- Graduating `controller_admission_duration_seconds`, `step_admission_duration_seconds`, `webhook_admission_duration_seconds`, `apiserver_current_inflight_requests` and `apiserver_response_sizes` metrics to stable. ([#106122](https://github.com/kubernetes/kubernetes/pull/106122), [@rezakrimi](https://github.com/rezakrimi)) [SIG API Machinery, Instrumentation and Testing]

- Fixed bug that prevented the alpha feature `PodTopologyLabelAdmission` from working due to checking for the incorrect label key when copying topology labels. This bug delayed the graduation of the feature to beta by an additional release to allow time for meaningful feedback.
