### Deployment
* **[beta]** Deployments that cannot make progress in rolling out the newest version will now indicate via the API they are blocked ([docs](https://kubernetes.io/docs/user-guide/deployments/#deployment-status))

### Federation

- Switch to VM Update call in attach/detach disk operation, original CreateOrUpdate call may lead to orphaned VMs or blocked resources ([#81208](https://github.com/kubernetes/kubernetes/pull/81208), [@andyzhangx](https://github.com/andyzhangx))
- Fix azure disk naming matching issue due to case sensitive comparison ([#81720](https://github.com/kubernetes/kubernetes/pull/81720), [@andyzhangx](https://github.com/andyzhangx))

- Kubeadm: graduated the kubeadm specific feature gate `UnversionedKubeletConfigMap` to GA and locked it to `true` by default. The kubelet related ConfigMap and RBAC rules are now locked to have a simplified naming `*kubelet-config` instead of the legacy naming `*kubelet-config-x.yy`, where `x.yy` was the version of the control plane. If you have previously used the old naming format with...
