Release 8.1.0

8.1.0 Release (March 2023)

This release has an overhaul of the FHIR API 🔥 and adds support for multiple code systems within the FHIR API!

Previously Snowstorm only supported SNOMED CT but this release adds support for LOINC, ICD-10 (International), ICD-10-CM (US) and
any other code system using a FHIR package or the Custom code system format.

The custom code system format allows any local or national code system to be supported. These need to be transformed into the custom code system format before being loaded.

See Snowstorm FHIR Terminology Server documentation for details of how to load each package format and a link to the updated Postman collection for v8.

Breaking

• Elasticsearch version minimum 7.10.0, maximum 7.17.x, MUST be used (since Snowstorm 8.0.0).
• FHIR API no longer defaults to the SNOMED CT code system, now a system must always be specified. This is in alignment with the FHIR specification.
• Renamed FHIR Elasticsearch indices with fhir_ prefix

Features

• Add FHIR support generic CodeSystems
  • HL7 terminologies and many other code systems supported
  • Import can use 'FHIR package' from simplifier.net
  • Alternatively import can use HAPI custom code system format
• Add FHIR Support for LOINC
  • Import uses LOINC package format
• Add FHIR Support for ICD-10
  • Import uses ICD-10 ClaML format
• Add FHIR Support for ICD-10-CM
  • Import uses ICD-10-CM native format
• Add support for FHIR ValueSets with nesting, for non-SNOMED CT value sets

Improvements

• Improve FHIR code system version resolution
• Include resolved code system version in FHIR responses
• Improved FHIR error catching and reporting
• ISTO-41 Include optional non-SNOMED CT term in ReferenceSetMembers API response
• FRI-491 Improve autoMergedConcept in MergeReviewConceptVersions to be based on sourceConcept with changes from targetConcept re-applied
• FRI-600 Add property to MergeReviewConceptVersions to indicate whether targetConcept is based on an older version of the CodeSystem in relation to sourceConcept
