- Kubeadm: fixed an etcd learner-mode bug by preparing an etcd static pod manifest before promoting ([#115038](https://github.com/kubernetes/kubernetes/pull/115038), [@tobiasgiese](https://github.com/tobiasgiese))

- Kubeadm: add support for dry running "kubeadm reset". The new flag "kubeadm reset --dry-run" is similar to the existing flag for "kubeadm init/join/upgrade" and allows you to see what changes would be applied. ([#107512](https://github.com/kubernetes/kubernetes/pull/107512), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]

- Kubeadm: Added support for additional authentication strategies in `kubeadm join` with discovery/kubeconfig file: client-go authentication plugins (`exec`), `tokenFile`, and `authProvider.` ([#110553](https://github.com/kubernetes/kubernetes/pull/110553), [@tallaxes](https://github.com/tallaxes))

- Kubeadm: graduated the kubeadm specific feature gate `WaitForAllControlPlaneComponents` to GA. The feature gate is was locked to always be enabled and on node initialization kubeadm performed a health check for all control plane components and not only the `kube-apiserver`....

* kubeadm: Fix a bug where `kubeadm join` would wait 5 seconds without doing anything. Now `kubeadm join` executes the tasks immediately. ([#48737](https://github.com/kubernetes/kubernetes/pull/48737), [@mattmoyer](https://github.com/mattmoyer))

- Kubeadm: add `--feature-gates` flag for `kubeadm upgrade node` ([#118316](https://github.com/kubernetes/kubernetes/pull/118316), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]

- Kubeadm: removed the `UnversionedKubeletConfigMap` feature gate. The feature has been GA and locked to enabled since `v1.25`. ([#113448](https://github.com/kubernetes/kubernetes/pull/113448), [@pacoxu](https://github.com/pacoxu))
