* Add secretbox and AES-CBC encryption modes to at rest encryption. AES-CBC is considered superior to AES-GCM because it is resistant to nonce-reuse attacks, and secretbox uses Poly1305 and XSalsa20. ([#46916](https://github.com/kubernetes/kubernetes/pull/46916), [@smarterclayton](https://github.com/smarterclayton))

* Bug fixes:

* Bump up addon kube-dns to v20 for graceful termination ([#33774](https://github.com/kubernetes/kubernetes/pull/33774), [@MrHohn](https://github.com/MrHohn))
* Creating LoadBalancer Service with "None" ClusterIP is no longer possible ([#33274](https://github.com/kubernetes/kubernetes/pull/33274), [@nebril](https://github.com/nebril))

* Default mount propagation has changed from `HostToContainer` ("rslave" in Linux terminology), as it was in 1.10, to `None` ("private") to match the behavior in 1.9 and earlier releases; `HostToContainer` as a default caused regressions in some pods. If you are relying on this behavior you will need to set it explicitly. ([#62462](https://github.com/kubernetes/kubernetes/pull/62462),...
