- Kubeadm: fixed a bug where the path of the manifest can not be specified when `kubeadm upgrade diff` specified a config file, and the `--api-server-manifest`, `--controller-manager-manifest` and `--scheduler-manifest` flags of `kubeadm upgrade diff` are marked as deprecated and will be removed in a future release. ([#125779](https://gi...

of v1.25, the PodSecurity `restricted` level no longer requires pods that set .spec.os.name="windows" to also set Linux-specific securityContext fields. If a 1.25+ cluster has unsupported [out-of-skew](https://kubernetes.io/releases/version-skew-policy/#kubelet) nodes prior to v1.23 and wants to ensure namespaces enforcing the `restricted` policy continue to require Linux-specific securityContext fields on all pods, ensure a version of the `restricted` prior to v1.25 is selected by labeling the namespace...

- When `SchedulerQueueingHint` is enabled,
  the scheduler's in-tree plugins now subscribe to specific node events to decide whether to requeue Pods.
  This allows the scheduler to handle cluster events faster with less memory.

  Specific node events include updates to taints, tolerations or allocatable.

- Kubeadm: the `kubelet-finalize` phase of `kubeadm init` no longer requires the kubelet kubeconfig to have a specific authinfo. ([#123171](https://github.com/kubernetes/kubernetes/pull/123171), [@vrutkovs](https://github.com/vrutkovs))

dropin, a structured configuration file for the kubelet is used, and is expected to be present in `/var/lib/kubelet/config.yaml`. For runtime-detected, instance-specific configuration values, a environment file with dynamically-generated flags at `kubeadm init` or `kubeadm join` run time is used. Finally, if you want to override something specific for the kubelet that can't be done via the kubeadm Configuration file (which is preferred), you might add flags to the `KUBELET_EXTRA_ARGS` environment variable...
