"x-kubernetes-list-type annotates an array to further describe its topology. This extension must only be used on lists and may have 3 possible values:\n\n1) `atomic`: the list is treated as a single entity, like a scalar.\n     Atomic lists will be entirely replaced when updated. This extension\n     may be used on any type of list (struct, scalar, ...).\n2) `set`:\n     Sets are lists that must not have multiple items with the same value. Each\n     value must be a scalar, an object with x-kubernetes-map-type...

- Some apiserver metrics were changed, as follows.
  - `priority_level_seat_count_samples` is replaced with `priority_level_seat_utilization`, which samples every nanosecond rather than every millisecond; the old metric conveyed utilization despite its name.
  - `priority_level_seat_count_watermarks` is removed.

	// Specifies the CNI provider. Can be either "default" or "multus". When set to "multus", an additional

	// invoked in a cluster using the Multus CNI plugin.

* The metrics APIs, `custom-metrics.metrics.k8s.io` and `metrics`, were moved from `v1alpha1` to `v1beta1`, and renamed to `custom.metrics.k8s.io` and `metrics.k8s.io`, respectively. If you have deployed a custom metrics adapter, ensure that it supports the new API version. If you have deployed Heapster in aggregated API server mode, upgrade Heapster to support the latest API version.

 - `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...

- Removed the following deprecated metrics:
  - node_collector_evictions_number replaced by node_collector_evictions_total
  - scheduler_e2e_scheduling_duration_seconds replaced by scheduler_scheduling_attempt_duration_seconds ([#115209](https://github.com/kubernetes/kubernetes/pull/115209), [@dgrisonnet](https://github.com/dgrisonnet))
