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.

- 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`

* 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))

- The `TopologyAwareHints` feature gate is now enabled by default. This will allow users to opt-in to Topology Aware Hints by setting the `service.kubernetes.io/topology-aware-hints` on a Service. This will not affect any Services without that annotation set. ([#108747](https://github.com/kubernetes/kubernetes/pull/108747), [@robscott](https://github.com/robscott))

- Output a log as v4-level when a probe is triggered and shift the periodic timer of ReadinessProbe after manual run. ([#119089](https://github.com/kubernetes/kubernetes/pull/119089), [@mochizuki875](https://github.com/mochizuki875))

- Fixes spammy incorrect "Ignoring same-zone topology hints for service since no hints were provided for zone" messages in the kube-proxy logs. ([#133527](https://github.com/kubernetes/kubernetes/pull/133527), [@danwinship](https://github.com/danwinship)) [SIG Network]
