- Kubeadm: removed the toleration for the `node-role.kubernetes.io/master` taint from the CoreDNS deployment of `kubeadm`. With the 1.25 release of kubeadm the taint `node-role.kubernetes.io/master` is no longer applied to control plane nodes and the toleration for it can be removed with the release of 1.26. You can also perform the same toleration removal from your own addon manifests. ([#112008](https://github.com/kubernetes/kubernetes/pull/112008),...

- Clarified an API validation error for toleration if `operator` is `Exists` and `value` is not empty. ([#128119](https://github.com/kubernetes/kubernetes/pull/128119), [@saschagrunert](https://github.com/saschagrunert)) [SIG API Machinery and Apps]

* After 1.8, admission controller will add 'MemoryPressure' toleration to Guaranteed and Burstable pods. ([#50180](https://github.com/kubernetes/kubernetes/pull/50180), [@k82cn](https://github.com/k82cn))

# Path Operationの設定

*path operationデコレータ*を設定するためのパラメータがいくつかあります。

/// warning | "注意"

これらのパラメータは*path operation関数*ではなく、*path operationデコレータ*に直接渡されることに注意してください。

///

## レスポンスステータスコード

*path operation*のレスポンスで使用する（HTTP）`status_code`を定義することができます。

`404`のように`int`のコードを直接渡すことができます。

しかし、それぞれの番号コードが何のためのものか覚えていない場合は、`status`のショートカット定数を使用することができます:

```Python hl_lines="3  17"

# Path Operation Configuration

There are several parameters that you can pass to your *path operation decorator* to configure it.

/// warning

Notice that these parameters are passed directly to the *path operation decorator*, not to your *path operation function*.

///

## Response Status Code

You can define the (HTTP) `status_code` to be used in the response of your *path operation*.

You can pass directly the `int` code, like `404`.
