- 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]

### Other (Cleanup or Flake)

- Reduce logspam when calculating the container resources on linux ([#132272](https://github.com/kubernetes/kubernetes/pull/132272), [@Peac36](https://github.com/Peac36)) [SIG Node]

## Dependencies

### Added

- 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

* Add /bin/tee symlink to bazel build for busybox, so that CI builds have /bin/tee ([#55417](https://github.com/kubernetes/kubernetes/pull/55417), [@justinsb](https://github.com/justinsb))
* Reduce log noise produced by prometheus-to-sd, by bumping it to version 0.2.2. ([#54635](https://github.com/kubernetes/kubernetes/pull/54635), [@loburm](https://github.com/loburm))

- Improve speed of vSphere PV provisioning and reduce number of API calls ([#102350](https://github.com/kubernetes/kubernetes/pull/102350), [@gnufied](https://github.com/gnufied)) [SIG Cloud Provider and Storage]

- Provide IPv6 support for internal load balancer. ([#103794](https://github.com/kubernetes/kubernetes/pull/103794), [@nilo19](https://github.com/nilo19))
- Reduce the number of calls to docker for stats via dockershim. For Windows this reduces the latency when calling docker, for Linux this saves cpu cycles. ([#104287](https://github.com/kubernetes/kubernetes/pull/104287), [@jsturtevant](https://github.com/jsturtevant)) [SIG Node and Windows]
