@@ -76,6 +76,7 @@ Minor Changes:
 * Fixed the response payload type of `PutSubmodelById` in the Asset Administration Shell Repository OpenAPI files: status code `201` now returns a `Submodel` instead of a `Reference`. (https://github.com/admin-shell-io/aas-specs-api/issues/601[#601])
 * Updated the response contract of `PostAllAssetLinksById` in Discovery OpenAPI files by removing status code `404` for `POST /lookup/shells/{aasIdentifier}` to align with create-or-replace semantics. (https://github.com/admin-shell-io/aas-specs-api/issues/595[#595])
 * Updated the response contract of `PostAllAssetLinksById` in Discovery OpenAPI files by removing status code `409` for `POST /lookup/shells/{aasIdentifier}` to align with replace/update behavior on repeated payloads. (https://github.com/admin-shell-io/aas-specs-api/issues/596[#596])
+* Updated the response contract of `GetAllSubmodelDescriptors` in Submodel Registry OpenAPI files by removing status code `404` for `GET /submodel-descriptors`, so an empty collection is consistently represented by `200` with an empty result. (https://github.com/admin-shell-io/aas-specs-api/issues/597[#597])
