- Kubeadm now distinguishes between generated and user supplied component configs, regenerating the former ones if a config upgrade is required ([#86070](https://github.com/kubernetes/kubernetes/pull/86070), [@rosti](https://github.com/rosti)) [SIG Cluster Lifecycle]

- 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. ([#102121](https://github.com/kubernetes/kubernetes/pull/102121), [@pacoxu](https://github.com/pacoxu))

- Added new k8s.io/component-helpers repository providing shared helper code for (core) components. ([#92507](https://github.com/kubernetes/kubernetes/pull/92507), [@ingvagabund](https://github.com/ingvagabund)) [SIG Apps, Node, Release and Scheduling]

- 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))

## Changelog since v1.23.0

## Major Themes

### Dockershim Removed from kubelet

After its deprecation in v1.20, the dockershim component has been removed from the kubelet.
From v1.24 onwards, you will need to either use one of the other [supported runtimes](https://kubernetes.io/docs/setup/production-environment/container-runtimes/) (such as containerd or CRI-O)

* 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. ([#122647](https://github.com/kubernetes/kubernetes/pull/122647), [@benluddy](https://github.com/benluddy))

### Cluster Lifecycle

* Scheduler treats StatefulSet pods as belonging to a single equivalence class. ([#39718](https://github.com/kubernetes/kubernetes/pull/39718), [@foxish](https://github.com/foxish))
* Update FitError as a message component into the PodConditionUpdater. ([#39491](https://github.com/kubernetes/kubernetes/pull/39491), [@jayunit100](https://github.com/jayunit100))
