* New flag --endpoint-updates-batch-period in kube-controller-manager can be used to reduce number of endpoints updates generated by pod changes. ([#80509](https://github.com/kubernetes/kubernetes/pull/80509), [@mborsz](https://github.com/mborsz))

* 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))

- Reduced GCE log rotation check from 1 hour to every 5 minutes.  Rotation policy is unchanged (new day starts, log file size > 100MB). ([#72062](https://github.com/kubernetes/kubernetes/pull/72062), [@jpbetz](https://github.com/jpbetz))

### Network

- Reduce vSphere volume name to 63 characters ([#100404](https://github.com/kubernetes/kubernetes/pull/100404), [@gnufied](https://github.com/gnufied)) [SIG Storage]

- Reduce event spam during volume operation errors in Portworx in-tree driver ([#135192](https://github.com/kubernetes/kubernetes/pull/135192), [@gohilankit](https://github.com/gohilankit)) [SIG Storage]

### Other (Cleanup or Flake)

- Add flag --lease-reuse-duration-seconds for kube-apiserver to config etcd lease reuse duration. ([#97009](https://github.com/kubernetes/kubernetes/pull/97009), [@lingsamuel](https://github.com/lingsamuel)) [SIG API Machinery and Scalability]

- Scheduler volumebinding: leveraged `PreFilterResult` to reduce down to only
  eligible node(s) for pod with bound claim(s) to local `PersistentVolume(s)` ([#109877](https://github.com/kubernetes/kubernetes/pull/109877), [@yibozhuang](https://github.com/yibozhuang))
