* kube-up: increase download timeout for kubernetes.tar.gz ([#29426](https://github.com/kubernetes/kubernetes/pull/29426), [@justinsb](https://github.com/justinsb))
* Fix RBAC authorizer of ServiceAccount ([#29071](https://github.com/kubernetes/kubernetes/pull/29071), [@albatross0](https://github.com/albatross0))

  Similarly you can also access  kubelet's `/pods` endpoint to fetch a list of Pods bound to that node by granting the caller `nodes/pods` permission in RBAC.
  Similarly you can also access kubelet's `/configz` endpoint to fetch kubelet's configuration by granting the caller `nodes/configz` permission in RBAC.

 - `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 init phase kubeconfig...

- Fixed a regression preventing garbage collection of RBAC role and binding objects ([#90534](https://github.com/kubernetes/kubernetes/pull/90534), [@apelisse](https://github.com/apelisse)) [SIG Auth]

- Kubeadm: avoided uploading a defaulted flag value "--authorization-mode=Node,RBAC" for the kube-apiserver in the ClusterConfiguration stored in the "kube-system/kubeadm-config" ConfigMap. "Node,RBAC" are already the kubeadm defaults for this flag, so this action is redundant. ([#123555](https://github.com/kubernetes/kubernetes/pull/123555), [@neolit123](https://github.com/neolit123))

- Kube-apiserver: The `rbac.authorization.k8s.io/v1alpha1` API version is removed; use the `rbac.authorization.k8s.io/v1` API, available since v1.8. The `scheduling.k8s.io/v1alpha1` API version is removed; use the `scheduling.k8s.io/v1` API, available since v1.14. ([#104248](https://github.com/kubernetes/kube...

* Reverted conversion of influx-db to Pet Set, it is now a Replication Controller. ([#30080](https://github.com/kubernetes/kubernetes/pull/30080), [@jszczepkowski](https://github.com/jszczepkowski))
* rbac validation: rules can't combine non-resource URLs and regular resources ([#29930](https://github.com/kubernetes/kubernetes/pull/29930), [@ericchiang](https://github.com/ericchiang))

Beta and enabled the feature by default. This implies that 1) for new clusters kubeadm will start using the `kube-system/kubelet-config` naming scheme for the kubelet ConfigMap and RBAC rules, instead of the legacy `kubelet-config-x.yy` naming. 2) during upgrade, kubeadm will only write the new scheme ConfigMap and RBAC objects. To disable the feature you can pass `UnversionedKubeletConfigMap: false` in the kubeadm config for new clusters. For upgrade on existing clusters you can also override the...
