### SIG Scheduling

- Added metrics for volume scheduling operations ([#59529](https://github.com/kubernetes/kubernetes/pull/59529), [@wackxu](https://github.com/wackxu))
- Improved memory use and performance when processing large numbers of pods containing tolerations ([#65350](https://github.com/kubernetes/kubernetes/pull/65350), [@liggitt](https://github.com/liggitt))

    * of DaemonSet Pod already exists, it will be replaced.
    * DaemonSet controller will only perform these operations when creating DaemonSet Pods;
    * and those operations will only modify the Pods of DaemonSet, no changes are made to the
    * `.spec.template` of DaemonSet.

* Fix cluster autoscaler addon permissions so it can access batch/job. ([#69858](https://github.com/kubernetes/kubernetes/pull/69858), [@losipiuk](https://github.com/losipiuk))
* Add tolerations for Stackdriver Logging and Metadata Agents. ([#69737](https://github.com/kubernetes/kubernetes/pull/69737), [@qingling128](https://github.com/qingling128))
