- The kubelet now creates an iptables chain named `KUBE-IPTABLES-HINT` in
  the `mangle` table. Containerized components that need to modify iptables
  rules in the host network namespace can use the existence of this chain
  to more-reliably determine whether the system is using iptables-legacy or

- The Go API for logging configuration in `k8s.io/component-base` was moved to `k8s.io/component-base/logs/api/v1`. The configuration file format and command line flags are the same as before. ([#105797](https://github.com/kubernetes/kubernetes/pull/105797), [@pohly](https://github.com/pohly))

- Stopped accepting component configuration for `kube-proxy` and `kubelet` during `kubeadm upgrade plan --config`. This was a legacy behavior that was not well supported for upgrades and could be used only at the plan stage to determine if the configuration for these components stored in the cluster needs manual version migration. In the future, `kubeadm` will attempt alternative component config migration approaches. ([#120788](https://github.com/kube...
