- Slow requests that use impersonation can now be tracked via the `apiserver.latency.k8s.io/impersonation` audit event annotation when the ConstrainedImpersonation feature is enabled. ([#137523](https://github.com/kubernetes/kubernetes/pull/137523), [@enj](https://github.com/enj)) [SIG API Machinery, Auth and Testing]...

- Implemented constrained impersonation as described in [KEP-5284](https://kep.k8s.io/5284). ([#134803](https://github.com/kubernetes/kubernetes/pull/134803), [@enj](https://github.com/enj)) [SIG API Machinery, Auth and Testing]

- API Server tracing now includes the latency of authorization, priorityandfairness, impersonation, audit, and authentication filters. ([#113217](https://github.com/kubernetes/kubernetes/pull/113217), [@dashpole](https://github.com/dashpole))
