- the IP allocator in v1.17.0 can return errors such as `the cluster IP <ip> for service <service-name> is not within the service CIDR <cidr>; please recreate` in the logs of the kube-apiserver. The cause is incorrect CIDR calculations if the service CIDR (`--service-cluster-ip-range`) is set to bits lower than `/16`. This is fixed in http://issue.k8s.io/86534 and will be resolved in v1.17.1.

- Enforced kubelet to request serving certificates only once it has at least one IP address in the `.status.addresses` of its associated Node object. This avoids requesting DNS-only serving certificates before externally set addresses are in place. Until 1.33, the previous behavior can be opted back into by setting the deprecated `AllowDNSOnlyNodeCSR` feature gate to true in the kubelet. ([#125813](https://github.com/ku...

    * Master: convert service CIDR to list  `--service-cluster-ip-range=<CIDR>,<CIDR>` and make sure `IPv6DualStack` feature flag is turned on. The flag is validated and used as the following:
    * 1. `--service-cluster-ip-range[0]` is consider primary service range, and will be used for any service with `Service.Spec.IPFamily = nil` or any service in the at the time of turning on the feature flag.

- The `apiserver` exposes 4 new metrics that allow to track the status of the Service CIDRs allocations:
      - current number of available IPs per Service CIDR
      - current number of used IPs per Service CIDR
      - total number of allocation per Service CIDR

### SIG-service-catalog
- The Originating Identity feature, which lets the broker know which user that performed an action, is now GA.
- [Namespaced Brokers](https://svc-cat.io/docs/namespaced-broker-resources/), which enable operators to install a broker into a namespace instead of the cluster level, reached GA.

- Fixes service account token admission error in clusters that do not run the service account token controller ([#87029](https://github.com/kubernetes/kubernetes/pull/87029), [@liggitt](https://github.com/liggitt)) [SIG Auth]

  - `--service-account-issuer`, should be set to a URL identifying the API server that will be stable over the cluster lifetime.
  - `--service-account-key-file`, set to one or more files containing one or more public keys used to verify tokens.

**Action required** for Kubernetes cluster administrators and for distributions that manage the cluster Service CIDR.
Kubernetes now allows users to define the cluster Service CIDR via an API object: ServiceCIDR.

* Make kube-proxy service abstraction optional. ([#71355](https://github.com/kubernetes/kubernetes/pull/71355), [@bradhoekstra](https://github.com/bradhoekstra))
    * Add the 'service.kubernetes.io/service-proxy-name' label to a Service to disable the kube-proxy service proxy implementation.
