### **Multicluster**

*   Development of Kubernetes Federation has moved to [github.com/kubernetes/federation](https://github.com/kubernetes/federation). This move out of tree also means that Federation will begin releasing separately from Kubernetes. Impact:
    *   Federation-specific behavior will no longer be included in kubectl
    *   kubefed will no longer be released as part of Kubernetes

 - [Action Required] CSI drivers that call IsLikelyNotMountPoint should not assume false means that the path is a mount point. Each CSI driver needs to make sure correct usage of return value of IsLikelyNotMountPoint because if the file is an irregular file but not a mount point is acceptable ([#129370](https://github.com/kubernetes/kubernetes/pull/129370),...

- Introduce a feature gate `DisableCloudProviders` allowing to disable cloud-provider initialization in KAPI, KCM and kubelet.

#### Other API changes:
- The beta feature `ServerSideApply` enables tracking and managing changed fields for all new objects, which means there will be `managedFields` in `metadata` with the list of managers and their owned fields.

  qualified domain name (FQDN) of a Pod is set as hostname of its containers. 
  In Linux containers, this means setting the FQDN in the hostname field of the 
  kernel (the nodename field of struct utsname).  In Windows containers, this
  means setting the this means setting the registry value of hostname for the registry key HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters to FQDN.

                    /* Technically we should also try to authenticate here but that means doing the session setup and tree connect separately. For now a simple connect will at least tell us if the host is alive. That should be sufficient for 99% of the cases. We can revisit this again for 2.0.

This means that now, if you set a value in a context variable before `yield`, the value would still be available after `yield` (as you would intuitively expect). And it also means that you can reset the context variable with a token afterwards.

For example, this works correctly now:

```Python
