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:

- The NodeAffinity plugin implements the PreFilter extension, offering enhanced performance for Filter. ([#99213](https://github.com/kubernetes/kubernetes/pull/99213), [@AliceZhang2016](https://github.com/AliceZhang2016)) [SIG Scheduling]

### (No, really, you MUST read this before you upgrade)

    to learn more.
*   Adds optional `exclude_cols` parameter to CsvDataset. This parameter is the
    complement of `select_cols`; at most one of these should be specified.
*   We have implemented an optimization which reorders data-discarding
    transformations such as `take` and `shard` to happen earlier in the dataset

### Deprecation

* Extends the VolumeSubpathEnvExpansion alpha feature to support environment variable expansion ([#71351](https://github.com/kubernetes/kubernetes/pull/71351), [@kevtaylor](https://github.com/kevtaylor))
    * Implements subPathExpr field for expanding environment variables into a subPath
    * The fields subPathExpr and subPath are mutually exclusive
    * Note: This is a breaking change from the previous version of this alpha feature

*   [alpha] [rktlet](https://github.com/kubernetes-incubator/rktlet): CRI implementation for the rkt runtime is now v0.1.0. [[@iaguis](https://github.com/iaguis)]
    *   This is the first release of rktlet and it implements support for the CRI including fetching images, running pods, CNI networking, logging and exec.
This release passes 129/145 Kubernetes e2e conformance tests.

* kube-apiserver: oidc authentication now supports requiring specific claims with `--oidc-required-claim=<claim>=<value>` ([#62136](https://github.com/kubernetes/kubernetes/pull/62136), [@rithujohn191](https://github.com/rithujohn191))
* Implements verbosity logging feature for kubeadm commands ([#57661](https://github.com/kubernetes/kubernetes/pull/57661), [@vbmade2000](https://github.com/vbmade2000))

* In anticipation of CSI 1.0 in the next release, Kubernetes 1.12 calls the CSI `NodeGetInfo` RPC instead of `NodeGetId` RPC. Ensure your CSI Driver implements `NodeGetInfo(...)` before upgrading to 1.12. [@saad-ali](https://github.com/kubernetes/kubernetes/issues/68688)

- Revert Go version used to build Kubernetes to 1.23.0 ([#127861](https://github.com/kubernetes/kubernetes/pull/127861), [@xmudrii](https://github.com/xmudrii)) [SIG Release and Testing]
- The scheduler implements QueueingHint in VolumeBinding plugin's CSIDriver event, which enhances the throughput of scheduling. ([#125171](https://github.com/kubernetes/kubernetes/pull/125171), [@YamasouA](https://github.com/YamasouA)) [SIG Scheduling and Storage]
