- Secure master -> node communication ([#11816](https://github.com/kubernetes/kubernetes/issues/11816))
- upgrading master doesn't upgrade kubectl ([#32538](https://github.com/kubernetes/kubernetes/issues/32538))
- Specific error message on failed rolling update issued by older kubectl against 1.4 master ([#32751](https://github.com/kubernetes/kubernetes/issues/32751))

- **Cluster Ops**
  - [alpha] Added ability to create/remove clusters w/highly available (replicated) masters on GCE using kube-up/kube-down scripts. ([docs](http://kubernetes.io/docs/admin/ha-master-gce/)) ([kubernetes/features#48](https://github.com/kubernetes/enhancements/issues/48))

- Changed kuberc configuration schema. Two new optional fields added to kuberc configuration, `credPluginPolicy` and `credPluginAllowlist`. This is documented in [KEP-3104](https://github.com/kubernetes/enhancements/blob/master/keps/sig-cli/3104-introduce-kuberc/README.md#allowlist-design-details) and documentation is added to the website by [kubernetes/website#52877](https://github.com/kubernetes/website/pull/52877) ([#134870](https://github.com/kubernetes/kubernetes/pull/134870),...
