- Node `ipam` controller now exposes metrics `cidrset_cidrs_max_total` and `multicidrset_cidrs_max_total` with information about the max number of CIDRs that can be allocated. ([#112260](https://github.com/kubernetes/kubernetes/pull/112260), [@aryan9600](https://github.com/aryan9600))

    * --application_metrics_count_limit
    * --boot_id_file
    * --container_hints

- KEP-1880: Users of the new feature to add multiple service CIDR will use by default a dual-write strategy on the new ClusterIP allocators to avoid the problem of possible duplicate IPs allocated to Services when running skewed kube-apiservers using different allocators. They can opt-out of this behavior by enabled...

- Use NLB Subnet CIDRs instead of VPC CIDRs in Health Check SG Rules ([#93515](https://github.com/kubernetes/kubernetes/pull/93515), [@t0rr3sp3dr0](https://github.com/t0rr3sp3dr0)) [SIG Cloud Provider]

### Other (Cleanup or Flake)

* You can now use `--ipvs-exclude-cidrs` to specify a list of CIDR's which the IPVS proxier should not touch when cleaning up IPVS rules. ([#62083](https://github.com/kubernetes/kubernetes/pull/62083), [@rramkumar1](https://github.com/rramkumar1))

  and removed `--short` flag entirely. ([#116720](https://github.com/kubernetes/kubernetes/pull/116720), [@soltysh](https://github.com/soltysh))
- Kube-controller-manager deprecate `--volume-host-cidr-denylist` and `--volume-host-allow-local-loopback` flags. ([#118128](https://github.com/kubernetes/kubernetes/pull/118128), [@carlory](https://github.com/carlory)) [SIG API Machinery, Apps, Network, Node, Storage and Testing]

  have been validated.
* The following deprecated kubelet flags are removed: `--config`, `--auth-path`,
  `--resource-container`, `--system-container`, `--reconcile-cidr`
* Remove the temporary fix for pre-1.0 mirror pods. Upgrade directly from
  pre-1.0 to 1.6 kubelet is not supported.
* Fluentd was migrated to Daemon Set, which targets nodes with

### Cloud Provider

- The GCE-only flag `cloud-provider-gce-lb-src-cidrs` is now optional for external cloud providers. ([#76627](https://github.com/kubernetes/kubernetes/pull/76627), [@timoreimann](https://github.com/timoreimann))

### Bug or Regression

- Fix a bug that caused to panic the apiserver when trying to allocate a Service with a dynamic ClusterIP and it has been configured with Service CIDRs with a /28 mask for IPv4 and a /124 mask for IPv6 ([#115334](https://github.com/kubernetes/kubernetes/pull/115334), [@aojea](https://github.com/aojea)) [SIG Network and Testing]

- Sped up kubelet start time by executing an immediate runtime and node status update when the Kubelet sees that it has a CIDR. ([#67031](https://github.com/kubernetes/kubernetes/pull/67031), [@krzysztof-jastrzebski](https://github.com/krzysztof-jastrzebski))
