- Add --permit-address-sharing flag to `kube-apiserver` to listen with `SO_REUSEADDR`. While allowing to listen on wildcard IPs like 0.0.0.0 and specific IPs in parallel, it avoids waiting for the kernel to release socket in `TIME_WAIT` state, and hence, considerably reducing `kube-apiserver` restart times under certain conditions. ([#93861](https://github.com/kubernetes/kubernetes/pull/93861),...

- In dual-stack bare-metal clusters, you can now pass dual-stack IPs to `kubelet --node-ip`.
  eg: `kubelet --node-ip 10.1.0.5,fd01::0005`. This is not yet supported for non-bare-metal
  clusters.
  
  In dual-stack clusters where nodes have dual-stack addresses, hostNetwork pods

- Apiserver will now reject connection attempts to `0.0.0.0/::` when handling a proxy subresource request. ([#107402](https://github.com/kubernetes/kubernetes/pull/107402), [@anguslees](https://github.com/anguslees))

- Kube-proxy IP family will be determined by the nodeIP used by the proxier. The order of precedence is:
  1. the configured --bind-address if the bind address is not 0.0.0.0 or ::
  2. the primary IP from the Node object, if set.
