- [Dual-stack] Fixed `generateAPIPodStatus()` of kubelet handling Secondary IP. hostIPs order may not be consistent. If secondary IP is before primary one, current logic adds primary IP twice into `PodIPs`, which leads to error: "may specify no more than one IP for each IP family". ([#116879](https://github.com/kubernetes/kubernetes/pull/116879),...

    * 2. IPv4: api-server will assign an IP from a `service-cluster-ip-range` that is `ipv4` (either the primary or the secondary, according to how they were configured).
    * 2. IPv6: api-server will assign an IP from a `service-cluster-ip-range` that is `ipv6` (either the primary or the secondary, according to how they were configured).
    * Notes (v1.16):
    * 1. IPVS is the only proxy supported (as of v1.16 ) by Dualstack.

- Kubeadm: fix skipped etcd upgrade on secondary control-plane nodes when the command `kubeadm upgrade node` is used. ([#85024](https://github.com/kubernetes/kubernetes/pull/85024), [@neolit123](https://github.com/neolit123))

### CLI Improvements

- Upgrades `IPv6Dualstack` to `Beta` and turns it on by default. New clusters or existing clusters are not be affected until an actor starts adding secondary Pods and service CIDRS CLI flags as described here: [IPv4/IPv6 Dual-stack](https://github.com/kubernetes/enhancements/tree/master/keps/sig-network/563-dual-stack) ([#98969](https://github.com/kubernetes/kubernetes/pull/98969), [@khenidak](https:...

- Fixed a bug with dual stack clusters using the beta feature MultiCIDRServiceAllocator which could not create dual stack Services or Services with IPs in the secondary range. Users who wanted to use this feature in version 1.30 with dual stack clusters could work around the issue by setting the feature gate DisableAllocatorDualWrite to true.
