## Detailed Bug Fixes And Changes

### API Machinery

- client-go: `PortForwarder.GetPorts()` now contain correct local port if no local port was initially specified when setting up the port forwarder ([#73676](https://github.com/kubernetes/kubernetes/pull/73676), [@martin-helmich](https://github.com/martin-helmich))

- Kube-proxy will no longer hold service node ports open on the node. Users are still advised not to run any listener on node ports range used by kube-proxy. ([#108496](https://github.com/kubernetes/kubernetes/pull/108496), [@khenidak](https://github.com/khenidak))

func getHostsSlice(records []dns.SrvRecord) []string {
	hosts := make([]string, len(records))
	for i, r := range records {
		hosts[i] = net.JoinHostPort(r.Host, string(r.Port))
	}
	return hosts
}

// returns an online host (and corresponding port) from a slice of DNS records
func getHostFromSrv(records []dns.SrvRecord) (host string) {
	hosts := getHostsSlice(records)

 
## Changes by Kind

### Deprecation

- Controller-manager: the following flags have no effect and would be removed in v1.24:
  - `--port`
  - `--address`
  The insecure port flags `--port` may only be set to 0 now.
  
  In addtion, please be careful that:

			"in the secret. If a name is not specified the kube-system namespace's UUID of "+
			"the local cluster will be used.")
	flagset.StringVar(&o.ServerOverride, "server", "",
		"The address and port of the Kubernetes API server.")
	flagset.StringVar(&o.SecretName, "secret-name", "",
		"The name of the specific secret to use from the service-account. Needed when there are multiple secrets in the service account.")

  by default, that prevented the control plane's pod garbage collector from deleting
  pods that contained duplicated field keys (environmental variables with repeated keys or
  container ports). ([#121103](https://github.com/kubernetes/kubernetes/pull/121103), [@mimowo](https://github.com/mimowo))

- Added warning for dup ports update/patching in pod's container ports and service ports. ([#113245](https://github.com/kubernetes/kubernetes/pull/113245), [@pacoxu](https://github.com/pacoxu))
