Release 3: Mar 21, 2017. STU3

This is the full FHIR Release 3 (R3). R3 is a complete overhaul of the specification from R2, with over 2400 change proposals process, and applied in R3. Of those changes, 380+ are labelled as a breaking change. Given this level of change, there is no useful way to present a single change list. Users can use the R2/R3 difference comparison, the R2 <-> R3 transforms, or the "Compare to R2" link at the foot of every page to help visualise the differences between R2 and R3.

Many of the changes made in this release (since 1.8.0) are in response to Quality Assurance processes in HL7, with a goal of readying the specification for Normative processes in R4:

Roll up: Of all the many changes (thousands) between R2 and R3, these are the most significant:
