- kubeadm: The ControlPlaneEndpoint was moved from the API config struct to ClusterConfiguration ([#67830](https://github.com/kubernetes/kubernetes/pull/67830), [@fabriziopandini](https://github.com/fabriziopandini))

* kubeadm: Control plane component configs are separated into ClusterConfiguration sub-structs. ([#70371](https://github.com/kubernetes/kubernetes/pull/70371), [@rosti](https://github.com/rosti))

- The `PodDeletionCost` feature has been promoted to beta, and enabled by default. ([#101080](https://github.com/kubernetes/kubernetes/pull/101080), [@ahg-g](https://github.com/ahg-g))
- The `Server Side Apply` treats certain structs as atomic. Meaning the entire selector field is managed by a single writer and updated together. ([#100684](https://github.com/kubernetes/kubernetes/pull/100684), [@Jefftree](https://github.com/Jefftree))

- `klog` text output now uses JSON as encoding for structs, maps and slices. ([#117687](https://github.com/kubernetes/kubernetes/pull/117687), [@pohly](https://github.com/pohly))
- `kube-proxy` in iptables mode will now have separate `sync_full_proxy_rules_duration_seconds`\nand

- The `e2e.test` binary no longer emits JSON structs to document progress. ([#113212](https://github.com/kubernetes/kubernetes/pull/113212), [@pohly](https://github.com/pohly))

- Changed how the API server handles updates to `.spec.defaultBackend` of Ingress objects.

- kube-proxy: a configuration file specified via `--config` is now loaded with strict deserialization, which fails if the config file contains duplicate or unknown fields. This protects against accidentally running with config files that are malformed, mis-indented, or have typos in field names, and getting unexpected behavior. ([...
