### Bug or Regression

- Fix Topology Aware Hints not working when the `topology.kubernetes.io/zone` label is added after Node creation

- Kubeadm: fix the bug that 'kubeadm upgrade' hangs in single node cluster ([#88434](https://github.com/kubernetes/kubernetes/pull/88434), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]

* kubelet to master communication when doing node status updates now has a timeout to prevent indefinite hangs ([#52176](https://github.com/kubernetes/kubernetes/pull/52176), [@liggitt](https://github.com/liggitt))

As of Kuberenetes v1.19, Kubernetes container images are stored on a community-controlled storage bucket, 
located at `{asia,eu,us}.gcr.io/k8s-artifacts-prod`. The `k8s.gcr.io` vanity domain has been updated 
to this new bucket. This brings production artifacts under community control.
