  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`.

- `-- 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.

  PodSubnet validates against the corresponding cluster "--node-cidr-mask-size" of the kube-controller-manager, it fail if the values are not compatible.
  kubeadm no longer sets the node-mask automatically on IPv6 deployments, you must check that your IPv6 service subnet mask is compatible with the default node mask /64 or set it accordingly.

- Fixed a bug that caused the `apiserver` to panic when trying to allocate a Service with a dynamic `ClusterIP` and was configured with Service CIDRs with a /28 mask for IPv4 and a /124 mask for IPv6 ([#115322](https://github.com/kubernetes/kubernetes/pull/115322), [@aojea](https://github.com/aojea))
- Fixed a bug where Kubernetes would apply a default StorageClass to a PersistentVolumeClaim,

- Kubeadm: skip validating pod subnet against node-cidr-mask when allocate-node-cidrs is set to be false ([#98984](https://github.com/kubernetes/kubernetes/pull/98984), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]

- Node labels `beta.kubernetes.io/metadata-proxy-ready`, `beta.kubernetes.io/metadata-proxy-ready` and `beta.kubernetes.io/kube-proxy-ds-ready` are no longer added on new nodes.
  - ip-mask-agent addon starts to use the label `node.kubernetes.io/masq-agent-ds-ready` instead of `beta.kubernetes.io/masq-agent-ds-ready` as its node selector.
