+* **Legacy workflow REST API endpoints have been removed**. All paths under `/api/v1/workflow`
+  are no longer available. Use `/api/v1/bom/token/{uuid}` or `/api/v1/event/token/{uuid}` to
+  check whether a given task, such as BOM upload processing, is still ongoing.
+* **Advisory and CSAF REST API endpoints have been removed**. All paths under `/api/v2/advisories`
+  and `/api/v2/csaf` are no longer available. The functionality was removed because its implementation
+  could not be completed in time for the GA release.
+* **Support for importing CycloneDX BOMs in Protobuf format has been removed**. JSON and XML remain
+  the only accepted formats.
