 PodSecurityPolicy was initially [deprecated in v1.21](/blog/2021/04/06/podsecuritypolicy-deprecation-past-present-and-future/), and with the release of v1.25, it has been removed.

This is particularly useful for troubleshooting when you need to examine another container but cannot use `kubectl exec` because that container has crashed or its image lacks debugging utilities. Ephemeral containers graduated to Beta in Kubernetes v1.23, and with this release, the feature graduates to Stable.
