* Rename *path operation decorator* parameter `content_type` to `response_class`. PR [#183](https://github.com/tiangolo/fastapi/pull/183).

* Add docs:
    * How to use the `jsonable_encoder` in [JSON compatible encoder](https://fastapi.tiangolo.com/tutorial/encoder/).
    * How to [Return a Response directly](https://fastapi.tiangolo.com/advanced/response-directly/).

The return value of <code>recover</code> is <code>nil</code> when the
goroutine is not panicking or <code>recover</code> was not called directly by a deferred function.
Conversely, if a goroutine is panicking and <code>recover</code> was called directly by a deferred function,
the return value of <code>recover</code> is guaranteed not to be <code>nil</code>.

- `kubeadm`: improved the logic that checks whether a `systemd` service exists. ([#120514](https://github.com/kubernetes/kubernetes/pull/120514), [@fengxsong](https://github.com/fengxsong))
- `kubeadm`: will now use universal deserializer to decode static pod. ([#120549](https://github.com/kubernetes/kubernetes/pull/120549), [@pacoxu](https://github.com/pacoxu))
- `kubectl prune v2`: Switched annotation from `contains-group-resources` to `contains-group-kinds`,

- Kube-apiserver: errors decoding objects in etcd are now recorded in an `apiserver_storage_decode_errors_total` counter metric ([#114376](https://github.com/kubernetes/kubernetes/pull/114376), [@baomingwang](https://github.com/baomingwang)) [SIG API Machinery and Instrumentation]

  // scheduled right away as preemption victims receive their graceful termination periods.

  // to place the pod elsewhere if other nodes become available sooner. Scheduler may also decide to
  // give the resources on this node to a higher priority pod that is created after preemption.
