- API server's deprecated `--experimental-encryption-provider-config` flag is now removed. Adapt your machinery to use the `--encryption-provider-config` flag that is available since v1.13. ([#108423](https://github.com/kubernetes/kubernetes/pull/108423), [@ialidzhikov](https://github.com/ialidzhikov))

- kubeadm now includes the ability to specify certificate encryption and decryption keys for the upload and download certificate phases as part of the new v1beta2 kubeadm config format. ([#77012](https://github.com/kubernetes/kubernetes/pull/77012), [@rosti](https://github.com/rosti))

- Added a new metric `apiserver_encryption_config_controller_automatic_reloads_total` to measure the total number of API server encryption configuration reload successes and failures.  This metric now contains the `status` label with a value that is either `success` or `failure`. Deprecated the metrics `apiserver_encryption_config_controller_automatic_reload_success_total` and `ap...

- KMS Providers will install a healthz check for the status of kms-plugin in kube-apiservers' encryption config. ([#78540](https://github.com/kubernetes/kubernetes/pull/78540), [@immutableT](https://github.com/immutableT))

- Included an additional resource labeltransformation in on_operations_total metric which could be used for resource specific validations for example handling of encryption config by the apiserver.

* AWS now checks for validity of ecryption key when creating encrypted volumes. Dynamic provisioning of encrypted volume may get slower due to these checks. ([#65223](https://github.com/kubernetes/kubernetes/pull/65223), [@jsafrane](https://github.com/jsafrane))
