### Features

* ✨ Add support for streaming JSON Lines and binary data with `yield`. PR [#15022](https://github.com/fastapi/fastapi/pull/15022) by [@tiangolo](https://github.com/tiangolo).
    * This also upgrades Starlette from `>=0.40.0` to `>=0.46.0`, as it's needed to properly unrwap and re-raise exceptions from exception groups.
    * New docs: [Stream JSON Lines](https://fastapi.tiangolo.com/tutorial/stream-json-lines/).
