### Action Required

* Moved init-container feature from alpha to beta. ([#31026](https://github.com/kubernetes/kubernetes/pull/31026), [@erictune](https://github.com/erictune))
    * Security Action Required:

  * You *MUST* set `--anonymous-auth=false` flag on your kube-apiserver unless you are a developer testing this feature and understand it.
  If you do not, you risk allowing unauthorized users to access your apiserver.
  * You *MUST* set `--anonymous-auth=false` flag on your federation apiserver unless you are a developer testing this feature and understand it.
    If you do not, you risk allowing unauthorized users to access your federation apiserver.
