### DNS Autoscaler

    * LUNs being attached, and also deletes them after detaching. This avoids
    * dangling references to LUNs that no longer exist, which used to be the
    * cause of random I/O errors/timeouts in kernel logs, slowdowns during
    * block-device related operations, and very rare cases of data corruption.

  // Set DNS policy for the pod.
  // Defaults to "ClusterFirst".
  // Valid values are 'ClusterFirstWithHostNet', 'ClusterFirst', 'Default' or 'None'.
  // DNS parameters given in DNSConfig will be merged with the policy selected with DNSPolicy.
  // To have DNS options set along with hostNetwork, you have to specify DNS policy
  // explicitly to 'ClusterFirstWithHostNet'.

- Bind dns-horizontal containers to linux nodes to avoid Windows scheduling on kubernetes cluster includes linux nodes and windows nodes ([#83364](https://github.com/kubernetes/kubernetes/pull/83364), [@wawa0210](https://github.com/wawa0210)) [SIG Cluster Lifecycle and Windows]

- This PR sets the --cluster-dns flag value to kube-dns service IP whether or not NodeLocal DNSCache is enabled. NodeLocal DNSCache will listen on both the link-local as well as the service IP. ([#84383](https://github.com/kubernetes/kubernetes/pull/84383), [@prameshj](https://github.com/prameshj))
- kube-dns add-on:
  - All containers are now being executed under more restrictive privileges.

- Fix the bug PIP's DNS is deleted if no DNS label service annotation isn't set. ([#87310](https://github.com/kubernetes/kubernetes/pull/87310), [@nilo19](https://github.com/nilo19)) [SIG Cloud Provider]

- Kubeadm: Remove the field `ClusterConfiguration.DNS.Type` in v1beta3 since CoreDNS is the only supported DNS type. ([#101547](https://github.com/kubernetes/kubernetes/pull/101547), [@neolit123](https://github.com/neolit123))

- `StatefulSet` names must be DNS labels, rather than subdomains. Any `StatefulSet`
  which took advantage of subdomain validation (by having dots in the name) can't
  possibly have worked, because we eventually set `pod.spec.hostname` from the `StatefulSetName`,
