- Fixed the problem of validation error when specifying resource requirements at the container level for a resource not supported at the pod level. It implicitly interpreted the pod-level value as 0.

- kubeadm now works better when not connected to the Internet. In addition,  common kubeadm commands will now work without an available networking interface. ([#67397](https://github.com/kubernetes/kubernetes/pull/67397), [@neolit123](https://github.com/neolit123))

  
  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. ([#125197](https://github.com/kubernetes/kubernetes/pull/125197), [@gabesaba](https://github.com/gabesaba))

- The resource version option, when passed to a list call, is now consistently interpreted as the minimum allowed resource version.  Previously when listing resources that had the watch cache disabled clients could retrieve a snapshot at that exact resource version.  If the client requests a resource version newer than the current state,...

* 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.
