## 0.45.0

* Add support for OpenAPI Callbacks:
    * New docs: [OpenAPI Callbacks](https://fastapi.tiangolo.com/advanced/openapi-callbacks/).
    * Refactor generation of `operationId`s to be valid Python names (also valid variables in most languages).
    * Add `default_response_class` parameter to `APIRouter`.
    * Original PR [#722](https://github.com/tiangolo/fastapi/pull/722) by [@booooh](https://github.com/booooh).

        *   Using `functools.wraps` on a function with different signature
        *   Using `functools.partial` with an invalid `tf.function` input
    *   `tf.function` now enforces input parameter names to be valid Python identifiers. Incompatible names are automatically sanitized similarly to existing SavedModel signature behavior.
