- Added support for specifying `controlplane` or `cluster` egress selectors in JWT authenticators via the `issuer.egressSelectorType` field in the `AuthenticationConfiguration.jwt` array. If unset, the previous behavior of using no egress selector is preserved. This functionality requires the `StructuredAuthenticationConfigurationEgressSelector`...

- Introduced a new metric `kubelet_admission_rejections_total` to track the number of pods rejected during admission. ([#128556](https://github.com/kubernetes/kubernetes/pull/128556), [@AnishShah](https://github.com/AnishShah))
