### Removing deprecated flags in kubeadm

kubernetes/enhancements: [#121](https://github.com/kubernetes/enhancements/issues/121#issuecomment-457396290) [[kep](https://github.com/kubernetes/enhancements/blob/master/keps/sig-storage/121-local-persistent-volumes/README.md)]

Pid Limiting is Graduating to Beta ([#757](https://github.com/kubernetes/enhancements/issues/757))

- Prevents a pod from starving pid resource
- Ability to isolate pid resources pod-to-pod and node-to-pod

- Fixed a bug that caused a DaemonSet rolling update to hang when its pod gets stuck at terminating.  ([#77773](https://github.com/kubernetes/kubernetes/pull/77773), [@DaiHao](https://github.com/DaiHao))
- Route controller now respects rate limiting to the cloud provider on deletion; previously it was only for create. ([#78581](https://github.com/kubernetes/kubernetes/pull/78581), [@andrewsykim](https://github.com/andrewsykim))

* vSphere cloud provider: Fix volume detach on node failure. ([#45569](https://github.com/kubernetes/kubernetes/pull/45569), [@divyenpatel](https://github.com/divyenpatel))
* Job controller: Retry with rate-limiting if a Pod create/delete operation fails. ([#45870](https://github.com/kubernetes/kubernetes/pull/45870), [@tacy](https://github.com/tacy))

- Alpha support for field selectors on custom resources has been added. With the `CustomResourceFieldSelectors` feature gate enabled, the CustomResourceDefinition API now allows specifying `selectableFields`. Listing a field there enables filtering custom resources for that CustomResourceDefinition in list or watch requests. ([#122717](https://github.com/kubernetes/kubernetes/pull/122717), [@jpbetz](https://github.com/jpbetz))

    * Don't watch .mount cgroups to reduce number of inotify watches
    * Fix NVML initialization race condition
    * Fix brtfs disk metrics when using a subdirectory of a subvolume
* Change Azure ARM Rate limiting error message. ([#65292](https://github.com/kubernetes/kubernetes/pull/65292), [@wgliang](https://github.com/wgliang))

- Kubelet: security of dynamic resource allocation was enhanced by limiting node access to those objects that are needed on the node. ([#116254](https://github.com/kubernetes/kubernetes/pull/116254), [@pohly](https://github.com/pohly)) [SIG Auth and Testing]

When that form is used, the variable is declared at the end of the
TypeSwitchCase in the <a href="#Blocks">implicit block</a> of each clause.
In clauses with a case listing exactly one type, the variable
has that type; otherwise, the variable has the type of the expression
in the TypeSwitchGuard.

<p>
Instead of a type, a case may use the predeclared identifier
