+## 11.0.2 (2026-11-04)
+### Search parameters
+- Added search parameters `relatedPersonCPRIdentifier` (CPR identifier) and `relatedPersonRelationshipParauth` (relationship code `PARAUTH`) on RelatedPerson, and the uniqueness constraint `relatedPersonCPRIdentifierPatientParauthUnique`: a patient can have at most one RelatedPerson with a given CPR identifier and the relationship code `PARAUTH`. **Note for vendors:** creating a second such RelatedPerson is rejected with HTTP 409 (Conflict).
