## Changes by Kind

### API Change

- Fixes a 1.30.0 regression in openapi descriptions of imagePullSecrets and hostAliases fields to mark the fields used as keys in those lists as either defaulted or required. ([#124553](https://github.com/kubernetes/kubernetes/pull/124553), [@pmalek](https://github.com/pmalek)) [SIG API Machinery]

const (

 *  New: `ConnectionPool.setPolicy()` configures a minimum connection pool size for a target
    address. Use this to proactively open HTTP connections.

    Connections opened to fulfill this policy are subject to the connection pool's
    `keepAliveDuration` but do not count against the pool-wide `maxIdleConnections` limit.

// Copy copies the file f (obtained from a [Reader]) into w. It copies the raw
// form directly bypassing decompression, compression, and validation.
func (w *Writer) Copy(f *File) error {
	r, err := f.OpenRaw()
	if err != nil {
		return err

	// Copy the FileHeader so w doesn't store a pointer to the data
	// of f's entire archive. See #65499.

- Fixed a 1.30.0 regression in OpenAPI descriptions of the `imagePullSecrets` and 
  `hostAliases` fields to mark the fields used as keys in those lists as either defaulted
  or required. ([#124553](https://github.com/kubernetes/kubernetes/pull/124553), [@pmalek](https://github.com/pmalek))

* **Data te valideren**: afkomstig van elke request:
    * **Automatische foutmeldingen** te genereren die naar de client worden geretourneerd wanneer de data ongeldig is.
* De API met OpenAPI te **documenteren**:
    * die vervolgens wordt gebruikt door de automatische interactieve documentatie gebruikersinterfaces.

* **要件の定義**: リクエストパスパラメータ、クエリパラメータ、ヘッダー、ボディ、依存関係などから要件を定義します。
* **データの変換**: リクエストのデータを必要な型に変換します。
* **データの検証**: リクエストごとに:
    * データが無効な場合にクライアントに返される **自動エラー** を生成します。
* **ドキュメント** OpenAPIを使用したAPI:
    * 自動的に対話型ドキュメントのユーザーインターフェイスで使用されます。

すべてが抽象的に聞こえるかもしれません。心配しないでください。 この全ての動作は [チュートリアル - ユーザーガイド](tutorial/index.md){.internal-link target=_blank}で見ることができます。

* Remove a release-note on multiple OpenAPI specs ([#38732](https://github.com/kubernetes/kubernetes/pull/38732), [@mbohlool](https://github.com/mbohlool))
* genericapiserver: unify swagger and openapi in config ([#38690](https://github.com/kubernetes/kubernetes/pull/38690), [@sttts](https://github.com/sttts))

* **Kiểm tra tính đúng đắn của dữ liệu**: tới từ mỗi request:
    * Sinh **lỗi tự động** để trả về máy khác khi dữ liệu không hợp lệ.
* **Tài liệu hóa** API sử dụng OpenAPI:
    * cái mà sau được được sử dụng bởi tài liệu tương tác người dùng.
