### **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. ([#53417](https://github.com/kubernetes/kubernetes/pull/53417),[ @crassirostris](https://github.com/crassirostris))

- Fixed clearing of rate-limiter for the queue of checks for cleaning stale pod disruption conditions. The bug could result in the PDB synchronization updates firing too often or the pod disruption cleanups taking too long to happen. ([#114770](https://github.com/kubernet...

- 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))

### Other (Cleanup or Flake)

- Updates konnectivity-network-proxy to v0.0.27. This includes a memory leak fix for the network proxy ([#107188](https://github.com/kubernetes/kubernetes/pull/107188), [@rata](https://github.com/rata)) [SIG API Machinery and Cloud Provider]

### Changed

* Added a parametrizable priority function mapping requested/capacity ratio to priority. This function is disabled by default and can be enabled via the scheduler policy config file.
([#63929](https://github.com/kubernetes/kubernetes/pull/63929), [@losipiuk](https://github.com/losipiuk))

- Updates the `requestedToCapacityRatioArguments` to add resources parameter that allows the users to specify the resource name along with weights for each resource to score nodes based on the request to capacity ratio. ([#77688](https://github.com/kubernetes/kubernetes/pull/77688), [@sudeshsh](https://github.com/sudeshsh))

- client-go discovery clients constructed using `NewDiscoveryClientForConfig` or `NewDiscoveryClientForConfigOrDie` default to rate limits that cause normal discovery request patterns to take several seconds. This is fixed in https://issue.k8s.io/86168 and will be resolved in v1.17.1. As a workaround, the `Burst` value can be adjusted higher in the rest.Config passed into `New...
