* MAC Address filter has been fixed in vSphere Cloud Provider, it no longer ignores `00:1c:14` and `00:05:69` prefixes ([#73721](https://github.com/kubernetes/kubernetes/pull/73721), [@frapposelli](https://github.com/frapposelli))

  - removed the ability to set `kubernetes.io`- or `k8s.io`-prefixed labels via `--node-labels`, other than the [specifically allowed labels/prefixes](https://github.com/kubernetes/enhancements/blob/master/keps/sig-auth/279-limit-node-access/README.md#proposal).

    * Setting other `kubernetes.io/`- and `k8s.io/`-prefixed labels using the `--node-labels` flag will produce a warning in v1.13, and be disallowed in v1.15. Setting labels that are not prefixed with `kubernetes.io/` or `k8s.io/` is still permitted.

* The OpenID Connect authenticator can now use a custom prefix, or omit the default prefix, for username and groups claims through the --oidc-username-prefix and --oidc-groups-prefix flags. For example, the authenticator can map a user with the username "jane" to "google:jane" by supplying the "google:" username prefix.

* Allow PSP's to specify a whitelist of allowed paths for host volume based on path prefixes ([#43946](https://github.com/kubernetes/kubernetes/pull/43946), [@jhorwit2](https://github.com/jhorwit2))

* `prefix`: to set the path prefix for a router. Up to now, this was only possible when calling `include_router`.
* `tags`: OpenAPI tags to apply to all the *path operations* in this router.

For example:

```Python
from fastapi import APIRouter, Depends


async def some_dependency():
    return

- Fixes issue where AAD token obtained by kubectl is incompatible with on-behalf-of flow and oidc. The audience claim before this fix has "spn:" prefix. After this fix, "spn:" prefix is omitted.
