- Kube-scheduler implements scheduling hints for the CSILimit plugin.
  The scheduling hints allow the scheduler to retry scheduling a Pod that was previously rejected by the CSILimit plugin if a deleted pod has a PVC from the same driver. ([#121508](https://github.com/kubernetes/kubernetes/pull/121508), [@utam0k](https://github.com/utam0k)) [SIG Scheduling and Storage]
- Kube-scheduler implements scheduling hints for the InterPodAffinity plugin.

A map is an unordered group of elements of one type, called the
element type, indexed by a set of unique <i>keys</i> of another type,
called the key type.

* Fixed charm issue where docker login would run prior to daemon options being set.  ([#59396](https://github.com/kubernetes/kubernetes/pull/59396), [@kwmonroe](https://github.com/kwmonroe))

- Added support for cloud provider integrations to supply optional, per-Node custom labels that will be
  applied to Nodes by the node controller.
  Extra labels will only be applied where the cloud provider integration implements this. ([#123223](https://github.com/kubernetes/kubernetes/pull/123223), [@mmerkes](https://github.com/mmerkes)) [SIG Cloud Provider]

- `kube-scheduler` implements scheduling hints for the `NodeAffinity` plugin.
  The scheduling hints allow the scheduler to only retry scheduling a `Pod`

- vSphereVolume implements Raw Block Volume Support  ([#68761](https://github.com/kubernetes/kubernetes/pull/68761), [@fanzhangio](https://github.com/fanzhangio))

- `wait.ContextForChannel()` now implements the context.Context interface and
  does not return a cancellation function. ([#115140](https://github.com/kubernetes/kubernetes/pull/115140), [@smarterclayton](https://github.com/smarterclayton))

## Dependencies

* Implements rolling update for StatefulSets. Updates can be performed using the RollingUpdate, Paritioned, or OnDelete strategies. OnDelete implements the manual behavior from 1.6. status now tracks  ([#46669](https://github.com/kubernetes/kubernetes/pull/46669), [@kow3ns](https://github.com/kow3ns))

Volume cloning enables users to specify another PVC as a "DataSource" when provisioning a new volume. If the underlying storage system supports this functionality and implements the "CLONE_VOLUME" capability in its CSI driver, then the new volume becomes a clone of the source volume.

These changes are reflected in the following Kubernetes enhancements:
