- Kubeadm: remove the `--port` flag from the manifest for the kube-scheduler since the flag has been a NO-OP since 1.23 and insecure serving was removed for the component. ([#105034](https://github.com/kubernetes/kubernetes/pull/105034), [@pacoxu](https://github.com/pacoxu))...

- Kubeadm: remove the deprecated flag `--insecure-port` from the kube-apiserver manifest that kubeadm manages. The flag had no effect since 1.20, since the insecure serving of the component was disabled in the same version.

- 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))

* Adds a metric apiserver_request_error_total to kube-apiserver. This metric tallies the number of request_errors encountered by verb, group, version, resource, subresource, scope, component, and code.  ([#83427](https://github.com/kubernetes/kubernetes/pull/83427), [@logicalhan](https://github.com/logicalhan))

- Added to `MutableFeatureGate` the ability to override the default setting of feature gates, to allow default-enabling a feature on a component-by-component basis instead of for all affected components simultaneously.
