- Support for the alpha seccomp annotations `seccomp.security.alpha.kubernetes.io/pod` and `container.seccomp.security.alpha.kubernetes.io` were deprecated since v1.19, now have been completely removed. The seccomp fields are no longer auto-populated when pods with seccomp annotations are created. Pods should use the corresponding pod or container `securityContext.seccompProfile` field instead.

You can find more information about how to restrict container system calls with seccomp in the new [documentation page on Kubernetes.io][seccomp-docs]

### Production images moved to community control

- Support for the alpha seccomp annotations `seccomp.security.alpha.kubernetes.io/pod` and `container.seccomp.security.alpha.kubernetes.io`, deprecated since v1.19, was partially removed. Kubelets no longer support the annotations, use of the annotations in static pods is no longer supported, and the seccomp annotations are no longer auto-populated when pods with seccomp fields are created. Auto-population of the seccomp fields from the annotations is planned to be removed...

### Cluster-wide seccomp defaults

A new alpha feature gate `SeccompDefault` has been added to the kubelet, together with a corresponding command line flag `--seccomp-default` and kubelet configuration. If both are enabled, then the kubelet's behavior changes for pods that don't explicitly set a seccomp profile.

- Dockershim security: pod sandbox now always run with `no-new-privileges` and `runtime/default` seccomp profile
  dockershim seccomp: custom profiles can now have smaller seccomp profiles when set at pod level ([#90948](https://github.com/kubernetes/kubernetes/pull/90948), [@pjbgf](https://github.com/pjbgf)) [SIG Node]
