The shift operators implement arithmetic shifts if the left operand is a signed
integer and logical shifts if it is an unsigned integer.
There is no upper limit on the shift count. Shifts behave
as if the left operand is shifted <code>n</code> times by 1 for a shift
count of <code>n</code>.

- Kube-scheduler implements scheduling hints for the VolumeRestriction plugin.
  Scheduling hints allow the scheduler to retry scheduling Pods that were previously rejected by the VolumeRestriction plugin if a new pvc added, and the pvc belongs to pod. ([#125280](https://github.com/kubernetes/kubernetes/pull/125280), [@HirazawaUi](https://github.com/HirazawaUi)) [SIG Scheduling and Storage]
- Kube-scheduler implements scheduling hints for the VolumeZone plugin.

- Kube-scheduler implemented scheduling hints for the `NodeAffinity` plugin. The scheduling hints allowed the scheduler to only retry scheduling a Pod that had been previously rejected by the `NodeAffinity` plugin if a new Node or a Node update matched the Pod's node affinity.

- Topology Aware Hints now ignores unready endpoints when assigning hints. ([#106510](https://github.com/kubernetes/kubernetes/pull/106510), [@robscott](https://github.com/robscott))

* Fixed documentation typo in IPVS README. ([#56578](https://github.com/kubernetes/kubernetes/pull/56578), [@shift](https://github.com/shift))

* The ConfigOK node condition has been renamed to KubeletConfigOk. ([#59905](https://github.com/kubernetes/kubernetes/pull/59905), [@mtaufen](https://github.com/mtaufen))

- Added validation to ensure that if `service.kubernetes.io/topology-aware-hints` and `service.kubernetes.io/topology-mode` annotations are both set, they are set to the same value.Also Added deprecation warning if `service.kubernetes.io/topology-aware-hints` annotation is used. ([#116612](https://github.com/kubernetes/kubernetes/pull/116612), [@robscott](https://github.com/robscott))

  the `nf_conntrack_tcp_be_liberal` is not set. ([#120412](https://github.com/kubernetes/kubernetes/pull/120412), [@aojea](https://github.com/aojea))
- `kube-scheduler` implemented scheduling hints for the `NodeUnschedulable` plugin.
  The scheduling hints allow the scheduler to only retry scheduling a `Pod`

- Kube-proxy log now shows the "Skipping topology aware endpoint filtering since no hints were provided for zone" warning under the right conditions ([#101857](https://github.com/kubernetes/kubernetes/pull/101857), [@dervoeti](https://github.com/dervoeti)) [SIG Network]

- If scheduling fails on PreBind or Bind, scheduler will retry the failed pod immediately after backoff time, regardless of the reason for failing. In this case EventsToRegister (QHints) will not be taken into consideration before retry. ([#130189](https://github.com/kubernetes/kubernetes/pull/130189), [@ania-borowiec](https://github.com/ania-borowiec)) [SIG Scheduling]

- Remove support for the Service `topologyKeys` field (alpha) and the `kube-proxy` implementation of it. This field was deprecated several cycles ago. This functionality is replaced by the combination of automatic topology hints per-endpoint (alpha) and the Service `internalTrafficPolicy` field (alpha).
