  * Pods now have a security context which allows users to specify:

* Demoted controlplane passthrough flags apiserver-extra-args, controller-manager-extra-args, scheduler-extra-args to alpha flags ([#59882](https://github.com/kubernetes/kubernetes/pull/59882), [@kris-nova](https://github.com/kris-nova))
