- Kubernetes is built using golang 1.17. This version of go removes the ability to use a `GODEBUG=x509ignoreCN=0` environment setting to re-enable deprecated legacy behavior of treating the CommonName of X.509 serving certificates as a host name. This behavior has been disabled by default since Kubernetes 1.19 / go 1.15. Serving certificates used by admission webhooks, custom resource conversion webhooks, and aggregated API servers must now include valid Subject Alternative Names. If...

power to both local storage and Persistent Volumes. [Mount namespace propagation](https://github.com/kubernetes/enhancements/issues/432) allows a container to mount a volume as rslave so that host mounts can be seen inside the container, or as rshared so that mounts made inside a container can be seen by the host. (Note that this is [not supported on Windows](https://github.com/kubernetes/kubernetes/pull/60275).)

  * **WARNING:** A [known issue](https://github.com/kubernetes/kubernetes/issues/44041)
    in v1.6.0 causes `Pod.Spec.HostPid` (using the host PID namespace for the pod) to always
    be false. Please wait for v1.6.2, which will include a fix for this issue.
* Various scheduling features have graduated to beta:

- The `baseline` and `restricted` pod security admission levels blocked setting the `host` field on probe and lifecycle handlers. ([#125271](https://github.com/kubernetes/kubernetes/pull/125271), [@tssurya](https://github.com/tssurya)) [SIG Auth, Node and Testing]

- Mounts `/home/kubernetes/bin/nvidia/vulkan/icd.d` on the host to `/etc/vulkan/icd.d` inside containers requesting GPU. ([#78868](https://github.com/kubernetes/kubernetes/pull/78868), [@chardch](https://github.com/chardch))

- Kubeadm: now sets the host `OS` environment variables when executing `crictl` during image pulls. This fixed a bug where `*PROXY` environment variables did not affect `crictl` internet connectivity. ([#110134](https://github.com/kubernetes/kubernetes/pull/110134), [@mk46](h...

* Users may now execute `get-kube-binaries.sh` to request a client for an OS/Arch unlike the one of the host on which the script is invoked. ([#74889](https://github.com/kubernetes/kubernetes/pull/74889), [@akutz](https://github.com/akutz))
