Release 3.8.0

[Jammjammjamm]

3.8.0

• Update the validator service to version 2.3.0 based on version 6.0.21 of the
  FHIR validation code (FI-1995: Changes for HL7 validator v6.0.21 #449).
• Minor visual updates.
• Update the version of the SMART App Launch Test Kit (FI-2031: Integrate SMART App Launch Test Kit update #451). This update will
  add some additional inputs for app launch tests when using SMART App Launch
  2.0.0. These inputs are locked, so no change in behavior is needed when
  running the tests from the UI. If using the JSON API to run tests, however,
  the following new inputs will need to be included in the API calls to create a
  test run:

{
  "name": "client_auth_type",
  "value": "confidential_symmetric",
},
{
  "name": "client_auth_encryption_method",
  "value": "ES384",
},
{
  "name": "public_client_auth_type",
  "value": "public",
},
