- Kubeadm: get k8s CI version markers from k8s infra bucket ([#98836](https://github.com/kubernetes/kubernetes/pull/98836), [@hasheddan](https://github.com/hasheddan)) [SIG Cluster Lifecycle and Release]

* When using client or server certificate rotation, the Kubelet will no longer wait until the initial rotation succeeds or fails before starting static pods.  This makes running self-hosted masters with rotation more predictable. ([#58930](https://github.com/kubernetes/kubernetes/pull/58930), [@smarterclayton](https://github.com/smarterclayton))

DockerValidor and ServiceCheck for the `docker` service from kubeadm preflight. Docker is no longer special cased during host validation and ideally this task should be done in the now external cri-dockerd project where the importance of the compatibility matters. Use `crictl` for all communication with CRI sockets for actions like pulling images and obtaining a list of running containers instead of using the docker CLI in the case of Docker.
