Breaking changes

Supported Elasticsearch versions

  • Starting from Snow Owl version 9, Elasticsearch 7.x series support has been marked as deprecated. Maintenance and security fixes will continue to be added to the system, but support will be dropped in the next major release.

API changes

  • Removed deprecated POST /login endpoint in favor of POST /token endpoint (6693bf6)
  • Removed deprecated timestamp query parameter from Bundle, CodeSystem, ValueSet, ConceptMap get by id endpoints (336eba6)
  • Removed deprecated Suggest API parameters (d1f0e33)
  • Removed deprecated codeSystemUri property from generic concept representations (27d45a5)
  • Removed charset=UTF-8 part from JSON and XML media types (#1238)
  • FHIR ConceptMap R4 and R4B representations are currently not supported. It is recommended to migrate the resource to R5 locally and then send it to Snow Owl. (see #1227)

Core

  • New, overhauled Terminology Upgrade and Analysis API (available in paid tiers) (#1193, #1197, #1211, #1237)
    • Replaces the now deprecated and removed CodeSystem Upgrade API
    • Supports upgrade of any kind of terminology resource type to a newer version dependency via content specific analysis, reporting and isolated branch management
  • Terminology Resource Collections (#1196)
    • New resource type and infrastructure that allows bundling and managing multiple resources together
    • The first supported Terminology Resource Collection instance type is SNOMED CT Reference Set Collections (available in paid tiers)
  • Add support for special resource ID suffixes and the tilde (~) path expression (#1228)
    • ~ character is an URL safe character that from now on can be used to denote direct subpaths of a resource (eg. version) or can be used by third party libraries to denote an altered/derived version of a resource that is stored and managed by another index
  • New, index schema migration infrastructure has been added to automatically migrate existing datasets when a mapping change occurs in the system (#1249, #1250, #1251)

FHIR

  • Add missing properties to CapabilityStatement (#1219, #1247)
