* Fixes the panic that occurs in the federation controller manager when registering a GKE cluster to the federation. Fixes issue [#30790](https://github.com/kubernetes/kubernetes/pull/30790). ([#30940](https://github.com/kubernetes/kubernetes/pull/30940), [@madhusudancs](https://github.com/madhusudancs))

- Fixed an issue with the `garbagecollection` controller registering duplicate event handlers if discovery requests failed. ([#117992](https://github.com/kubernetes/kubernetes/pull/117992), [@liggitt](https://github.com/liggitt))

            return;
        }

        final JobHelper jobHelper = ComponentUtil.getJobHelper();
        if (!jobHelper.isAvailable(id)) {
            logger.info("Job is unavailable, unregistering: id={}", id);
            jobHelper.unregister(scheduledJob);
            return;
        }

        final JobLog jobLog = new JobLog(scheduledJob);
        final String scriptType = scheduledJob.getScriptType();

  So, if you want to just keep the existing behavior, you can register `ClusterEventWithHint` with no `QueueingHintFn` in it. 

TokenReview](https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.13/#tokenreview-v1-authentication-k8s-io) for the new tokens for improved scoping. Under audit logging, the new alpha-level "dynamic audit configuration" adds support for [dynamically registering webhooks to receive a stream of audit events](https://kubernetes.io/docs/tasks/debug/debug-cluster/audit/#webhook-backend). Finally, we've enhanced secrets protection by graduating [etcd encryption](https://kubernetes.io/docs/tasks/administer-c...

- Improved the efficiency of NodeAdded QueueingHint by registering UpdateNodeTaint event for plugins that have NodeAdded event but don't have UpdateNodeTaint event. This ensures better requeuing efficiency and prevents Pods from being stuck in the unschedulable pod pool.
