- Changed the error message of `kubectl rollout restart` when subsequent `kubectl rollout restart` commands are executed within a second ([#113040](https://github.com/kubernetes/kubernetes/pull/113040), [@ardaguclu](https://github.com/ardaguclu))

- Added label selector flag to all `kubectl rollout` commands. ([#99758](https://github.com/kubernetes/kubernetes/pull/99758), [@aramperes](https://github.com/aramperes))
- Added more message for no PodSandbox container. ([#107116](https://github.com/kubernetes/kubernetes/pull/107116), [@yxxhero](https://github.com/yxxhero))

- `--log-flush-frequency` had no effect in several commands or was missing. Help and warning texts were not always using the right format for a command (`add_dir_header` instead of `add-dir-header`). Fixing this included cleaning up flag handling in component-base/logs: that package no longer adds flags to the global flag sets. Commands which want the klog and `--log-flush-frequency` flags must explicitly call `logs.AddFlags`; the new `cli.Run`...

- Action-required: kubeadm: remove the deprecated feature --experimental-kustomize from kubeadm commands. The feature was replaced with --experimental-patches...

* Add support for running clusters on GCI ([#24893](https://github.com/kubernetes/kubernetes/pull/24893), [@andyzheng0831](https://github.com/andyzheng0831))
* Trusty: Add retry in curl commands ([#24749](https://github.com/kubernetes/kubernetes/pull/24749), [@andyzheng0831](https://github.com/andyzheng0831))



# v1.2.3

### CLI Improvements

- Added `kubeadm upgrade node`. This command can be used to upgrade both secondary control-plane nodes and worker nodes. The `kubeadm upgrade node config` and `kubeadm upgrade node experimental-control-plane` commands are now deprecated. ([#78408](https://github.com/kubernetes/kubernetes/pull/78408), [@fabriziopandini](https://github.com/fabriziopandini))

- Fixed a bug where executing a kubectl command with a jsonpath output expression that has a nested range would ignore expressions following the nested range. ([#88464](https://github.com/kubernetes/kubernetes/pull/88464), [@brianpursley](https://github.com/brianpursley)) [SIG API Machinery]

* Caching added to the OIDC client auth plugin to fix races and reduce the time kubectl commands using this plugin take by several seconds. ([#38167](https://github.com/kubernetes/kubernetes/pull/38167), [@ericchiang](https://github.com/ericchiang))

- Kubeadm: remove the deprecated command `kubeadm config view`. A replacement for this command is `kubectl get cm -n kube-system kubeadm-config -o=jsonpath="{.data.ClusterConfiguration}"` ([#102071](https://github.com/kubernetes/kubernetes/pull/102071), [@neolit123](https://github.com/neolit123))
