There are frequent messages in Rancher 2.7.1 telling me Pod Security Policies are deprecated. I cannot remember having touched any of these, so how comes that Rancher doesn't leave me alone and starts using the new Pod Security Standards and Admissions under the hood?

It's a relevant warning that if you upgrade to K8s >v1.24.x AND use PSP's you will find that things blow up. You'd be surprised how many people go ahead and "do stuff" without reading release notes or understanding what they are actually doing.

Maybe its just me, but IMHO Rancher's documentation about the migration from PSPs to PSAs is confusing. And the Release Notes are not very helpful in this case, either. The big picture is missing.

There’s an open issue about it https://github.com/rancher/rancher/issues/41455
