### Breaking changes

For a data source query made via /api/ds/query :

- If the `DatasourceQueryMultiStatus` feature is enabled and
  - The data source response has an error set as part of the `DataResponse`, the resulting HTTP status code is now `207 Multi Status` instead of `400 Bad gateway`
- If the `DatasourceQueryMultiStatus` feature is **not** enabled and
  - The data source response has an error set as part of the `DataResponse`, the resulting HTTP status code is `400 Bad Request` (no breaking change)
