- The scheduling queue didn't notice any extenders' failures, it could miss some cluster events,
  and it could end up Pods rejected by Extenders stuck in unschedulable pod pool in 5min in the worst-case scenario.

* The names generated for ControllerRevision and ReplicaSet are consistent with the GenerateName functionality of the API Server and will not contain "bad words". ([#51538](https://github.com/kubernetes/kubernetes/pull/51538), [@kow3ns](https://github.com/kow3ns))

* The deprecated –mode switch for GCE has been removed.([#61203](https://github.com/kubernetes/kubernetes/pull/61203))

* The word “manifest” has been expunged from the Kubelet API. ([#60314](https://github.com/kubernetes/kubernetes/pull/60314))

publicly-available cAdvisor web UI that the kubelet ran on port 4194 by default is now turned off by default. The flag configuring what port to run this UI on `--cadvisor-port` was deprecated in v1.10. Now the default is `--cadvisor-port=0`, in other words, to not run the web server. If you still need to run cAdvisor, the recommended way to run it is via a DaemonSet. Note that the `--cadvisor-port` will be removed in v1.12 ([#63881](https://github.com/kubernetes/kubernetes/pull/63881), [@luxas](http...

- Remove offensive words from kubectl cluster-info command. ([#95202](https://github.com/kubernetes/kubernetes/pull/95202), [@rikatz](https://github.com/rikatz))

- Kubeadm: apply `second stage` of the plan to migrate kubeadm away from the usage of the word `master` in labels and taints. For new clusters, the label `node-role.kubernetes.io/master` will no longer be added to control plane nodes, only the label `node-role.kubernetes.io/control-plane` will be added. For clusters that are being upgraded to...

- Users can now traverse all the pods that are in the scheduler and waiting in the permit stage through method `IterateOverWaitingPods`. In other words,  all waitingPods in scheduler can be obtained from any profiles. Before this commit, each profile could only obtain `waitingPods` within that profile ([#122946](https://github.com/kubernetes/kubernetes/pull/122946), [@NoicFank](https://github.com/NoicFank))...

- Kubelet no longer watches `ConfigMaps` and `Secrets` for terminated pods, in worst scenario causing it to not be able to send other requests to kube-apiserver ([#74809](https://github.com/kubernetes/kubernetes/pull/74809), [@oxddr](https://github.com/oxddr))
