- Adds `--as-uid` flag to `kubectl` to allow uid impersonation in the same way as user and group impersonation. ([#105794](https://github.com/kubernetes/kubernetes/pull/105794), [@margocrawf](https://github.com/margocrawf))

* Validate involvedObject.Namespace matches event.Namespace ([#30533](https://github.com/kubernetes/kubernetes/pull/30533), [@liggitt](https://github.com/liggitt))
* allow group impersonation ([#30803](https://github.com/kubernetes/kubernetes/pull/30803), [@deads2k](https://github.com/deads2k))

  * The oidc client plugin has reduce round trips and fix scopes requested ([#45317](https://github.com/kubernetes/kubernetes/pull/45317), [@ericchiang](https://github.com/ericchiang))

  * API requests using impersonation now include the system:authenticated group in the impersonated user automatically. ([#44076](https://github.com/kubernetes/kubernetes/pull/44076), [@liggitt](https://github.com/liggitt))

* The `--insecure-allow-any-token` flag has been removed from the API server. Users of the flag should use impersonation headers instead for debugging. ([#49045](https://github.com/kubernetes/kubernetes/pull/49045), [@ericchiang](https://github.com/ericchiang))

- 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))
