## 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:

- Reset streams when an error happens during port-forward allowing kubectl to maintain port-forward connection open. ([#128318](https://github.com/kubernetes/kubernetes/pull/128318), [@soltysh](https://github.com/soltysh)) [SIG API Machinery, CLI and Node]

## 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))

  that prevented the control plane's pod garbage collector from deleting pods that contained duplicated field keys (env. variables with repeated keys or container ports).
