- The  command line option  --cri-socket-path of the kubeadm subcommand "kubeadm config images pull" has been renamed to --cri-socket to be consistent with the rest of kubeadm subcommands.

 * Both the unnecessary port specification (`:80`) and the absent trailing slash (`/`) cause URI to
 * bucket the two URLs separately. This harms URI's usefulness in collections. Any application that
 * stores information-per-URL will need to either canonicalize manually, or suffer unnecessary
 * redundancy for such URLs.

 - Kubeadm: the flag `--cri-socket` is no longer allowed in a mixture with the flag `--config`. Please use the kubeadm configuration for setting the CRI socket for a node using `{Init|Join}Configuration.nodeRegistration.criSocket`.

### Production images moved to community control

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.

### KubeSchedulerConfiguration graduates to Beta

  // Verify input, output, and subset of edges in fdef.
  // The subset of edges we verify is a chain between feed1 and output to
  // make sure that the correct output is picked.
  tensorflow::FunctionDef fdef;
  ASSERT_TRUE(GetFunctionDef(func_, &fdef));
  VerifyFDefInputs(fdef, M({{"feed1"}, {"feed2"}}));
  VerifyFDefOutputs(fdef, M({{"test_loop_exit"}}));
  VerifyFDefEdges(fdef,

  This is achieved by reducing the TIME-WAIT state of the connection to 1 second, instead of the defaults 60 seconds. This allows kubelet to free the socket, and free conntrack entry and ephemeral port associated.
