Centrémonos en los parámetros declarados:

* Aunque esta función es una dependencia ("dependable") en sí misma, también declara otra dependencia (depende de algo más).
    * Depende del `query_extractor`, y asigna el valor que devuelve al parámetro `q`.
* También declara una `last_query` cookie opcional, como un `str`.

* Federation can now be deployed using the `federation/deploy/deploy.sh` script. This script does not depend on any of the development environment shell library/scripts. This is an alternative to the current `federation-up.sh`/`federation-down.sh` scripts. Both the scripts are going to co-exist in this release, but the `federation-up.sh`/`federation-down.sh`...

Vamos focar nos parâmetros declarados:

* Mesmo que essa função seja uma dependência ("dependable") por si mesma, ela também declara uma outra dependência (ela "depende" de outra coisa).
    * Ela depende do `query_extractor`, e atribui o valor retornado pela função ao parâmetro `q`.
* Ela também declara um cookie opcional `last_query`, do tipo `str`.

* The `PersistentVolumeLabel` admission controller is now disabled by default. If you depend on this feature (AWS/GCE) then ensure it is added to the `--enable-admission-plugins` flag on the kube-apiserver.

En la versión 0.121.0, FastAPI agregó soporte para `Depends(scope="function")` para dependencias con `yield`.

Usando `Depends(scope="function")`, el código de salida después de `yield` se ejecuta justo después de que la *path operation function* termina, antes de que la response se envíe de vuelta al cliente.

from fastapi import APIRouter, Depends, FastAPI, WebSocket

def dependency_list() -> list[str]:
    return []


DepList = Annotated[list[str], Depends(dependency_list)]


def create_dependency(name: str):
    def fun(deps: DepList):
        deps.append(name)

    return Depends(fun)

The merged fix enforces validation against the proxying address for a Node. In some cases, the fix can break clients that depend on the `nodes/proxy` subresource, specifically if a kubelet advertises a localhost or link-local address to the Kubernetes control plane. Configuring an egress proxy for egress to the cluster network can also mitigate this vulnerability.
