* Add docs for [Schema Extra - Example](https://fastapi.tiangolo.com/tutorial/schema-extra-example/). PR [#1185](https://github.com/tiangolo/fastapi/pull/1185).

## 0.53.1

* Fix included example after translations refactor. PR [#1182](https://github.com/tiangolo/fastapi/pull/1182).

* `tf.nest` and `tf.data` now support user defined classes implementing `__tf_flatten__` and `__tf_unflatten__` methods. See [nest_util code examples](https://github.com/tensorflow/tensorflow/blob/04869b4e63bfc03cb13627b3e1b879fdd0f69e34/tensorflow/python/util/nest_util.py#L97)
for an example.

*  TensorFlow IO support is now available for Apple Silicon packages.

*  Refactor CpuExecutable to propagate LLVM errors.
