest you to try make a plan to be upgraded to R4B. Here you could find related information dealing-strategy-R4-R4B
