###  Introduced KMS v2

Introduce KMS v2alpha1 API to add performance, rotation, and observability improvements. Encrypt data at rest (ie Kubernetes `Secrets`) with DEK using AES-GCM instead of AES-CBC for kms data encryption. No user action is required. Reads with AES-GCM and AES-CBC will continue to be allowed. See the guide [Using a KMS provider for data encryption](https://kubernetes.io/docs/tasks/administer-cluster/kms-provider/) for more information.
