- Fixed data race in `kube-scheduler` when preemption races with a Pod update. ([#116395](https://github.com/kubernetes/kubernetes/pull/116395), [@alculquicondor](https://github.com/alculquicondor)) [SIG Scheduling]

- Fixes the bug in NodeUnschedulable that only happens with QHint enabled, 
  which the scheduler might miss some updates for the Pods rejected by NodeUnschedulable plugin and put the Pods in the queue for a longer time than needed. ([#127427](https://github.com/kubernetes/kubernetes/pull/127427), [@sanposhiho](https://github.com/sanposhiho)) [SIG Scheduling]
- Fixes the bug in PodTopologySpread that only happens with QHint enabled, 

- Added a new flag `--append-server-path` to `kubectl proxy` that will automatically append the kube context server path to each request. ([#97350](https://github.com/kubernetes/kubernetes/pull/97350), [@FabianKramm](https://github.com/FabianKramm))

  * Added CIFS PV support for Juju Charms ([#45117](https://github.com/kubernetes/kubernetes/pull/45117), [@chuckbutler](https://github.com/chuckbutler))

  * Fixes juju kubernetes master: 1. Get certs from a dead leader. 2. Append tokens. ([#43620](https://github.com/kubernetes/kubernetes/pull/43620), [@ktsakalozos](https://github.com/ktsakalozos))

* Release the kubelet client certificate rotation as beta. ([#51045](https://github.com/kubernetes/kubernetes/pull/51045), [@jcbsmpsn](https://github.com/jcbsmpsn))
* Adds --append-hash flag to kubectl create configmap/secret, which will append a short hash of the configmap/secret contents to the name during creation. ([#49961](https://github.com/kubernetes/kubernetes/pull/49961), [@mtaufen](https://github.com/mtaufen))

  Before this PR, if PreFilter return `Unschedulable`, it may result in an unexpected abortion in the preemption, 
  which shouldn't happen in the default scheduler, but may happen in schedulers with a custom plugin. ([#119779](https://github.com/kubernetes/kubernetes/pull/119779), [@sanposhiho](https://github.com/sanposhiho)) [SIG Scheduling]

- Improved CRI handling
  - crictl is no longer required in docker-only setups.
  - Better detection of installed CRI.
  - Better output for image pull errors.
- Improved air-gapped and offline support
  - kubeadm now handles air-gapped environments by using the local client version as a fallback.
  - Some kubeadm commands are now allowed to work in a completely offline mode.
- Certificate handling improvements:

- DRA: The scheduler plugin prevented abnormal filter runtimes by timing out after 10 seconds. This was configurable...

- Kubeadm: when using a custom image repository for CoreDNS kubeadm now will append the "coredns"  image name instead of  "coredns/coredns", thus restoring the behaviour existing before the v1.21 release. Users who rely on nested folder for the coredns image should set the "clusterConfiguration.dns.imageRepository" value including...

- Sometimes, the scheduler incorrectly placed a pod in the "unschedulable" queue instead of the "backoff" queue. This happened when some plugin previously declared the pod as "unschedulable" and then in a later attempt encounters some other error. Scheduling of that pod then got delayed by up to five minutes, after which periodic flushing moved the pod back into the "active"...
