- Component-base: make the validation logic about LeaderElectionConfiguration consistent between component-base and client-go ([#111758](https://github.com/kubernetes/kubernetes/pull/111758), [@SataQiu](https://github.com/SataQiu)) [SIG API Machinery and Scheduling]

MUST read this before you upgrade)

- Stopped accepting component configuration for `kube-proxy` and `kubelet` during `kubeadm upgrade plan --config`. This was a legacy behavior that was not well supported for upgrades and could be used only at the plan stage to determine if the configuration for these components stored in the cluster needs manual version migration. In the future, `kubeadm` will attempt alternative component config migration approaches. ([#120788](https://github.com/kube...

    /* DFS */

    /* Split DFS path like \fs1.example.com\root5\link2\foo\bar.txt into at
     * most 3 components (not including the first index which is always empty):
     * result[0] = ""

さらに、Starletteのすべてのセキュリティ機能も含みます（**セッションCookie**を含む）。

これらは、システム、データストア、リレーショナルデータベース、NoSQLデータベースなどと簡単に統合できる再利用可能なツールとコンポーネントとして構築されています。

### 依存性の注入（Dependency Injection）

FastAPIには非常に使いやすく、非常に強力な<abbr title='also known as "components", "resources", "services", "providers"'><strong>依存性の注入</strong></abbr>システムを備えています。

* 依存関係でさえも依存関係を持つことができ、階層または **依存関係の"グラフ"** を作成することができます。

* フレームワークによってすべて**自動的に処理**されます。

### Other notable changes

* kube-up (with gce/gci and gce/coreos providers) now ensures the authentication token file contains correct tokens for the control plane components, even if the file already exists (ensures upgrades and downgrades work successfully) ([#43676](https://github.com/kubernetes/kubernetes/pull/43676), [@liggitt](https://github.com/liggitt))
