- 'Promoted `cronjob_job_creation_skew` metric to stable to follow the cronjob v2 controller,
  the following metrics had their name updated to match metrics API guidelines:
    - `cronjob_job_creation_skew_duration_seconds` -> `job_creation_skew_duration_seconds`.' ([#113008](https://github.com/kubernetes/kubernetes/pull/113008), [@soltysh](https://github.com/soltysh))

Besides the above new features, support for Azure Virtual Machine Scale Sets (VMSS) and Cluster-Autoscaler is now stable and considered GA:

- Azure virtual machine scale sets (VMSS) allow you to create and manage identical load balanced VMs that automatically increase or decrease based on demand or a set schedule.

### <a href="https://apispec.readthedocs.io/en/stable/" class="external-link" target="_blank">APISpec</a>

MarshmallowとWebargsはバリデーション、パース、シリアライゼーションをプラグインとして提供しています。

しかし、ドキュメントはまだ不足しています。そこでAPISpecが作られました。

これは多くのフレームワーク用のプラグインです (Starlette用のプラグインもあります) 。

- Promoted `AdmissionWebhookMatchConditions` to GA. The feature is now stable, and the feature gate is now locked to default.
