Kubernetes will keep allowing leading zeros on IPv4 address to not break the compatibility.
  IMPORTANT: Kubernetes interprets leading zeros on IPv4 addresses as decimal, users must not rely on parser alignment to not being impacted by the associated security advisory:

* Refactor factory_test.go to use a fake k8s client. ([#69412](https://github.com/kubernetes/kubernetes/pull/69412), [@tossmilestone](https://github.com/tossmilestone))
* kubeadm: fix a case where fetching a kubernetesVersion from the internet still happened even if some commands don't need it. ([#69645](https://github.com/kubernetes/kubernetes/pull/69645), [@neolit123](https://github.com/neolit123))

- Kubeadm: now sets the host `OS` environment variables when executing `crictl` during image pulls. This fixed a bug where `*PROXY` environment variables did not affect `crictl` internet connectivity.

  For developers of out-of-tree PostFilter plugins, note that the semantics of NodeToStatusMap are changing: A node with an absent value in the NodeToStatusMap should be interpreted as having an UnschedulableAndUnresolvable status.
