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 labeled 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:
|
| 1.9.0 |
FHIR Rolling Build, 2016 Dec onwards
|
| 1.8.0 |

Breaking Changes Summary:
These are only the more significant changes, there were many 100s of changes made in response to ballot comments and ongoing implementation experience.
These include breaking changes to may resources. Structural changes are summarized here, and Transforms between DSTU 2 and STU 3
are provided for many resources.

- Change the Navigation menu to focus on indexes to the content in the specification
- Move FHIRPath expression language to its long term home
Technical Changes:
- RESTful API

FHIR Connectathon 12 Snapshot, Mar 30 2016
Frozen base for Connectathon 12 & For Comment ballots:

FHIR API and Serialization Format Enhancement
- The _sort parameter has been reworked
- New or extended search parameters for read, search or history: _type, _at, _summary, _elements
- Change Turtle representation - now ready for trial
-
Conformance resources with significant breaking changes and behavior:

- CodeSystem now separated out from ValueSet: CodeSystem is now a first class resource type in order to support use throughout the FHIR eco-system, such as to support value set expansion and validation. It is intended to be used for distributing the smaller ad-hoc code systems that are ubiquitously encountered throughout the healthcare process.
