- EndpointSlice API is now GA. The EndpointSlice topology field has been removed from the GA API and will be replaced by a new per Endpoint Zone field. If the topology field was previously...

"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...

* [GCP kube-up.sh] Variables that were part of kube-env that were only used for kubelet flags are no longer being set, and are being replaced by the more portable mechanism of the kubelet configuration file. The individual variables in the kube-env metadata entry were never meant to be a stable interface and this release note only applies if you are depending on them. ([#60020](https:...

- 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
	// NetworkAttachmentDefinition resource is deployed to the cluster to allow the istio-cni plugin to be
	// 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))
