* The `--bootstrap-kubeconfig` argument to Kubelet previously created the first bootstrap client credentials in the certificates directory as `kubelet-client.key` and `kubelet-client.crt`.  Subsequent certificates created by cert rotation were created in a combined PEM file that was atomically rotated as `kubelet-client-DATE.pem` in that directory, which meant clients relying on the `node.kubeconfig` generated...

    * PV creation Logs:

* Added new flag to `kubeadm init`: --node-name, that lets you specify the name of the Node object that will be created ([#48594](https://github.com/kubernetes/kubernetes/pull/48594), [@GheRivero](https://github.com/GheRivero))
* Added new flag to `kubeadm join`: --node-name, that lets you specify the name of the Node object that's gonna be created ([#48538](https://github.com/kubernetes/kubernetes/pull/48538), [@GheRivero](https://github.com/GheRivero))

  * You can find the PodSpec tolerations that were created as annotations (if any) in a controller definition by doing `kubectl get <controller kind> <controller name> -o yaml` and looking for the "Annotation" section with the annotation...

### AWS

* Add AWS cloud provider option to use an assumed IAM role. For example, this allows running Controller Manager in a account separate from the worker nodes, but still allows all resources created to interact with the workers. ELBs created would be in the same account as the worker nodes for instance.([#59668](https://github.com/kubernetes/kubernetes/pull/59668), [@brycecarman](https://github.com/brycecarman))

#### kubeadm

* [beta] A new `upgrade` subcommand allows you to automatically upgrade a self-hosted cluster created with kubeadm. ([#296](https://github.com/kubernetes/enhancements/issues/296), [@luxas](https://github.com/luxas))

- Fix a bug in cronjob controller where already created jobs may be missing from the status. ([#120649](https://github.com/kubernetes/kubernetes/pull/120649), [@andrewsykim](https://github.com/andrewsykim)) [SIG Apps]

  - Certificates created with kubeadm now have improved uniqueness of Distinguished Name fields.
- HA improvements:
  - `kubeadm join --experimental-control-plane` can now be used to join control plane instances to an existing cluster.
  - `kubeadm upgrade node experimental-control-plane` can now be used for upgrading secondary control plane instances created with `kubeadm join --experimental-control-plane`.
