  "Cluster" routes internal traffic to a Service to all endpoints.
  "Local" routes traffic to node-local endpoints only, and traffic is dropped if no node-local endpoints are ready.

- Fix an error when using external etcd but storing etcd certificates in the same folder with the same name used by kubeadm for local etcd certificates; for an older version of kubeadm, the workaround is to avoid file name used by kubeadm for local etcd.

Durable Local Storage Management is Now GA ([#121](https://github.com/kubernetes/enhancements/issues/121#issuecomment-457396290))

- Makes locally attached (non-network attached) storage available as a persistent volume source.
- Allows users to take advantage of the typically cheaper and improved performance of persistent local storage

supported on Windows](https://github.com/kubernetes/kubernetes/pull/60275).) [Local Ephemeral Storage Capacity Isolation](https://github.com/kubernetes/enhancements/issues/361) makes it possible to set requests and limits on ephemeral local storage resources. In addition, you can now create [Local Persistent Storage](https://github.com/kubernetes/enhancements/issues/121), which enables PersistentVolumes to be created with locally attached disks, and not just network volumes.

On the Persistent...

### **Storage**
#### Local Storage
* [alpha] This feature adds capacity isolation support for local storage at node, container, and volume levels. See updated [Reserve Compute Resources for System Daemons](https://kubernetes.io/docs/tasks/administer-cluster/reserve-compute-resources/) documentation.

#### Lifecycle

- Support for deprecated old kubeadm v1alpha3 config has been totally removed. ([#75179](https://github.com/kubernetes/kubernetes/pull/75179), [@rosti](https://github.com/rosti))
- kube-up.sh no longer supports "centos" and "local" providers. ([#76711](https://github.com/kubernetes/kubernetes/pull/76711), [@dims](https://github.com/dims))
