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.

* We change the default attach_detach_controller sync period to 1 minute to reduce the query frequency through cloud provider to check whether volumes are attached or not.  ([#41363](https://github.com/kubernetes/kubernetes/pull/41363), [@jingxu97](https://github.com/jingxu97))

A survey conducted in early 2019 by the working group (WG) Long Term Support (LTS) showed that a significant subset of Kubernetes end-users fail to upgrade within the previous 9-month support period. 
A yearly support period provides the cushion end-users appear to desire, and is more in harmony with familiar annual planning cycles.
