The Kubernetes community [has written a blog post about this in detail](https://blog.k8s.io/2020/12/02/dont-panic-kubernetes-and-docker/) with [a dedicated FAQ page for it](https://blog.k8s.io/2020/12/02/dockershim-faq/).

To learn more about the feature, please refer to the official [seccomp tutorial](https://kubernetes.io/docs/tutorials/clusters/seccomp/#enable-the-use-of-runtimedefault-as-the-default-seccomp-profile-for-all-workloads).

### Other (Cleanup or Flake)

- Fixes the flooding warning messages about setting volume ownership for configmap/secret volumes ([#92878](https://github.com/kubernetes/kubernetes/pull/92878), [@jvanz](https://github.com/jvanz)) [SIG Instrumentation, Node and Storage]

- Removed `GA` feature gate about `CSIMigrationvSphere`. ([#121291](https://github.com/kubernetes/kubernetes/pull/121291), [@bzsuni](https://github.com/bzsuni))
- Removed `GA` feature gate about `ProbeTerminationGracePeriod`. ([#121257](https://github.com/kubernetes/kubernetes/pull/121257), [@bzsuni](https://github.com/bzsuni))

* `kubefed init` correctly checks for RBAC API enablement. ([#48077](https://github.com/kubernetes/kubernetes/pull/48077), [@liggitt](https://github.com/liggitt))
* `kubectl api-versions` now always fetches information about enabled API groups and versions instead of using the local cache. ([#48016](https://github.com/kubernetes/kubernetes/pull/48016), [@liggitt](https://github.com/liggitt))

- Upon receiving a LIST request with an expired continue token, the apiserver now returns a continue token together with the 410 "the from parameter is too old" error. If the client does not care about getting a list from a consistent snapshot, the client can use this token to continue listing from the next key, but the returned chunk will be from the latest snapshot.

- `kubectl auth reconcile` now outputs details about what changes are being made ([#71564](https://github.com/kubernetes/kubernetes/pull/71564), [@liggitt](https://github.com/liggitt))

- Validation rules for Custom Resource Definitions can be written in the [CEL expression language](https://github.com/google/cel-spec)...

- Revised the comment about the feature-gate level for PodFailurePolicy from alpha to beta ([#117814](https://github.com/kubernetes/kubernetes/pull/117814), [@kerthcet](https://github.com/kerthcet)) [SIG Apps]

### Feature

- Kubelet podresources API now provides the information about active pods only. ([#79409](https://github.com/kubernetes/kubernetes/pull/79409), [@takmatsu](https://github.com/takmatsu)) [SIG Node]
