• Shift to new version convention in profiles and IGuide to align to the rest of the specification material
• Introduction of narrative describing the current evolutions that IPS-UV is undergoing for their own terminology and slice modeling approach in the next IPS release.
• After extensive testing, this specification has shifted slicing from being applied on CodeableConcept to being applied on Coding. This was done in order to eliminate the risk of validation errors that arise under the previous slicing model.
• Removed redundant profiling (e.g., claiming the base cardinality) on the new coding slices
• Changed Allergy.onset(x) and Condition.onset(x) rules from "closed" to "open" given the evidence from implementers for the need to supply for string and potentially other data types.
• Temporary removal of three GPS slices until modeling is corrected by IPS to ensure validator tools can identify and distinguish use of the value set. Added details on this challenge into Known Issues.
• Updated pointers to CA Baseline and PS-CA packages to align to most recent package updates (1.0.1 and 0.3.0) respectively
• Modification of slices socialized under patient identifier type (removed JPID and PPN, added in MRN)
• Inclusion of PrescribeIT extensions for medication strength and renderedDosageInstruction
• Minor editing corrections (e.g., SNOMED changed to SNOMED CT, removal of spelling error in element description, modified CVC value set descriptions for easier differentiation between download and view links)
