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.

*   Termination grace period for the calico/node add-on DaemonSet has been eliminated, reducing downtime during a rolling upgrade or deletion. ([#55015](https://github.com/kubernetes/kubernetes/pull/55015),[ @fasaxc](https://github.com/fasaxc))

* Controller-manager --service-sync-period flag has been removed. (It was never used in the code and should have no user impact.) ([#59359](https://github.com/kubernetes/kubernetes/pull/59359), [@khenidak](https://github.com/khenidak))

* Pods that are marked for deletion and have exceeded their grace period, but are not yet deleted, no longer count toward the resource quota.([#46542](https://github.com/kubernetes/kubernetes/pull/46542))


#### Dynamic Admission Control

- Reduce default NodeStatusReportFrequency to 5 minutes. With this change, periodic node status updates will be send every 5m if node status doesn't change (otherwise they are still send with 10s).

  - The deprecated `--etcd-quorum-read` flag has been removed. Quorum reads are now always enabled when fetching data from etcd. Remove the `--etcd-quorum-read`...
