* Improve internal typing, declare `Optional` parameters. PR [#1731](https://github.com/tiangolo/fastapi/pull/1731) by [@MashhadiNima](https://github.com/MashhadiNima).
* Add external link [Deploy FastAPI on Azure App Service](https://www.tutlinks.com/deploy-fastapi-on-azure/) to docs. PR [#1726](https://github.com/tiangolo/fastapi/pull/1726) by [@windson](https://github.com/windson).

* `metrics-server` is now the recommended way to provide the resource
  metrics API. Deploy `metrics-server` as an add-on in the same way that you deploy Heapster.

##### Cluster Autoscaler

* Cluster autoscaler is now GA
* Cluster support size is increased to 1000 nodes
* Respect graceful pod termination of up to 10 minutes

* kubeadm now accepts `--apiserver-extra-args`, `--controller-manager-extra-args` and `--scheduler-extra-args`, making it possible to override / specify additional flags for control plane components. One good example is to deploy Kubernetes with a different admission-control flag on API server.

- CoreDNS is only officially supported on Linux at this time.  As such, when kubeadm is used to deploy this component into your kubernetes cluster, it will be restricted (using `nodeSelectors`) to run only on nodes with that operating system. This ensures that in clusters which include Windows nodes, the scheduler will not ever attempt to place CoreDNS...

- Fixed computing backoff delay when using Job pod failure policy, by including in the backoff delay calculation pod failures ignored from the backoffLimit counter. ([#119434](https://github.com/kubernetes/kubernetes/pull/119434), [@mimowo](https://github.com/mimowo))

features and stability work required for bootstrapping production clusters efficiently. kubeadm has promoted high availability (HA) capability to beta, allowing users to use the familiar `kubeadm init` and `kubeadm join` commands to [configure and deploy an HA control plane](https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/high-availability/). An entire new test suite has been created specifically for ensuring these features will stay stable over time.
