- If all QueueingHintFn return QueueSkip, it puts this pod back to the unschedulable pod pool
  
  Having appropriate QueueingHintFn contributes to reducing useless retries and thus improves the overall scheduler's performance.
  
  **How can I migrate?**
  

 
## Changes by Kind

### Deprecation

- ACTION REQUIRED: `failCgroupV1` will be set to true from 1.35. 
  This means that nodes will not start on a cgroup v1 by default. This puts cgroup v1 into a deprecated state. ([#134298](https://github.com/kubernetes/kubernetes/pull/134298), [@kannon92](https://github.com/kannon92))

- If PreBindPreFlight returns Skip, the scheduler doesn't run the plugin at PreBind.
  If any PreBindPreFlight returns Success, the scheduler puts NominatedNodeName to the pod 

### Windows support improved

- Kubelet now exposes `/debug/flags/v` to allow dynamically setting glog logging level.  For example, to change glog level to 3, you only have to send a PUT request like `curl -X PUT http://127.0.0.1:8080/debug/flags/v -d "3"`. ([#64601](https://github.com/kubernetes/kubernetes/pull/64601), [@hzxuzhonghu](https://github.com/hzxuzhonghu))

### SIG OpenStack

    * Introduce a RuntimeClass v1beta1 API. This new beta API renames `runtimeHandler` to `handler`, makes it a required field, and cuts out the spec (handler is a top-level field).

##### Cluster Autoscaler

* Cluster autoscaler is now GA
* Cluster support size is increased to 1000 nodes
* Respect graceful pod termination of up to 10 minutes
* Handle zone stock-outs and failures
* Improve monitoring and error reporting

#### Container Runtime Interface (CRI)

* Fix panic in ControllerManager on GCE when it has a problem with creating external loadbalancer healthcheck ([#52646](https://github.com/kubernetes/kubernetes/pull/52646), [@gmarek](https://github.com/gmarek))
