- `kubeadm`: now respects user provided `kubeconfig` during discovery process ([#113998](https://github.com/kubernetes/kubernetes/pull/113998), [@SataQiu](https://github.com/SataQiu))
- `kubectl port-forward` now exits with exit code 1 when remote connection is
  lost ([#114460](https://github.com/kubernetes/kubernetes/pull/114460), [@brianpursley](https://github.com/brianpursley))

This was designed this way mainly to allow using the same objects "yielded" by dependencies inside of background tasks, because the exit code would be executed after the background tasks were finished.

- Added a new `--init-only` command line flag to `kube-proxy`. Setting the flag makes `kube-proxy` perform its initial configuration that requires privileged mode, and then exit. The `--init-only` mode is intended to be executed in a privileged init container, so that the main container may run with a stricter `securityContext`.

- `kubectl get` no longer exits before printing all of its results if an error is found ([#70311](https://github.com/kubernetes/kubernetes/pull/70311), [@juanvallejo](https://github.com/juanvallejo))

containers can be added to running pods for purposes such as debugging, similar to how `kubectl exec` runs a process in an existing container. Also like `kubectl exec`, no resources are reserved for ephemeral containers and they are not restarted when they exit. Note that container namespace targeting is not yet implemented, so [process namespace sharing](https://kubernetes.io/docs/tasks/configure-pod-container/share-process-namespace/) must be enabled to view process from other containers in the pod.
