- Apiserver `/healthz/etcd` endpoint rate limits the number of forwarded health check requests to the etcd backends, answering with the last known state if the rate limit is exceeded. The rate limit is based on 1/2 of the timeout configured, with no burst allowed. ([#112046](https://github.com/kubernetes/kubernetes/pull/112046), [@aojea](https://github.com/aojea))...

                                response modification, implementing authentication

                                guarantee/conformance is defined based on the type
                                of the filter.

* Separate current ARM rate limiter into read/write ([#59830](https://github.com/kubernetes/kubernetes/pull/59830), [@khenidak](https://github.com/khenidak))

- kube-apiserver: fixes error creating system priority classes when starting multiple apiservers simultaneously ([#67372](https://github.com/kubernetes/kubernetes/pull/67372), [@tanshanshan](https://github.com/tanshanshan))
-  Forget rate limit when CRD establish controller successfully updated CRD condition ([#67370](https://github.com/kubernetes/kubernetes/pull/67370), [@yue9944882](https://github.com/yue9944882))

- Fixed a bug that caused a DaemonSet rolling update to hang when its pod gets stuck at terminating.  ([#77773](https://github.com/kubernetes/kubernetes/pull/77773), [@DaiHao](https://github.com/DaiHao))
- Route controller now respects rate limiting to the cloud provider on deletion; previously it was only for create. ([#78581](https://github.com/kubernetes/kubernetes/pull/78581), [@andrewsykim](https://github.com/andrewsykim))

### **Instrumentation**

#### **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.
