- Extended the NodePorts scheduling plugin to consider hostPorts used by restartable init containers. ([#132040](https://github.com/kubernetes/kubernetes/pull/132040), [@avrittrohwer](https://github.com/avrittrohwer)) [SIG Scheduling and Testing]

- kubeadm: consider --bind-address or --advertise-address and --secure-port for control plane components when the feature gate WaitForAllControlPlaneComponents is enabled. Use /livez for kube-apiserver and kube-scheduler, but continue using /healthz for kube-controller-manager...

the PVC is bound to a PV object. During the binding process, if a PVC has a `volumeAttributesClassName` field set, the controller will only consider volumes that have the same `volumeAttributesClassName` as the PVC. If the `volumeAttributesClassName` field is not set or set to an empty string, only volumes with empty `volumeAttributesClassName` will be considered.

In addition, support for NVMe disks has been added to Kubernetes, and a service of type LoadBalancer can now be backed with an NLB instead of an ELB (alpha).

### Azure

- The `volume_zone` plugin will consider `beta` labels as `GA` labels during the scheduling
  process. Therefore, if the values of the labels are the same, PVs with `beta` labels

### Feature
