*   Added experimental support for parallel batching to `batch()` and
        `padded_batch()`. This functionality can be enabled through
        `tf.data.Options()`.
    *   Support cancellation of long-running `reduce`.
    *   Now we use `dataset` node name as prefix instead of the op name, to
        identify the component correctly in metrics, for pipelines with repeated
        components.

* 📝 Update docs for responses and new stream with `yield`. PR [#15023](https://github.com/fastapi/fastapi/pull/15023) by [@tiangolo](https://github.com/tiangolo).
* 📝 Add `await` in `StreamingResponse` code example to allow cancellation. PR [#14681](https://github.com/fastapi/fastapi/pull/14681) by [@casperdcl](https://github.com/casperdcl).
