  * Add `kubectl rollout status`
* Security/Auth
  * L7 LB controller and disk attach controllers run on master, so nodes do not need those privileges.
  * Setting TLS1.2 minimum
  * `kubectl create secret tls` command
  * Webhook Token Authenticator
  * **beta** PodSecurityPolicy objects limits use of security-sensitive features by pods.
* Kubectl
  * Display line number on JSON errors

* [fluentd-gcp-scaler addon] Bump fluentd-gcp-scaler to 0.4 to pick up security fixes. ([#67691](https://github.com/kubernetes/kubernetes/pull/67691), [@loburm](https://github.com/loburm))
    * [prometheus-to-sd addon] Bump prometheus-to-sd to 0.3.1 to pick up security fixes, bug fixes and new features.
    * [event-exporter addon] Bump event-exporter to 0.2.3 to pick up security fixes.

    * It will also be used by automatic client code generation tools.

But most importantly:

* It will **limit and filter** the output data to what is defined in the return type.
    * This is particularly important for **security**, we'll see more of that below.

## `response_model` Parameter { #response-model-parameter }

There are some cases where you need or want to return some data that is not exactly what the type declares.

これはユーザーモデルの場合は特にそうです。なぜなら:

* **入力モデル** にはパスワードが必要です。
* **出力モデル**はパスワードをもつべきではありません。
* **データベースモデル**はおそらくハッシュ化されたパスワードが必要になるでしょう。

/// danger | 危険

ユーザーの平文のパスワードは絶対に保存しないでください。常に認証に利用可能な「安全なハッシュ」を保存してください。

知らない方は、[セキュリティの章](security/simple-oauth2.md#password-hashing){.internal-link target=_blank}で「パスワードハッシュ」とは何かを学ぶことができます。

## 複数のモデル

ここでは、パスワードフィールドをもつモデルがどのように見えるのか、また、どこで使われるのか、大まかなイメージを紹介します:

Todos os esquemas de seguranças definidos no OpenAPI, incluindo:

* HTTP Basic.
* **OAuth2** (também com **tokens JWT**). Confira o tutorial em [OAuth2 com JWT](tutorial/security/oauth2-jwt.md){.internal-link target=_blank}.
* Chaves de API em:
    * Headers.
    * parâmetros da Query.
    * Cookies etc.
