- Azure VMSS/VMSSVM clients now suppress requests on throttling ([#86740](https://github.com/kubernetes/kubernetes/pull/86740), [@feiskyer](https://github.com/feiskyer)) [SIG Cloud Provider]
- Azure cloud provider cache TTL is configurable, list of the azure cloud provider is as following:
  - "availabilitySetNodesCacheTTLInSeconds"
  - "vmssCacheTTLInSeconds"
  - "vmssVirtualMachinesCacheTTLInSeconds"
  - "vmCacheTTLInSeconds"

    * A new `k8s_external` plugin that allows external zones to point to Kubernetes in-cluster services.
    * CoreDNS now checks if a zone transfer is allowed. Also allow a TTL of 0 to avoid caching in the cache plugin.
    * TTL is also applied to negative responses (NXDOMAIN, etc).

- util/initsystem: Added support for the OpenRC init system ([#73101](https://github.com/kubernetes/kubernetes/pull/73101), [@oz123](https://github.com/oz123))
- Default TTL for DNS records in kubernetes zone has been changed from 5s to 30s to keep consistent with old dnsmasq based kube-dns. The TTL can be customized with command `kubectl edit -n kube-system configmap/coredns`. ([#76238](https://github.com/kubernetes/kubernetes/pull/76238), [@Dieken](https://github.com/Dieken))

  or `Secrets` when the `configMapAndSecretChangeDetectionStrategy` is set to `Cache`.
  The update interval is only affected by `node.alpha.kubernetes.io/ttl` node annotation." ([#120255](https://github.com/kubernetes/kubernetes/pull/120255), [@likakuli](https://github.com/likakuli))
