### Bug or Regression

- Client-go: fixes potential data races retrying requests using a custom io.Reader body; with this fix, only requests with no body or with string / []byte / runtime.Object bodies can be retried ([#113933](https://github.com/kubernetes/kubernetes/pull/113933), [@liggitt](https://github.com/liggitt)) [SIG API Machinery]

    * And here's the updated documentation for using [`Form` parameters mixed with `File` parameters, supporting `bytes` and `UploadFile`](https://fastapi.tiangolo.com/tutorial/request-forms-and-files/) at the same time.
    * PR [#63](https://github.com/tiangolo/fastapi/pull/63).
