### Deprecation of klog specific flags

To simplify the code base, several [logging flags got marked as deprecated](https://kubernetes.io/docs/concepts/cluster-administration/system-logs/#klog) in Kubernetes 1.23.
The code which implements them will be removed in a future release, so users of those need to start replacing the deprecated flags with some alternative solutions.

### Software Supply Chain SLSA Level 1 Compliance in the Kubernetes Release Process

* 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

* 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))

*   [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.

* 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)
