- kube-apiserver `--admission-control-config-file` files are now validated strictly (EnableStrict). Duplicate and unknown fields in the configuration will now cause an error. ([#128013](https://github.com/kubernetes/kubernetes/pull/128013), [@seans3](https://github.com/seans3))

<p>
A type is <i>strictly comparable</i> if it is comparable and not an interface
type nor composed of interface types.
Specifically:
</p>

<ul>
	<li>
	Boolean, numeric, string, pointer, and channel types are strictly comparable.
	</li>

	<li>
	Struct types are strictly comparable if all their field types are strictly comparable.
	</li>

- Added a new option `strict-cpu-reservation` for CPU Manager static policy. When this option is enabled, CPU cores in `reservedSystemCPUs` will be strictly used for system daemons and interrupt processing no longer available for any workload.

- 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. ([...

- Custom resource requests with `fieldValidation=Strict` consistently require `apiVersion` and `kind`, matching non-strict requests ([#109019](https://github.com/kubernetes/kubernetes/pull/109019), [@liggitt](https://github.com/liggitt))

- Promoted meta.k8s.io/v1beta1 Table and PartialObjectMetadata to v1. ([#77136](https://github.com/kubernetes/kubernetes/pull/77136), [@smarterclayton](https://github.com/smarterclayton))

* [IPVS] Allow for transparent kube-proxy restarts ([#75283](https://github.com/kubernetes/kubernetes/pull/75283), [@lbernail](https://github.com/lbernail))

- Kubeadm: Strictly enabled only the supported klog flags, disallowing previously available but unrecommended options. This means that hidden flags about klog (including `--alsologtostderr`, `--log-backtrace-at`, `--log-dir`, `--logtostderr`, `--log-file`, `--log-file-max-size`,...

* fix azure disk list corruption issue ([#77187](https://github.com/kubernetes/kubernetes/pull/77187), [@andyzhangx](https://github.com/andyzhangx))
