* The init-container (pod.beta.kubernetes.io/init-containers) annotations used to accept capitalized field names that could be accidentally generated by the k8s.io/kubernetes/pkg/api package. Using an upper case field name will now return an error and all users should use the versioned API types from `pkg/api/v1` when serializing from Golang.

## Action Required Before Upgrading

* Important Security-related changes before upgrading

- The v1 Endpoints API is now officially deprecated (though still fully supported). The API will not be removed, but all users should use the EndpointSlice API instead.

### API Change

### API Change

- A new `preEnqueue` extension point is added to scheduler's component config v1beta2/v1beta3/v1. ([#113275](https://github.com/kubernetes/kubernetes/pull/113275), [@Huang-Wei](https://github.com/Huang-Wei)) [SIG API Machinery, Apps, Instrumentation, Scheduling and Testing]

# 조건부적인 OpenAPI

필요한 경우, 설정 및 환경 변수를 사용하여 환경에 따라 조건부로 OpenAPI를 구성하고 완전히 비활성화할 수도 있습니다.

## 보안, API 및 docs에 대해서

프로덕션에서, 문서화된 사용자 인터페이스(UI)를 숨기는 것이 API를 보호하는 방법이 *되어서는 안 됩니다*.

이는 API에 추가적인 보안을 제공하지 않으며, *경로 작업*은 여전히 동일한 위치에서 사용 할 수 있습니다.

코드에 보안 결함이 있다면, 그 결함은 여전히 존재할 것입니다.

### Deprecation warnings

SIG API Machinery implemented [warnings when using deprecated APIs](https://kubernetes.io/docs/reference/using-api/deprecation-policy/#rest-resources-aka-api-objects)
that are visible to `kubectl` users and API consumers, and metrics visible to cluster administrators.
Requests to a deprecated API are returned with a warning containing a target removal release and any replacement API.

* The `PodSecurityPolicy` API has been moved to the `policy/v1beta1` API group. The `PodSecurityPolicy` API in the `extensions/v1beta1` API group is deprecated and will be removed in a future release. Authorizations for using pod security policy resources should change to reference the `policy` API group after upgrading to 1.11.
