- CCM server will not listen insecurely if secure port is specified ([#68982](https://github.com/kubernetes/kubernetes/pull/68982), [@aruneli](https://github.com/aruneli))

  * Maintain a cache of all instances, to fix problem with > 200 nodes with ELBs ([#47410](https://github.com/kubernetes/kubernetes/pull/47410), [@justinsb](https://github.com/justinsb))

  * Avoid spurious ELB listener recreation - ignore case when matching protocol ([#47391](https://github.com/kubernetes/kubernetes/pull/47391), [@justinsb](https://github.com/justinsb))

- Added support to the kube-proxy nodePortAddresses / --nodeport-addresses option to
  accept the value "primary", meaning to only listen for NodePort connections
  on the node's primary IPv4 and/or IPv6 address (according to the Node object).
  This is strongly recommended, if you were not previously using
  --nodeport-addresses, to avoid surprising behavior.

* Allow kube- and cloud-controller-manager to listen on ports up to 65535. ([#65860](https://github.com/kubernetes/kubernetes/pull/65860), [@sttts](https://github.com/sttts))
* Allow kube-scheduler to listen on ports up to 65535. ([#65833](https://github.com/kubernetes/kubernetes/pull/65833), [@sttts](https://github.com/sttts))

- Add --permit-address-sharing flag to `kube-apiserver` to listen with `SO_REUSEADDR`. While allowing to listen on wildcard IPs like 0.0.0.0 and specific IPs in parallel, it avoids waiting for the kernel to release socket in `TIME_WAIT` state, and hence, considerably reducing `kube-apiserver` restart times under certain conditions. (...

- 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:

* You can now have services that listen on the same host ports on different interfaces by specifying `--nodeport-addresses`. ([#62003](https://github.com/kubernetes/kubernetes/pull/62003), [@m1093782566](https://github.com/m1093782566))
* Added port-forward examples for service
