You most probably don't need these technical details.
These details are useful mainly if you had a FastAPI application older than 0.118.0 and you are facing issues with dependencies with `yield`.

Dependencies with `yield` have evolved over time to account for the different use cases and to fix some issues, here's a summary of what has changed.
### Dependencies with `yield` and `scope` { #dependencies-with-yield-and-scope }
In version 0.121.0, FastAPI added support for `Depends(scope="function")` for dependencies with `yield`.
Using `Depends(scope="function")`, the exit code after `yield` is executed right after the *path operation function* is finished, before the response is sent back to the client.
And when using `Depends(scope="request")` (the default), the exit code after `yield` is executed after the response is sent.
You can read more about it in the docs for [Dependencies with `yield` - Early exit and `scope`](../tutorial/dependencies/dependencies-with-yield.md#early-exit-and-scope).
### Dependencies with `yield` and `StreamingResponse`, Technical Details { #dependencies-with-yield-and-streamingresponse-technical-details }
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.
