- kube-proxy: HealthzBindAddress and MetricsBindAddress now support ipv6 addresses. ([#76320](https://github.com/kubernetes/kubernetes/pull/76320), [@JieJhih](https://github.com/JieJhih))

- Fixing issue with Winkernel Proxier - IPV6 load balancer policies are missing when service is configured with ipFamilyPolicy: RequireDualStack ([#115616](https://github.com/kubernetes/kubernetes/pull/115616), [@princepereira](https://github.com/princepereira)) [SIG Network]

- Added support to the kube-proxy nodePortAddresses / --nodeport-addresses option to
  accept the value "primary", meaning to only listen for NodePort connections
  on the node's primary IPv4 and/or IPv6 address (according to the Node object).
  This is strongly recommended, if you were not previously using
  --nodeport-addresses, to avoid surprising behavior.

### OpenStack

* Fixed a bug in the OpenStack cloud provider where dual stack deployments (IPv4 and IPv6) did not work well when using kubenet as the network plugin. ([#59749](https://github.com/kubernetes/kubernetes/pull/59749), [@zioproto](https://github.com/zioproto))

- Fixed mounting of NFS volumes when IPv6 address is used as a server. ([#101067](https://github.com/kubernetes/kubernetes/pull/101067), [@Elbehery](https://github.com/Elbehery)) [SIG Storage]
