- kubeadm now deletes the bootstrap-kubelet.conf file after TLS bootstrap
  User relying on bootstrap-kubelet.conf should switch to kubelet.conf that contains node credentials ([#80676](https://github.com/kubernetes/kubernetes/pull/80676), [@fabriziopandini](https://github.com/fabriziopandini))

#### Bug fixes

- Kubelet config file will be backed up to `/etc/kubernetes/tmp/` folder with `kubeadm-kubelet-config` append with a random suffix as the filename ([#114695](https://github.com/kubernetes/kubernetes/pull/114695), [@chendave](https://github.com/chendave)) [SIG Cluster Lifecycle]

- Kubeadm: deprecate the "kubeadm alpha kubelet config enable-dynamic" command. To continue using the feature please defer to the guide for "Dynamic Kubelet Configuration" at k8s.io. ([#92881](https://github.com/kubernetes/kubernetes/pull/92881), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]

## Changelog since v1.8.14

### Action Required

* ACTION REQUIRED: Kubernetes JSON deserializer is now case-sensitive to restore compatibility with pre-1.8 servers. If your config files contains fields with wrong case, the config files will be now invalid. ([#65410](https://github.com/kubernetes/kubernetes/pull/65410), [@nikhita](https://github.com/nikhita))

### Other notable changes

- KMS: added validation for duplicate kms config name when auto reload is enabled. If you enabled automatic reload of encryption configuration with API server flag `--encryption-provider-config-automatic-reload`, ensure all the KMS provider names (v1 and v2) in the encryption configuration...

* kubeadm: remove deprecated kubeadm config print-defaults command ([#71467](https://github.com/kuberne...
