* 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)
