kubelet when creating a cluster with "kubeadm init" or when joining control plane nodes with "kubeadm join".  The "kubeadm join" workflow now includes two new experimental phases called "control-plane-join-etcd" and "kubelet-wait-bootstrap" which will be used when the feature gate is enabled. This phases will be marked as non-experimental when ControlPlaneKubeletLocalMode becomes GA. During "kubeadm upgrade" commands, if the feature gate is enabled, modify the "/etc/kubernetes/kubelet.conf " to use...

- Kubernetes is now built using Go 1.25.1 ([#134095](https://github.com/kubernetes/kubernetes/pull/134095),...

- kube-controller-manager
  - The deprecated `--insecure-experimental-approve-all-kubelet-csrs-for-group` flag has been removed.
- kubelet

- Remove the deprecated flag `--experimental-check-node-capabilities-before-mount`. With CSI now GA, there is a better alternative. Remove any use of  `--experimental-check-node-capabilities-before-mount` from your kubelet scripts or manifests. ([#104732](https://github.com/kubernetes/kubernetes/pull/104732), [@mengjiao-liu](https://github.com/mengjiao-liu))...

This behavior is controlled by the `winreadlinkvolume` setting.
For Go 1.23, it defaults to `winreadlinkvolume=1`.
Previous versions default to `winreadlinkvolume=0`.

Go 1.23 enabled the experimental post-quantum key exchange mechanism
X25519Kyber768Draft00 by default. The default can be reverted using the
[`tlskyber` setting](/pkg/crypto/tls/#Config.CurvePreferences).

- The Kubelet's `--experimental-allocatable-ignore-eviction` option is now marked as deprecated. ([#91578](https://github.com/kubernetes/kubernetes/pull/91578), [@knabben](https://github.com/knabben)) [SIG Node]

    Node Allocatable. This will result in a reduction of schedulable capacity in
    clusters post upgrade where kubelet hard eviction has been turned on for
    memory. To opt-out set `--experimental-allocatable-ignore-eviction=true`.
