- `-- kube-controller-manager`
  `--node-cidr-mask-size-ipv4 int32`     Default: 24. Mask size for IPv4 node-cidr in dual-stack cluster.
`--node-cidr-mask-size-ipv6 int32`     Default: 64. Mask size for IPv6 node-cidr in dual-stack cluster.

    These 2 flags can be used only for dual-stack clusters. For non dual-stack clusters, continue to use  `--node-cidr-mask-size` flag to configure the mask size.

<p>
A (variable of) type <code>T</code> has <i>variable size</i> if <code>T</code>
is a <a href="#Type_parameter_declarations">type parameter</a>, or if it is an
array or struct type containing elements
or fields of variable size. Otherwise the size is <i>constant</i>.
Calls to <code>Alignof</code>, <code>Offsetof</code>, and <code>Sizeof</code>

  1. When configuring a dual-stack cluster, the user must specify both `--node-cidr-mask-size-ipv4` and `--node-cidr-mask-size-ipv6` to set the per-node IP mask sizes, instead of the previous `--node-cidr-mask-size` flag.
  2. The `--node-cidr-mask-size` flag is mutually exclusive with `--node-cidr-mask-size-ipv4` and `--node-cidr-mask-size-ipv6`.

New alpha features include:
* Online volume resizing will increase the filesystem size of a resized volume without requiring a Pod restart.

### Documentation

- Promoted the `--chunk-size` flag to stable. The kubectl `describe`, `get`, `drain`, and `events` commands can use `--chunk-size` flag to set chunk size. ([#134481](https://github.com/kubernetes/kubernetes/pull/134481), [@soltysh](https://github.com/soltysh))

### Bug or Regression

* The following deprecated flags were removed from `kube-controller-manager`:

  * `replication-controller-lookup-cache-size`
  * `replicaset-lookup-cache-size`
  * `daemonset-lookup-cache-size`

  Don't use these flags. Using deprecated flags causes the server to print a warning. Using a removed flag causes the server to abort the startup.

* increase grpc client default response size ([#63977](https://github.com/kubernetes/kubernetes/pull/63977), [@runcom](https://github.com/runcom))
* Increase the gRPC max message size to 16MB in the remote container runtime. ([#64672](https://github.com/kubernetes/kubernetes/pull/64672), [@mcluseau](https://github.com/mcluseau))

- Register/Deregister Targets in chunks for AWS TargetGroup ([#101592](https://github.com/kubernetes/kubernetes/pull/101592), [@M00nF1sh](https://github.com/M00nF1sh)) [SIG Cloud Provider]

*   [beta] Flag `--chunk-size={SIZE}` is added to `kubectl get` to customize the number of results returned in large lists of resources. This reduces the perceived latency of managing large clusters because the server returns the first set of results to the client much more quickly....
