### Feature

- A new Priority and Fairness metric 'apiserver_flowcontrol_work_estimate_seats_samples' has been added that tracks the estimated seats associated with a request. ([#106628](https://github.com/kubernetes/kubernetes/pull/106628), [@tkashem](https://github.com/tkashem))

- Introduced new apiserver metric `apiserver_flowcontrol_current_inqueue_seats`. This metric is analogous to `apiserver_flowcontrol_current_inqueue_requests`, but tracks the total number of seats, as each request can take more than one seat. ([#119385](https://github.com/kubernetes/kubernetes/pull/119385), [@andrewsykim](https://github.com/andrewsykim))

      iptables, saving a bit of memory/time/cpu. (#106373, @aojea) [SIG Network]
- Watch requests that are delegated to aggregated apiservers no longer reserve concurrency units (seats) in the API Priority and Fairness dispatcher for their entire duration. (#105827, @benluddy) [SIG API Machinery]
