- Kube-controller-manager: Fixes bug setting headless service labels on endpoints ([#85361](https://github.com/kubernetes/kubernetes/pull/85361),...

## Deprecations and Removals

- API

  - The following APIs are no longer served by default:

    - All resources under `apps/v1beta1` and `apps/v1beta2` - use `apps/v1` instead
    - `daemonsets`, `deployments`, `replicasets` resources under `extensions/v1beta1` - use `apps/v1` instead
    - `networkpolicies` resources under `extensions/v1beta1` - use `networking.k8s.io/v1` instead

さらに、Pythonが**データサイエンス**、機械学習、特にディープラーニングの主要言語であるという単純な事実により、FastAPIはデータサイエンス/機械学習のWeb APIおよびアプリケーション (他の多くのアプリケーションとの) に非常によく適合しています。

本番環境でこの並列処理を実現する方法については、[デプロイ](deployment/index.md){.internal-link target=_blank}に関するセクションを参照してください。

## `async` と `await`

現代的なバージョンのPythonには、非同期コードを定義する非常に直感的な方法があります。これにより、通常の「シーケンシャル」コードのように見え、適切なタイミングで「待機」します。

- Previous versions of Kubernetes on Google Cloud required that workloads (e.g. Deployments, DaemonSets, etc.) which used `PersistentDisk` volumes were using them in read-only mode.  This validation provided very little value at relatively host implementation cost, and will no longer be validated.  If this is a problem for a specific use-case,...

- Kube-proxy handles Terminating EndpointSlices conditions and enables zero downtime deployments for Services with ExternalTrafficPolicy=Local author: @andrewsykim ([#117718](https://github.com/kubernetes/kubernetes/pull/117718), [@aojea](https://github.com/aojea)) [SIG Network, Testing and Windows]

- Implemented a new status field, `.status.terminatingReplicas`, for Deployments and ReplicaSets to track terminating pods. The new field is present when the `DeploymentPodReplacementPolicy` feature gate is enabled. ([#128546](https://github.com/kubernetes/kubernetes/pull/128546), [@atiratree](https://github.com/atiratree))...

alpha, is no longer available. Kubernetes now only uses the _structured parameters_ model (also alpha) for allocating dynamic resources to Pods.

  if and only if classic DRA was enabled in a cluster, remove all workloads (pods, app deployments, etc. ) which depend on classic DRA and make sure that all PodSchedulingContext resources are gone before upgrading. PodSchedulingContext resources cannot be removed through the apiserver after an upgrade and workloads would not work properly. ...

Starletteや**FastAPI**のサーバーとして推奨されています。

/// check | **FastAPI**が推奨する理由

**FastAPI**アプリケーションを実行するメインのウェブサーバーである点。

Gunicornと組み合わせることで、非同期でマルチプロセスなサーバーを持つことがきます。

## ベンチマーク と スピード

### Bug or Regression

- (PodSecurity admission) errors validating workload resources (deployment, replicaset, etc.) no longer block admission. ([#106017](https://github.com/kubernetes/kubernetes/pull/106017), [@tallclair](https://github.com/tallclair)) [SIG Auth]

With cluster-wide seccomp defaults, the kubelet uses the `RuntimeDefault` seccomp profile by default, rather than than `Unconfined`. This allows enhancing the default cluster wide workload security of the Kubernetes deployment. Security administrators will now sleep better knowing there is some security by default for the workloads.
