## 4.33.0

**`(feat):`** Add the `legacy-input-stream-upload-overloads` option (default `false`). When `true`, single-file
upload endpoints get the `InputStream` overloads from before 4.23.2, such as
`create(InputStream stream, String filename)`. These leave out the request object, so companion
multipart fields are not sent, as before 4.23.2.
