- Update the system-validators library to v1.8.0 ([#114060](https://github.com/kubernetes/kubernetes/pull/114060), [@pacoxu](https://github.com/pacoxu)) [SIG Cluster Lifecycle]
- [aws] Fixed a bug which reduces the number of unnecessary calls to STS in the event of assume role failures in the legacy cloud provider ([#110706](https://github.com/kubernetes/kubernetes/pull/110706), [@prateekgogia](https://github.com/prateekgogia)) [SIG Cloud Provider]

- Fix handling of aws-load-balancer-security-groups annotation. Security-Groups assigned with this annotation are no longer modified by kubernetes which is the expected behaviour of most users. Also no unnecessary Security-Groups are created anymore if this annotation is used.

- Avoid GCE API calls when initializing GCE CloudProvider for Kubelets.
  Avoid unnecessary GCE API calls when adding IP alises or reflecting them in Node object in GCE cloud provider. ([#96864](https://github.com/kubernetes/kubernetes/pull/96864), [@tosi3k](https://github.com/tosi3k)) [SIG Apps, Cloud Provider and Network]

* UDP connections now support graceful termination in IPVS mode ([#71515](https://github.com/kubernetes/kubernetes/pull/71515), [@lbernail](https://github.com/lbernail))
* Fix a potential bug that scheduler preempts unnecessary pods. ([#70898](https://github.com/kubernetes/kubernetes/pull/70898), [@Huang-Wei](https://github.com/Huang-Wei))

* Kubernetes version command line parameter in kubeadm has been updated to drop an unnecessary redirection from ci/latest.txt to ci-cross/latest.txt. Users should know exactly where the builds are stored on Google Cloud storage buckets from now on. For example for 1.9 and 1.10, users can specify ci/latest-1.9 and ci/latest-1.10 as the CI...
