 **Metadata-only updates and versioning configuration**: Introduced new query parameter "_meta-history" for PUT updates when versioning policy is set to either "versioned" or "version-update" to configure whether or not the old version is saved as a historical record. "_meta-history = true" is the default. By default, the resource version is incremented, a new version is created, and the old version is saved as a historical record. "_meta-history=false" can be configured so that the resource version is incremented, a new version is created, but the old version is not saved as a historical record. For more information, visit [metadata-only updates and versioning](./fhir/fhir-versioning-policy-and-history-management.md#metadata-only-updates-and-versioning).
 
 **Composite search parameter collation fix**:  Corrected inconsistent collation handling for Token-String composite search parameters.
