- Fixed bug in beta aggregated discovery endpoint which caused CRD discovery information to be temporarily missing when an Aggregated APIService with the same GroupVersion is deleted (and vice versa). ([#116770](https://github.com/kubernetes/kubernetes/pull/116770), [@alexzielenski](https://github.com/alexzielenski))

tes.io/pod` and `container.seccomp.security.alpha.kubernetes.io/...` annotations are now deprecated, and will be removed in Kubernetes v1.22.0. Right now, an automatic version skew handling will convert the new field into the annotations and vice versa. This means there is no action required for converting existing workloads in a cluster.

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