- Kubeadm: default the kubeadm configuration to the containerd socket (Unix: `unix:///var/run/containerd/containerd.sock`, Windows: `npipe:////./pipe/containerd-containerd`) instead of the one for Docker. If the `Init|JoinConfiguration.nodeRegistration.criSocket` field is empty during cluster creation and multiple sockets are found on the host always throw an error and ask the user to specify...

- Windows runtime endpoints is now switched to `npipe:////./pipe/dockershim` from `tcp://localhost:3735`. ([#69516](https://github.com/kubernetes/kubernetes/pull/69516), [@feiskyer](https://github.com/feiskyer))

- Runtime handler and Windows npipe protocol are not supported yet in crictl v1.11.x. Those features will be supported in crictl [v1.12.0](https://github.com/kubernetes-sigs/cri-tools/releases/tag/v1.12.0), together with Kubernetes v1.12.1.

## Major Themes

- Kubeadm: allow passing the flag `--log-file` if `--config` is passed. If you wish to log to a file you must also pass `--logtostderr=false` or `--alsologtostderr=true`. Alternatively you can pipe to a file using "kubeadm ... | tee ...". ([#101449](https://github.com/kubernetes/kubernetes/pull/101449), [@CaoDonghui123](https://github.com/CaoDonghui123))

- Kubeadm: unhide the "etcd-join" phase of "kubeadm join" to allow on-demand execution of the phase if the ControlPlaneLocalMode feature gate is not enabled ([#135481](https://github.com/kubernetes/kubernetes/pull/135481), [@borovetsav](https://github.com/borovetsav))...
