 Changing the versioning policy either at a system level or resource level won't remove the existing history for any resources in your FHIR service. If you're looking to reduce the history data size in your FHIR service, you must use the [$purge-history](purge-history.md) operation.

+**Import operation honors ingestion of non-sequential resource versions**
+
+Prior to this change incremental mode in import operation assumed versions to be sequential integers. After this bug fix, versions can be ingested in non-sequential order.
