- Kubelet could be run with no Azure identity without subscriptionId configured now.
  A sample cloud provider configure is: '{"vmType": "vmss", "useInstanceMetadata": true}'. ([#81500](https://github.com/kubernetes/kubernetes/pull/81500), [@feiskyer](https://github.com/feiskyer))

- Ensured that the Node Admission plugin to reject CSR requests created by a node identity for the signers `kubernetes.io/kubelet-serving` or `kubernetes.io/kube-apiserver-client-kubelet` with a CN starting with `system:node:`, but where the CN is not `system:node:${node-name}`. The feature gate `AllowInsecureKubeletCertificateSigningRequests`...
