Function   Behavior

print      prints all arguments; formatting of arguments is implementation-specific
println    like print but prints spaces between arguments and a newline at the end

accept arbitrary argument types, but printing of boolean, numeric, and string

- kubectl: `--use-openapi-print-columns` has been deprecated in favor of `--server-print`, and will be removed in a future version. ([#65601](https://github.com/kubernetes/kubernetes/pull/65601), [@liggitt](https://github.com/liggitt))

  * Fix kubectl get -f <file> -o <nondefault printer> so it prints all items in the file ([#39038](https://github.com/kubernetes/kubernetes/pull/39038), [@ncdc](https://github.com/ncdc))
  * kubectl describe no longer prints the last-applied-configuration annotation for secrets. ([#34664](https://github.com/kubernetes/kubernetes/pull/34664), [@ymqytw](https://github.com/ymqytw))

Kubeadm: improve the strict parsing of user YAML/JSON configuration files. Next to printing warnings for unknown and duplicate fields (current state), also print warnings for fields with incorrect case sensitivity - e.g. `controlPlaneEndpoint` (valid), `ControlPlaneEndpoint` (invalid). Instead of only printing warnings during `init` and `join` also print warnings when downloading the ClusterConfiguration, KubeletConfiguration or KubeProxyConfiguration objects from the cluster. This can be useful if the...

* kubectl: fixes a regression with --use-openapi-print-columns that would not print object contents ([#65600](https://github.com/kubernetes/kubernetes/pull/65600), [@liggitt](https://github.com/liggitt))

* remove iSCSI volume storage cleartext secrets in logs ([#81215](https://github.com/kubernetes/kubernetes/pull/81215), [@zouyee](https://github.com/zouyee))
* Fix a bug in server printer that could cause kube-apiserver to panic. ([#79349](https://github.com/kubernetes/kubernetes/pull/79349), [@roycaihw](https://github.com/roycaihw))

- If a bad flag is supplied to a kubectl command, only a tip to run `--help` is printed, instead of the usage menu.  Usage menu is printed upon running `kubectl command --help`. ([#82423](https://github.com/kubernetes/kubernetes/pull/82423), [@sallyom](https://github.com/sallyom))

- `kubectl rollout restart` now works for DaemonSets and StatefulSets. ([#77423](https://github.com/kubernetes/kubernetes/pull/77423), [@apelisse](https://github.com/apelisse))
- `kubectl get --watch=true` now prints custom resource definitions with custom print columns. ([#76161](https://github.com/kubernetes/kubernetes/pull/76161), [@liggitt](https://github.com/liggitt))

  - The DynamicKubeletConfig feature gate is deprecated. The functionality is still accessible by using the kubeadm alpha kubelet enable-dynamic command.
  - The command `kubeadm config print-defaults` is deprecated in favor of `kubeadm config print init-defaults` and `kubeadm config print join-defaults` ([#69617](https://github.com/kubernetes/kubernetes/pull/69617), [@rosti](https://github.com/rosti))

- Fixed kubelet logging to properly respect verbosity levels. Previously, some debug/info messages using V().Error() would always be printed regardless of the configured log verbosity.
