### Feature

- Added 3 new metrics for monitoring async API calls in the scheduler when the `SchedulerAsyncAPICalls` feature gate was enabled:
    - `scheduler_async_api_call_execution_total`: tracks executed API calls by call type and result (success/error)
    - `scheduler_async_api_call_duration_seconds`: histogram of API call execution duration by call type and result

- Known issue: fixed that the PreEnqueue plugins aren't executed for Pods proceeding to activeQ through backoffQ. ([#117194](https://github.com/kubernetes/kubernetes/pull/117194), [@sanposhiho](https://github.com/sanposhiho)) [SIG Release and Scheduling]

- Kubeadm will cleanup the stale data on best effort basis. Stale data will be removed when each reset phase are executed, default etcd data directory will be cleanup when the `remove-etcd-member` phase are executed. ([#110972](https://github.com/kubernetes/kubernetes/pull/110972), [@chendave](https://github.com/chendave)) [SIG Cluster Lifecycle]

- Replace framework.Failf with ExpectNoError ([#91811](https://github.com/kubernetes/kubernetes/pull/91811), [@lixiaobing1](https://github.com/lixiaobing1)) [SIG Instrumentation, Storage and Testing]
- Scheduler PreScore plugins are not executed if there is one filtered node or less. ([#89370](https://github.com/kubernetes/kubernetes/pull/89370), [@ahg-g](https://github.com/ahg-g)) [SIG Scheduling]

- Specifying the KUBE_TEST_REPO environment variable when e2e tests are executed will instruct the test infrastructure to load that image from a location within the specified repo, using a predefined pattern.

Kubeadm: Expose the `kubeadm join` workflow as phases

- The `kubeadm join` command can now be used in phases. Similar to the work that was done for `kubeadm init` in 1.13, in 1.14 the `join` phases can be now executed step-by-step/selectively using the `kubeadm join phase` sub-command. This makes it possible to further customize the workflow of joining nodes to the cluster.
kubernetes/kubeadm: [#1204](https://github.com/kubernetes/kubeadm/issues/1204)

  * Add generic Toleration for NoExecute Taints to NodeProblemDetector, so that NPD can be scheduled to nodes with NoExecute taints by default. ([#45883](https://github.com/kubernetes/kubernetes/pull/45883), [@gmarek](https://github.com/gmarek))

## Changelog since v1.10.2

### Other notable changes

* Use inline func to ensure unlock is executed ([#61644](https://github.com/kubernetes/kubernetes/pull/61644), [@resouer](https://github.com/resouer))

* kubeadm: Fix a bug where `kubeadm join` would wait 5 seconds without doing anything. Now `kubeadm join` executes the tasks immediately. ([#48737](https://github.com/kubernetes/kubernetes/pull/48737), [@mattmoyer](https://github.com/mattmoyer))
