- A new client side metric `rest_client_request_retries_total` has been added that tracks the number of retries sent to the server, partitioned by status code, verb and host ([#108396](https://github.com/kubernetes/kubernetes/pull/108396), [@tkashem](https://github.com/tkashem))

The seccomp (secure computing mode) support for Kubernetes has graduated to General Availability (GA). This feature can be used to increase the workload security by restricting the system calls for a Pod (applies to all containers) or single containers.

Technically this means that a first class `seccompProfile` field has been added to the Pod and Container `securityContext` objects:

```yaml
securityContext:

- **Apps**
  - [stable] When replica sets cannot create pods, they will now report detail via the API about the underlying reason ([kubernetes/features#120](https://github.com/kubernetes/enhancements/issues/120))

- Set ProcMountType feature to disabled by default, to follow the lead of UserNamespacesSupport (which it relies on). ([#126291](https://github.com/kubernetes/kubernetes/pull/126291), [@haircommander](https://github.com/haircommander)) [SIG Node]
