### Failing Test

- Added mock framework support for unit tests for Windows in `kubeproxy`. ([#120105](https://github.com/kubernetes/kubernetes/pull/120105), [@princepereira](https://github.com/princepereira))

- Kube-apiserver: requests to node, Service, and Pod `/proxy` subresources with no additional URL path now only automatically redirect GET and HEAD requests. ([#95128](https://github.com/kubernetes/kubernetes/pull/95128), [@Riaankl](https://github.com/Riaankl))

reclaim policy has been deprecated. Users should use dynamic provisioning instead. ([#59063](https://github.com/kubernetes/kubernetes/pull/59063), [@ayushpateria](https://github.com/ayushpateria))

* kube-apiserver flag --tls-ca-file has had no effect for some time.  It is now deprecated and slated for removal in 1.11.  If you are specifying this flag, you must remove it from your launch config before upgrading to 1.11. ([#58968](https://github.com/kubernetes/kubernetes/pull/58968), [@...

- Recording timing traces had a race condition. Impact in practice was probably low. ([#117139](https://github.com/kubernetes/kubernetes/pull/117139), [@pohly](https://github.com/pohly)) [SIG API Machinery, Architecture, Auth, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation,...

* scheduler: Fix issue were a new pod with affinity gets stuck at `creating` because the node had been deleted but the pod still exists. ([#56835](https://github.com/kubernetes/kubernetes/pull/56835), [@wenlxie](https://github.com/wenlxie))

### Other (Cleanup or Flake)

- 'Promoted `cronjob_job_creation_skew` metric to stable to follow the cronjob v2 controller,
  the following metrics had their name updated to match metrics API guidelines:

	In Namespaces that previously did not have the "DefaultDeny" annotation, you should delete any existing NetworkPolicy objects. These had no effect in the v1beta1 API, but with v1 semantics they might cause some traffic to be unintentionally blocked.


### Storage

    * Action required: Before upgrading your Kubernetes clusters, double check if you had configured webhooks for cluster-scoped objects (e.g., nodes, persistentVolume), these webhooks will start to take effect. Delete/modify the configs if that's not desirable.

### Other notable changes

### Kustomize Updates in Kubectl

[Kustomize](https://github.com/kubernetes-sigs/kustomize) version in kubectl had a jump from v2.0.3 to [v4.0.5](https://github.com/kubernetes/kubernetes/pull/98946). Kustomize is now treated as a library and future updates will be less sporadic.

### Default Container Annotation

### SIG Storage

Sig Storage graduated two features that had been introduced in previous versions and introduced three new features in an alpha state.
