- `kubeadm`: Started using a named port `probe-port` for all probes in the static pod manifests generated by `kubeadm` for the `kube-apiserver`, `kube-controller-manager`, `kube-scheduler`, and related components. If probe port values were previously patched using `kubeadm` patches, the corresponding named port under the container’s `ports` field must now also be patched. ([#132776](https://github.com/kubernetes/kubernetes/pull/132776),...

- Added namespace autocompletion for `kubectl config set-context` command. ([#124994](https://github.com/kubernetes/kubernetes/pull/124994), [@TessaIO](https://github.com/TessaIO)) [SIG CLI]
- Added ports autocompletion for kubectl port-foward command. ([#124683](https://github.com/kubernetes/kubernetes/pull/124683), [@TessaIO](https://github.com/TessaIO)) [SIG CLI]

- Fixed an issue with Kubernetes-style sidecar containers (in other words: init containers 
with an Always restart policy) and Services. Before the fix, named ports 
exposed by a sidecar could not be accessed using a Service. ([#128850](https://github.com/kubernetes/kubernetes/pull/128850), [@toVersus](https://github.com/toVersus)) [SIG Network and Testing]

- 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]
