v0.7.1 - General performance improvements and bug fixes

C++

• Adds an ErrorReporter to expose encountered profile conversion and validation issues
• Improves FHIRPath handling of Decimal primitives, adds support for FHIRPath substring functions, and includes general FHIRPath performance improvements
• Minor performance improvements and bug fixes to parsing/printing

Bug Fixes

• Ensure FHIR Date/Datetime year is always printed with four digits according to the specification
• Properly resolve X.reference to a string during FHIRPath evaluation
• Fix FHIRPath handling of the union operator
• Fix handling of parsing complex Extensions with singular repeated fields
• Fix FHIR parser race condition present in memoization

Go

• Deprecated proto.MessageV1 APIs are migrated to proto.MessageV2
• Marshalling extension fields to the analytic schema will now fail as conflicting if the field name differs only by case
• Return an error when unmarshalling JSON that contains multiple values for a value[x] field (previously one was silently chosen)

Java

• Eliminate legacy JsonToProto example. For usage, see github.com/google/fhir-examples
• Break //java/com/google/fhir/common into individual targets
• Update ProtoGenerator to dump split resources to a single .zip file
• Add ability to mark code values as deprecated during proto generation
• Remove order-dependence during profile generation

Bug Fixes

• Remove upper-bound check for Decimal to conform to the FHIR specification

Python

• Add support for Python 3.9 interpreters
• Bump rules_python to 0.1.0
• Loosen package dependencies in requirements.txt to allow for alternate patch versions
• Remove DescriptorProto from the annotation_utils API

Bug Fixes
