Features for this release were tracked via the use of the [kubernetes/features](https://github.com/kubernetes/features) issues repo. Each Feature issue is owned by a Special Interest Group from [kubernetes/community](https://github.com/kubernetes/community)

## Kubefed

- Replace `go-bindata` with `//go:embed`. ([#99829](https://github.com/kubernetes/kubernetes/pull/99829), [@palnabarun](https://github.com/palnabarun))
- The `DynamicFakeClient` now exposes its tracker via a `Tracker()` function. ([#100085](https://github.com/kubernetes/kubernetes/pull/100085), [@markusthoemmes](https://github.com/markusthoemmes))

- When feature gate `JobTrackingWithFinalizers` is enabled:
  - Limit the number of Pods tracked in a single Job sync to avoid starvation of small Jobs.
  - The metric `job_pod_finished_total` counts the number of finished Pods tracked by the Job controller. ([#105197](https://github.com/kubernetes/kubernetes/pull/105197), [@alculquicondor](https://github.com/alculquicondor))

  // A collection of filters that must match each object tracked by a quota.
  // If not specified, the quota matches all objects.
  // +optional
  repeated string scopes = 2;

  // scopeSelector is also a collection of filters like scopes that must match each object tracked by a quota
  // but expressed using ScopeSelectorOperator in combination with possible values.

### Feature

- A client-go metric, rest_client_exec_plugin_call_total, has been added to track total calls to client-go credential plugins. ([#98892](https://github.com/kubernetes/kubernetes/pull/98892), [@ankeesler](https://github.com/ankeesler)) [SIG API Machinery, Auth, Cluster Lifecycle and Instrumentation]

- 'Graduated `JobTrackingWithFinalizers` to stable.
  Jobs created before the feature was enabled are still tracked without finalizers.
  Jobs tracked with finalizers have the annotation batch.kubernetes.io/job-tracking.
  If the annotation is present and the user attempts to remove it, the control plane adds it back.

- Trace output in apiserver logs is more organized and comprehensive. Traces are nested, and for all non-long running request endpoints, the entire filter chain is instrumented (e.g. authentication check is included). ([#88936](https://github.com/kubernetes/kubernetes/pull/88936), [@jpbet...

## Notable Features

- Enhance Azure cloud provider code to support both AAD and ADFS authentication. ([#80841](https://github.com/kubernetes/kubernetes/pull/80841), [@rjaini](https://github.com/rjaini))
- kubeadm: implement support for concurrent add/remove of stacked etcd members ([#79677](https://github.com/kubernetes/kubernetes/pull/79677), [@neolit123](https://github.com/neolit123))

* APIserver backed by etcdv3 exports metric shows number of resources per kind. ([#59757](https://github.com/kubernetes/kubernetes/pull/59757), [@gmarek](https://github.com/gmarek))
