- Added support for max attach limit for Cinder ([#72980](https://github.com/kubernetes/kubernetes/pull/72980), [@gnufied](https://github.com/gnufied))
- Enabled mTLS encryption between etcd and kube-apiserver in GCE ([#70144](https://github.com/kubernetes/kubernetes/pull/70144), [@wenjiaswe](https://github.com/wenjiaswe))

- Communication between the etcd server and kube-apiserver on master is now overridden to use HTTPS instead of HTTP when mTLS is enabled in GCE. ([#74690](https://github.com/kubernetes/kubernetes/pull/74690), [@wenjiaswe](https://github.com/wenjiaswe))
