- Kube-proxy: Added dual-stack IPv4/IPv6 support to the iptables proxier. ([#82462](https://github.com/kubernetes/kubernetes/pull/82462), [@vllry](https://github.com/vllry)) [SIG Network]
- Kubeadm now supports automatic calculations of dual-stack node cidr masks to kube-controller-manager. ([#85609](https://github.com/kubernetes/kubernetes/pull/85609), [@Arvinderpal](https://github.com/Arvinderpal)) [SIG Cluster Lifecycle]

- Fixed a bug in HorizontalPodAutoscaler. HPAs with `ContainerResource` metrics no longer return an error when container metrics are missing. Instead they use the same logic as `Resource` metrics to perform calculations.

- Optimized `NodeUnschedulable` Filter to avoid unnecessary calculations. ([#119399](https://github.com/kubernetes/kubernetes/pull/119399), [@wackxu](https://github.com/wackxu))

- Set kubelet option `--volume-stats-agg-period` to negative value to disable volume calculations. ([#96675](https://github.com/kubernetes/kubernetes/pull/96675), [@pacoxu](https://github.com/pacoxu)) [SIG Node]
