The CustomCFSQuotaPeriod alpha feature enables node administrators to change the default period used to enforce CFS quota on a node.  This can improve performance for some workloads that experience latency while using CFS quota with the default measurement period.  Finally, the SIG continues to focus on improving reliability by fixing bugs while working out design and implementation of future features.

## Changelog since v1.8.7

### Other notable changes

* Configurable etcd quota backend bytes in GCE ([#59259](https://github.com/kubernetes/kubernetes/pull/59259), [@wojtek-t](https://github.com/wojtek-t))

- Fixed a potential deadlock in the resource quota controller. Enabled recording partial usage info for quota objects specifying multiple resources, when only some of the resources' usage can be determined. ([#74747](https://github.com/kubernetes/kubernetes/pull/74747), [@liggitt](https://github.com/liggitt))

* kube-controller-manager can now start the quota controller when discovery results can only be partially determined. ([#67433](https://github.com/kubernetes/kubernetes/pull/67433), [@deads2k](https://github.com/deads2k))

* Moved qos to api.helpers. ([#44906](https://github.com/kubernetes/kubernetes/pull/44906), [@k82cn](https://github.com/k82cn))

### API Change

- 1. PodAffinityTerm includes a namespaceSelector field to allow selecting eligible namespaces based on their labels. 

* Azure cloudprovider: Reduce the polling delay for all azure clients to 5 seconds. This should speed up some operations at the cost of some additional quota. ([#43699](https://github.com/kubernetes/kubernetes/pull/43699), [@colemickens](https://github.com/colemickens))

- The `podAffinity`, `NamespaceSelector` and the associated `CrossNamespaceAffinity` quota scope features graduate to Beta and they are now enabled by default. ([#101496](https://github.com/kubernetes/kubernetes/pull/101496), [@ahg-g](https://github.com/ahg-g))
