### Fixes

* 🐛 Fix support for strings in OpenAPI status codes: `default`, `1XX`, `2XX`, `3XX`, `4XX`, `5XX`. PR [#5187](https://github.com/tiangolo/fastapi/pull/5187) by [@JarroVGIT](https://github.com/JarroVGIT).

### Docs

    * If the serialization type is 'application/json':
    * If serialization fails, and the original status code was an failure (e.g. 4xx or 5xx), the original status code will be returned.
