--require-kubeconfig flag, removed default --kubeconfig value (([#58367](https://github.com/kubernetes/kubernetes/pull/58367), [@zhangxiaoyu-zidif](https://github.com/zhangxiaoyu-zidif))

* The public-address-override, address, and port flags have been removed and replaced by bind-address, insecure-bind-address, and insecure-port, respectively. They are marked as deprecated in [#36604](https://github.com/kubernetes/kubernetes/pull/36604), which is more than a year ago.  ([#59018](https://github.com/kub...

- The kube-apiserver ability to serve on an insecure port, deprecated since v1.10, has been removed. The insecure address flags `--address` and `--insecure-bind-address` have no effect in kube-apiserver and will be removed in v1.24. The insecure port flags `--port` and `--insecure-port` may only be set to 0 and will be removed in v1.24. ([#95856](https://github.com/kubernetes/kubernetes/pull/95856),...

* Update Azure load balancer to prevent orphaned public IP addresses ([#82890](https://github.com/kubernetes/kubernetes/pull/82890), [@chewong](https://github.com/chewong))

- Kube-apiserver: the insecure address flags `--address`, `--insecure-bind-address`, `--port` and `--insecure-port` (inert since 1.20) are removed ([#106859](https://github.com/kubernetes/kubernetes/pull/106859), [@knight42](https://github.com/knight42))

* Nodes can now report two additional address types in their status: InternalDNS
  and ExternalDNS. The apiserver can use --kubelet-preferred-address-types to
  give priority to the type of address it uses to reach nodes.

#### Bug fixes

### SIG OpenStack

* Provide a meaningful error message in the openstack cloud provider when no valid IP address can be found for a node, rather than just the first address of the node, which leads to a load balancer error if that address is a hostname or DNS name instead of an IP address. ([#64318](https://github.com/kubernetes/kubernetes/pull/64318), [@gonzolino](https://github.com/gonzolino))

* Only use the first IP address got from instance metadata. This is because Azure CNI would set up a list of IP addresses in instance metadata, while only the first one is the Node's IP. ([#71736](https://github.com/kubernetes/kubernetes/pull/71736), [@feiskyer](https://github.com/feiskyer))

* Updated priority of mirror pod according to PriorityClassName. ([#58485](https://github.com/kubernetes/kubernetes/pull/58485), [@k82cn](https://github.com/k82cn))

- Added warnings to the Services API. Kubernetes now warns for Services in the case of:
  - IPv4 addresses with leading zeros
  - IPv6 address in non-canonical format (RFC 5952) ([#114505](https://github.com/kubernetes/kubernetes/pull/114505), [@aojea](https://github.com/aojea))
