* kubefed init creates a service account for federation controller manager in the federation-system namespace and binds that service account to the federation-system:federation-controller-manager role that has read and list access on secrets in the federation-system namespace.

### **Cluster Federation**
#### Placement Policy
* [alpha] The federation-apiserver now supports a SchedulingPolicy admission controller that enables policy-based control over placement of federated resources. For more information, see [Set up placement policies in Federation](https://kubernetes.io/docs/tasks/federation/set-up-placement-policies-federation/).

#### Cluster Selection

management (beyond our initial Federation approach), and preparing
to release Federation for general availability ('GA').

[SIG Multi-cluster]: https://github.com/kubernetes/community/tree/master/sig-federation

### SIG Node

[SIG Node][] is responsible for the components that support the controlled
interactions between pods and host resources, and manage the lifecycle
of pods scheduled on a node.

*   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

  -  The federation plugin (allows for v1 Kubernetes federation) has been removed.

### SIG Multicluster

* Fix OpenAPI/JSON Schema generation for two functions with the same name (in different modules) with the same composite bodies.
    * Composite bodies' IDs are now based on path, not only on route name, as the auto-generated name uses the function names, that can be duplicated in different modules.
    * The same new ID generation applies to response models.

### Bug or Regression

- Expose --applyconfig-openapi-schema flag for client generation and fix applyconfig-gen to not create import cycles ([#124371](https://github.com/kubernetes/kubernetes/pull/124371), [@soltysh](https://github.com/soltysh)) [SIG API Machinery]

- Restore --verify-only function in code generation wrappers. ([#123261](https://github.com/kubernetes/kubernetes/pull/123261), [@skitt](https://github.com/skitt)) [SIG API Machinery]

- Fixes conversion error in multi-version custom resources that could cause metadata.generation to increment on no-op patches or updates of a custom resource. ([#88995](https://github.com/kubernetes/kubernetes/pull/88995), [@liggitt](https://github.com/liggitt)) [SIG API Machinery]
