- Bumped cadvisor version to `v0.47.3`. ([#119225](https://github.com/kubernetes/kubernetes/pull/119225), [@iholder101](https://github.com/iholder101))
- CI job `ci-kubernetes-node-arm64-ubuntu-serial` will test node e2e on arm64, `use-dockerized-build` and `target-build-arch` are required to run this job. ([#118567](https://github.com/kubernetes/kubernetes/pull/118567), [@chendave](https://github.com/chendave))

- kubeadm: improved the overall logic, error handling, and output messages when waiting for the kubelet and API server `/healthz` endpoints to return `OK`. The kubelet and API server checks no longer ran in parallel, but one after another (in serial).
