Kubernetes 1.7 is a milestone release that adds security, stateful application, and extensibility features motivated by widespread production use of Kubernetes.

Security enhancements in this release include encrypted secrets (alpha), network policy for pod-to-pod communication, the node authorizer to limit Kubelet access to API resources, and Kubelet client / server TLS certificate rotation (alpha).

* Change Azure ARM Rate limiting error message. ([#65292](https://github.com/kubernetes/kubernetes/pull/65292), [@wgliang](https://github.com/wgliang))
* 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))

- In `kube-apiserver`, custom resources can now be specified in the `--encryption-provider-config` file and can be encrypted in etcd. ([#113015](https://github.com/kubernetes/kubernetes/pull/113015), [@ritazh](https://github.com/ritazh))

 - Encrypted data with DEK using AES-GCM instead of AES-CBC for kms data encryption. No user action required. Reads with AES-GCM and AES-CBC will continue to be allowed. ([#111119](https://github.com/kubernetes/kubernetes/pull/111119), [@aramase](https://github.com/aramase))...

### Bug or Regression

- Fixed a bug where clusters that use KMS v1 with skewed API servers on versions v1.24 and v1.25 would see internal errors when attempting to read encrypted data via the v1.24 API servers.
