#### **Audit**

*   Adjust batching audit webhook default parameters: increase queue size, batch size, and initial backoff. Add throttling to the batching audit webhook. Default rate limit is 10 QPS. ([#53417](https://github.com/kubernetes/kubernetes/pull/53417),[ @crassirostris](https://github.com/crassirostris))

* Webhook always retries connection reset error. ([#53947](https://github.com/kubernetes/kubernetes/pull/53947), [@crassirostris](https://github.com/crassirostris))

- EndpointSlice should not contain endpoints for terminating pods ([#89056](https://github.com/kubernetes/kubernetes/pull/89056), [@andrewsykim](https://github.com/andrewsykim)) [SIG Apps and Network]
- Evictions due to pods breaching their ephemeral storage limits are now recorded by the `kubelet_evictions` metric and can be alerted on. ([#87906](https://github.com/kubernetes/kubernetes/pull/87906), [@smarterclayton](https://github.com/smarterclayton)) [SIG Node]

* Log audit backend can now be configured to perform batching before writing events to disk. ([#60237](https://github.com/kubernetes/kubernetes/pull/60237), [@crassirostris](https://github.com/crassirostris))

- Kube-proxy: removed log warning about not using config file. ([#118115](https://github.com/kubernetes/kubernetes/pull/118115), [@TommyStarK](https://github.com/TommyStarK)) [SIG Network]
- Made Job controller batching of syncJob invocations enabled unconditionally (it was conditional on JobReadyPods feature before).

* Defaults for file audit logging backend in batch mode changed: ([#67223](https://github.com/kubernetes/kubernetes/pull/67223), [@tallclair](https://github.com/tallclair))
    * Logs are written 1 at a time (no batching)
    * Only a single writer process (lock contention)
