- API emulation versioning honors cohabitating resources ([#127239](https://github.com/kubernetes/kubernetes/pull/127239), [@xuzhenglun](https://github.com/xuzhenglun)) [SIG API Machinery]
- Apiserver repair controller is resilient to etcd errors during bootstrap and retries during 30 seconds before failing. ([#126671](https://github.com/kubernetes/kubernetes/pull/126671), [@fusida](https://github.com/fusida)) [SIG Network]

- Kubeadm: added retry to all the calls to the etcd API so kubeadm will be more resilient to network glitches ([#85201](https://github.com/kubernetes/kubernetes/pull/85201), [@fabriziopandini](https://github.com/fabriziopandini))

    * faster handoff when a leader-elected process is gracefully terminated.
* Make volume binder resilient to races between main schedule loop and async binding operation  ([#72045](https://github.com/kubernetes/kubernetes/pull/72045), [@cofyc](https://github.com/cofyc))

- Kubeadm: Add retries for kubeadm join / UpdateStatus to make update status more resilient by adding a retry loop to this operation ([#91952](https://github.com/kubernetes/kubernetes/pull/91952), [@xlgao-zju](https://github.com/xlgao-zju)) [SIG Cluster Lifecycle]
