will be removed in a future release. This functionality has been migrated to a dedicated v1 API - networking.k8s.io/v1. v1beta1 Network Policies can be upgraded to the v1 API with the [cluster/update-storage-objects.sh script](https://github.com/danwinship/kubernetes/blob/master/cluster/update-storage-objects.sh).

## Changes by Kind

### Feature

- Kubelet TCP and HTTP probes are more effective using networking resources: conntrack entries, sockets, ... 

- Updated the feature MultiCIDRServiceAllocator to beta (disabled by default). Users need to enable the feature gate and the networking v1beta1 group to be able to use this new feature, that allows to dynamically reconfigure Service CIDR ranges.

    A previous release built hyperkube using the debian-hyperkube-base@v1.0.0,
    which was updated to address a CVE in the CNI plugins.
    
    A side-effect of using this new image was that the networking packages
    (namely `iptables`) drifted from the versions used in the kube-proxy images.
  
    The following issues were filed on kube-proxy failures when using hyperkube:

  to GA. Services that do not have the field configured will continue to operate
  with their existing behavior. Refer to the documentation

  for more details. ([#130673](https://github.com/kubernetes/kubernetes/pull/130673), [@gauravkghildiyal](https://github.com/gauravkghildiyal)) [SIG Apps, Network and Testing]

- `Ingress` and `IngressClass` resources have graduated to `networking.k8s.io/v1`. Ingress and IngressClass types in the `extensions/v1beta1` and `networking.k8s.io/v1beta1` API versions are deprecated and will no longer be served in 1.22+. Persisted objects can be accessed via the `networking.k8s.io/v1` API. Notable changes in v1 Ingress objects (v1beta1 field names are unchanged):

delivered incremental improvements to node reliability.

### SIG Network

[SIG Network][] is responsible for networking components, APIs, and plugins in Kubernetes.

For the 1.8 release, SIG Network enhanced the NetworkPolicy API to support pod egress traffic policies.

- kubeadm now works better when not connected to the Internet. In addition,  common kubeadm commands will now work without an available networking interface. ([#67397](https://github.com/kubernetes/kubernetes/pull/67397), [@neolit123](https://github.com/neolit123))
