 ## Latest Changes
 
+## 0.106.0
+
+### Breaking Changes
+
+Using resources from dependencies with `yield` in background tasks is no longer supported.
+
+This change is what supports the new features, read below. 🤓
+
+### Dependencies with `yield`, `HTTPException` and Background Tasks
+
+Dependencies with `yield` now can raise `HTTPException` and other exceptions after `yield`. 🎉
+
+Read the new docs here: [Dependencies with `yield` and `HTTPException`](https://fastapi.tiangolo.com/tutorial/dependencies/dependencies-with-yield/#dependencies-with-yield-and-httpexception).
+
+```Python
+from fastapi import Depends, FastAPI, HTTPException
+from typing_extensions import Annotated
+
+app = FastAPI()
+
+
+data = {
+    "plumbus": {"description": "Freshly pickled plumbus", "owner": "Morty"},
+    "portal-gun": {"description": "Gun to create portals", "owner": "Rick"},
+}
+
+
+class OwnerError(Exception):
+    pass
+
+
+def get_username():
+    try:
+        yield "Rick"
+    except OwnerError as e:
+        raise HTTPException(status_code=400, detail=f"Onwer error: {e}")
+
+
+@app.get("/items/{item_id}")
+def get_item(item_id: str, username: Annotated[str, Depends(get_username)]):
+    if item_id not in data:
+        raise HTTPException(status_code=404, detail="Item not found")
+    item = data[item_id]
+    if item["owner"] != username:
+        raise OwnerError(username)
+    return item
+```
+
+---
+
+Before FastAPI 0.106.0, raising exceptions after `yield` was not possible, the exit code in dependencies with `yield` was executed *after* the response was sent, so [Exception Handlers](https://fastapi.tiangolo.com/tutorial/handling-errors/#install-custom-exception-handlers) would have already run.
+
+This was designed this way mainly to allow using the same objects "yielded" by dependencies inside of background tasks, because the exit code would be executed after the background tasks were finished.
+
+Nevertheless, as this would mean waiting for the response to travel through the network while unnecessarily holding a resource in a dependency with yield (for example a database connection), this was changed in FastAPI 0.106.0.
+
+Additionally, a background task is normally an independent set of logic that should be handled separately, with its own resources (e.g. its own database connection).
+
+If you used to rely on this behavior, now you should create the resources for background tasks inside the background task itself, and use internally only data that doesn't depend on the resources of dependencies with `yield`.
+
+For example, instead of using the same database session, you would create a new database session inside of the background task, and you would obtain the objects from the database using this new session. And then instead of passing the object from the database as a parameter to the background task function, you would pass the ID of that object and then obtain the object again inside the background task function.
+
+The sequence of execution before FastAPI 0.106.0 was like this diagram:
+
+Time flows from top to bottom. And each column is one of the parts interacting or executing code.

+    Note over dep: After yield
+    opt Handle other exception
+        dep -->> dep: Handle exception, can't change response. E.g. close DB session.
+    end
+```

-It might be tempting to raise an `HTTPException` or similar in the exit code, after the `yield`. But **it won't work**.
-
-The exit code in dependencies with `yield` is executed *after* the response is sent, so [Exception Handlers](../handling-errors.md#install-custom-exception-handlers){.internal-link target=_blank} will have already run.

-
-So, if you raise an `HTTPException` after the `yield`, the default (or any custom) exception handler that catches `HTTPException`s and returns an HTTP 400 response won't be there to catch that exception anymore.
-
-This is what allows anything set in the dependency (e.g. a DB session) to, for example, be used by background tasks.
-
-Background tasks are run *after* the response has been sent. So there's no way to raise an `HTTPException` because there's not even a way to change the response that is *already sent*.
-
-But if a background task creates a DB error, at least you can rollback or cleanly close the session in the dependency with `yield`, and maybe log the error or report it to a remote tracking system.
-
-If you have some code that you know could raise an exception, do the most normal/"Pythonic" thing and add a `try` block in that section of the code.
-
-If you have custom exceptions that you would like to handle *before* returning the response and possibly modifying the response, maybe even raising an `HTTPException`, create a [Custom Exception Handler](../handling-errors.md#install-custom-exception-handlers){.internal-link target=_blank}.

+
+!!! warning
+    You most probably don't need these technical details, you can skip this section and continue below.
+
+    These details are useful mainly if you were using a version of FastAPI prior to 0.106.0 and used resources from dependencies with `yield` in background tasks.
