- E2e framework: added `--report-complete-ginkgo` and `--report-complete-junit` parameters. They work like `ginkgo --json-report <report dir>/ginkgo/report.json --junit-report <report dir>/ginkgo/report.xml`. ([#115678](https://github.com/kubernetes/kubernetes/pull/115678), [@pohly](https://github.com/pohly)) [SIG Testing]

- Added a kubelet metric `container_aligned_compute_resources_count`  to report the count of containers getting aligned compute resources. ([#127155](https://github.com/kubernetes/kubernetes/pull/127155), [@ffromani](https://github.com/ffromani)) [SIG Node and Testing]

SIG Windows focused on improving reliability for Windows and Kubernetes support

## New Features

- kubelet: When node lease feature is enabled, kubelet reports node status to api server only if there is some change or it didn't report over last report interval. ([#69753](https://github.com/kubernetes/kubernetes/pull/69753), [@wangzhen127](https://github.com/wangzhen127))

- Improved reboot event reporting. The kubelet will only emit one reboot Event when a server-level reboot 

- Fix the bug that the metrics for the cluster IP allocator are incorrectly reported. ([#110027](https://github.com/kubernetes/kubernetes/pull/110027), [@tksm](https://github.com/tksm)) [SIG Instrumentation]

* Fixed EndpointSlice port name validation to match Endpoint port name validation (allowing port names longer than 15 characters) ([#84481](https://github.com/kubernetes/kubernetes/pull/84481), [@robscott](https://github.com/robscott))

* The formerly publicly-available cAdvisor web UI that the kubelet ran on port 4194 by default is now turned off by default. The flag configuring what port to run this UI on `--cadvisor-port` was deprecated in v1.10. Now the default is `--cadvisor-port=0`, in other words, to not run the web server. If you still need to run cAdvisor, the recommended way to run it is via a DaemonSet. Note that the `--cadvisor-port` will be removed in v1.12 ([#63881](https://github.com/kubernetes/kubernetes/pull/63881),...
