- Fixes high CPU usage in kubectl drain ([#95260](https://github.com/kubernetes/kubernetes/pull/95260), [@amandahla](https://github.com/amandahla)) [SIG CLI]

### kubectl (CLI)
* `kubectl create role` and  `kubectl create clusterrole`  invocations must be updated to specify multiple resource names as repeated  `--resource-name` arguments instead of comma-separated arguments to a single `--resource-name` argument. E.g. `--resource-name=x,y` must become `--resource-name x --resource-name y` ([#44950](https://github.com/kubernetes/kubernetes/pull/44950), [@xilabao](https://github.com/xilabao))

* Running `kubectl taint` (alpha in 1.5) against a 1.5 server requires a kubectl version of 1.5
* Running `kubectl create secret` no longer accepts passing multiple values to a single --from-literal flag using comma separation
  * Update command invocations to pass separate --from-literal flags for each value

// PodPortForwardOptions is the query options to a Pod's port forward call
// when using WebSockets.
// The `port` query parameter must specify the port or
// ports (comma separated) to forward over.
// Port forwarding over SPDY does not use these options. It requires the port
// to be passed in the `port` header as part of request.

- kubeadm: use the `--pod-network-cidr` flag to init or use the podSubnet field in the kubeadm config to pass a comma separated list of pod CIDRs. ([#79033](https://github.com/kubernetes/kubernetes/pull/79033), [@Arvinderpal](https://github.com/Arvinderpal))

- The `CloudDualStackNodeIPs` feature is now `beta`, meaning that when using
  an external cloud provider that has been updated to support the feature,
  you can pass comma-separated dual-stack `--node-ips` to `kubelet` and have
  the cloud provider take both IPs into account. ([#120275](https://github.com/kubernetes/kubernetes/pull/120275), [@danwinship](https://github.com/danwinship))

expression and the type declaration is parsed as an array type declaration.
To resolve the ambiguity, embed the constraint in an
<a href="#Interface_types">interface</a> or use a trailing comma:
</p>

<pre>
type T[P interface{*C}] …
type T[P *C,] …
</pre>

<p>
Type parameters may also be declared by the receiver specification

the email address of the service account directly. (This is a breaking change if the numeric uniqueIDs of the Google service accounts were being used in RBAC role bindings. The behavior can be overridden by explicitly specifying the scope values as comma-separated string in the "users[*].config.scopes" field in the KUBECONFIG file.) This way, users can now  set a Google Service Account JSON key in the  GOOGLE_APPLICATION_CREDENTIALS environment variable, craft a kubeconfig file with GKE master IP+CA...

* kubelet's `--cni-bin-dir` option now accepts multiple comma-separated CNI binary directory paths, which are searched for CNI plugins in the given order. ([#58714](https://github.com/kubernetes/kubernetes/pull/58714), [@dcbw](https://github.com/dcbw))
