- Multiple Kubernetes clusters can now share the same resource group
    - When upgrading from previous releases, issues will arise with public IPs if multiple clusters share the same resource group. To solve these problems, make the following changes to the cluster:

### Failing Test

- Kubelet: the HostPort implementation in dockershim was not taking into consideration the HostIP field, causing that the same HostPort can not be used with different IP addresses.

- `oc describe quota` used has the same unit format as hard ([#102177](https://github.com/kubernetes/kubernetes/pull/102177),...

* Add note to docs: [Include the same router multiple times with different `prefix`](https://fastapi.tiangolo.com/tutorial/bigger-applications/#include-the-same-router-multiple-times-with-different-prefix). PR [#348](https://github.com/tiangolo/fastapi/pull/348).

* Fix OpenAPI/JSON Schema generation for two functions with the same name (in different modules) with the same composite bodies.

* Ensure orphan public IPs on Azure deleted when service recreated with the same name. ([#70463](https://github.com/kubernetes/kubernetes/pull/70463), [@feiskyer](https://github.com/feiskyer))

// validatePathNoBacksteps makes sure the targetPath does not have any `..` path elements when split
//
// This assumes the OS of the apiserver and the nodes are the same. The same check should be done
// on the node to ensure there are no backsteps.

- When a CNI plugin returns dual-stack pod IPs, kubelet will now try to respect the
  "primary IP family" of the cluster by picking a primary pod IP of the same family

### Feature

- 'Added selector validation to `HorizontalPodAutoscaler`: when multiple HPAs
  select the same set of Pods, scaling now will be disabled for those HPAs with
  the reason `AmbiguousSelector`. This change also covers a case when multiple HPAs
  point to the same deployment.'
