Also, compute the backoff delay more accurately for deleted pods. ([#119466](https://github.com/kubernetes/kubernetes/pull/119466), [@mimowo](https://github.com/mimowo)) [SIG Apps]

* Caching added to the OIDC client auth plugin to fix races and reduce the time kubectl commands using this plugin take by several seconds. ([#38167](https://github.com/kubernetes/kubernetes/pull/38167), [@ericchiang](https://github.com/ericchiang))

There is no mitigation from this issue.  Cluster admins should take care to secure aggregated API servers and should not grant access to mutate `APIService`s to untrusted parties.

**Affected Versions**:
  - kube-apiserver v1.25.0
  - kube-apiserver v1.24.0 - v1.24.4

  - Aggregated discovery requests can now timeout. Aggregated API servers must complete discovery calls within 5 seconds (other requests can take longer). Use the feature gate `EnableAggregatedDiscoveryTimeout=false` to temporarily revert behavior to the previous 30 second timeout if required (the temporary `EnableAggregatedDiscoveryTimeout` feature gate will be removed in v1.17).

- Fixed a 1.18 regression in wait.Forever that skips the backoff period on the first repeat ([#90476](https://github.com/kubernetes/kubernetes/pull/90476), [@zhan849](https://github.com/zhan849)) [SIG API Machinery]
- Fixed a bug that mistake use newObj as oldObj in endpoint slice update. ([#92339](https://github.com/kubernetes/kubernetes/pull/92339), [@fatkun](https://github.com/fatkun)) [SIG Apps and Network]

- Fix the regression with the slow pods termination. Before this fix pods may take an additional time to terminate - up to one minute. Reversing the change that ensured that CNI resources cleaned up when the pod is removed on API server. ([#97980](https://github.com/kubernetes/kubernetes/pull/97980), [@SergeyKanzhelev](https://g...

- 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.
