Usar `UploadFile` tiene varias ventajas sobre `bytes`:

* No tienes que usar `File()` en el valor por defecto del parámetro.
* Usa un archivo "spooled":
    * Un archivo almacenado en memoria hasta un límite de tamaño máximo, y después de superar este límite, se almacenará en el disco.
* Esto significa que funcionará bien para archivos grandes como imágenes, videos, binarios grandes, etc. sin consumir toda la memoria.
* Puedes obtener metadatos del archivo subido.

* The `system-node-critical` and `system-cluster-critical` priority classes are now limited to the `kube-system` namespace by the `PodPriority` admission plugin. ([#65593](https://github.com/kubernetes/kubernetes/pull/65593), [@bsalamat](https://github.com/bsalamat))

# Release 2.20.0

## TensorFlow

### Breaking Changes

* The `tensorflow-io-gcs-filesystem` package is now optional, due its uncertain, and limited support. To install it alongside `tensorflow`, run `pip install "tensorflow[gcs-filesystem]"`.

### Major Features and Improvements

* The `NodeRestriction` admission plugin limits the `Node` and `Pod` objects a kubelet can modify. In order to be limited by this admission plugin, kubelets must use credentials in the `system:nodes` group, with a username in the form `system:node:<nodeName>`. Such kubelets will only be allowed to modify their own `Node` API object, and only modify `Pod` API objects...
