### Failing Test

- Fixes the `should receive events on concurrent watches in same order` conformance test to work properly on clusters that auto-create additional configmaps in namespaces ([#101950](https://github.com/kubernetes/kubernetes/pull/101950), [@liggitt](https://github.com/liggitt)) [SIG API Machinery and Testing]

### Bug or Regression

- Existing InTree AzureFile PVs which don't have a secret namespace defined will now work properly after enabling CSI migration - the namespace will be obtained from ClaimRef. ([#108000](https://github.com/kubernetes/kubernetes/pull/108000), [@RomanBednar](https://github.com/RomanBednar)) [SIG Cloud Provider and Storage]

## Known Issues

### CPU and Memory manager are not working correctly for Guaranteed Pods with multiple containers

This feature adds [a new option to PriorityClasses](https://github.com/kubernetes/enhancements/issues/902),
which can enable or disable pod preemption.

### Storage Plugin Migration

There is work under way to [migrate the internals of in-tree storage plugins](https://github.com/kubernetes/enhancements/issues/625) to call out to CSI Plugins,
while maintaining the original API.

- kubeadm: fix the bug that `--cri-socket` flag does not work for `kubeadm reset` ([#79498](https://github.com/kubernetes/kubernetes/pull/79498), [@SataQiu](https://github.com/SataQiu))

- Revert kubelet prober metrics `pod` tag to include actual pod name ([#118549](https://github.com/kubernetes/kubernetes/pull/118549), [@a7i](https://github.com/a7i)) [SIG Node]
- Update kube-apiserver's priority & fairness work estimator such that 'max seats' is MIN(0.15 x nominalCL, nominalCL / handSize)

* kubeadm creates RBAC-enabled clusters. This means that some add-ons which worked previously won't work without having their YAML configuration updated. Please see each vendor's own documentation to check that the add-ons you are using will work with Kubernetes 1.6.

        * `{WorkQueueName}_work_duration`
        * `{WorkQueueName}_unfinished_work_seconds`
        * `{WorkQueueName}_longest_running_processor_microseconds`
        * `{WorkQueueName}_retries`
    * Please convert to the following metrics:
        * `workqueue_depth`
        * `workqueue_adds_total`
        * `workqueue_queue_latency_seconds`
        * `workqueue_work_duration_seconds`

* Bugfix: OpenAPI models may not get group-version-kind extension if kubernetes is vendored in another project (e.g. minikube). Kubectl 1.8 needs this extension to work with those projects. ([#53152](https://github.com/kubernetes/kubernetes/pull/53152), [@mbohlool](https://github.com/mbohlool))
