 * 🐛 Fix support for `StreamingResponse`s with dependencies with `yield` or `UploadFile`s, close after the response is done. PR [#14099](https://github.com/fastapi/fastapi/pull/14099) by [@tiangolo](https://github.com/tiangolo).
 
+Before FastAPI 0.118.0, if you used a dependency with `yield`, it would run the exit code after the *path operation function* returned but right before sending the response.
+
+This change also meant that if you returned a `StreamingResponse`, the exit code of the dependency with `yield` would have been already run.
+
+For example, if you had a database session in a dependency with `yield`, the `StreamingResponse` would not be able to use that session while streaming data because the session would have already been closed in the exit code after `yield`.
+
+This behavior was reverted in 0.118.0, to make the exit code after `yield` be executed after the response is sent.
+
+You can read more about it in the docs for [Advanced Dependencies - Dependencies with `yield`, `HTTPException`, `except` and Background Tasks](https://fastapi.tiangolo.com/advanced/advanced-dependencies#dependencies-with-yield-httpexception-except-and-background-tasks). Including what you could do if you wanted to close a database session earlier, before returning the response to the client.
