- `audit.k8s.io/v1beta1` and `audit.k8s.io/v1alpha1` audit policy configuration and audit events are deprecated in favor of `audit.k8s.io/v1`, available since v1.13. kube-apiserver invocations that specify alpha or beta policy configurations with `--audit-policy-file`, or explicitly request alpha or beta audit events with `--audit-log-version` / `--audit-webhook-version` must update to use `audit.k8s.io/v1` and accept `audit.k8s.io/v1` events prior...

### API Change

- A new field `omitManagedFields` has been added to both `audit.Policy` and `audit.PolicyRule` 
  so cluster operators can opt in to omit managed fields of the request and response bodies from 

* Introduce truncating audit backend that can be enabled by passing --audit-log-truncate-enabled or --audit-webhook-truncate-enabled flag to the apiserver to limit the size of individual audit events and batches of events. ([#64024](https://github.com/kubernetes/kubernetes/pull/64024), [@loburm](https://github.com/loburm))

* audit.k8s.io api group is upgraded from v1beta1 to v1. ([#65891](https://github.com/kubernetes/kubernetes/pull/65891), [@CaoShuFeng](https://github.com/CaoShuFeng))
    * Deprecated element metav1.ObjectMeta and Timestamp are removed from audit Events in v1 version.
    * Default value of option --audit-webhook-version and --audit-log-version will be changed from `audit.k8s.io/v1beta1` to `audit.k8s.io/v1` in release 1.13

- **API Machinery**
  - [alpha] Generate audit logs for every request user performs against secured API server endpoint. ([docs](http://kubernetes.io/docs/admin/audit/)) ([kubernetes/features#22](https://github.com/kubernetes/enhancements/issues/22))

* Added generators for `apps/v1` deployments. ([#61288](https://github.com/kubernetes/kubernetes/pull/61288), [@ayushpateria](https://github.com/ayushpateria))

### SIG Auth

* RBAC information is now included in audit logs via audit.Event annotations:
    * authorization.k8s.io/decision = {allow, forbid}

* The kube-apiserver [basic audit log](https://kubernetes.io/docs/admin/audit/) can be enabled in GCE by exporting the environment variable `ENABLE_APISERVER_BASIC_AUDIT=true` before running `cluster/kube-up.sh`. This will log to `/var/log/kube-apiserver-audit.log` and use the same `logrotate` settings as `/var/log/kube-apiserver.log`. ([#41211](https://github.com/kubernetes/kubernetes/pull/41211),...
