- `kubeadm`: a separate "super-admin.conf" file is now deployed. The User in `admin.conf` is now bound to a new RBAC Group `kubeadm:cluster-admins` that has `cluster-admin` `ClusterRole` access. The User in `super-admin.conf` is now bound to the `system:masters` built-in super-powers / break-glass Group that can bypass RBAC. Before this change, the default `admin.conf` was bound to `system:masters` Group, which was undesired. Executing `kubeadm...

- Deprecate the default service IP CIDR. The previous default was `10.0.0.0/24` which will be removed in 6 months/2 releases. Cluster admins must specify their own desired value, by using `--service-cluster-ip-range` on kube-apiserver.

	* Mechanism of adding `federation domain maps` to kube-dns deployment via `--federations` flag is superseded by adding/updating `federations` key in `kube-system/kube-dns` configmap. If user is using kubefed tool to join cluster federation, adding federation domain maps to kube-dns is already taken care by `kubefed join` and does not need further action.

There is no mitigation from this issue.  Cluster admins should take care to secure aggregated API servers and should not grant access to mutate `APIService`s to untrusted parties.

**Affected Versions**:
  - kube-apiserver v1.25.0
  - kube-apiserver v1.24.0 - v1.24.4

* GCE: Fixed for internal load balancer management resulting in backend services with outdated instance group links. ([#62885](https://github.com/kubernetes/kubernetes/pull/62885), [@nicksardo](https://github.com/nicksardo))

- CSIServiceAccountToken graduates to Beta and enabled by default. ([#99298](https://github.com/kubernetes/kubernetes/pull/99298), [@zshihang](https://github.com/zshihang))

* kube-up.sh on GCE now includes the bootstrap admin in the super-user group, and ensures the auth token file is correct on upgrades ([#39537](https://github.com/kubernetes/kubernetes/pull/39537), [@liggitt](https://github.com/liggitt))
