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

### SIG Multicluster

* 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.

- `kubectl wait` ensures that observedGeneration >= generation to prevent stale state reporting. An example scenario can be found on CRD updates. ([#97408](https://github.com/kubernetes/kubernetes/pull/97408), [@KnicKnic](https://github.com/KnicKnic))

### Documentation

- The go version defined in `.go-version` is now fetched when invoking test, build, and code generation targets if the current go version does not match it. Set $FORCE_HOST_GO=y while testing or building to skip this behavior, or set $GO_VERSION to override the selected go version. ([#115377](https://github.com/kubernetes/kubernetes/pull/115377),...

* Fix Heapster configuration and Metrics Server configuration to enable overriding default resource requirements. ([#56965](https://github.com/kubernetes/kubernetes/pull/56965), [@kawych](https://github.com/kawych))

* Improved event generation in volume mount, attach, and extend operations ([#56872](https://github.com/kubernetes/kubernetes/pull/56872), [@davidz627](https://github.com/davidz627))

- 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]

* Restrict redirect following from the apiserver to same-host redirects, and ignore redirects in some cases. ([#66516](https://github.com/kubernetes/kubernetes/pull/66516), [@tallclair](https://github.com/tallclair))
* Enable insertId generation, and update Stackdriver Logging Agent image to 0.5-1.5.36-1-k8s. This help reduce log duplication and guarantee log order. ([#68920](https://github.com/kubernetes/kubernetes/pull/68920), [@qingling128](https://github.com/qingling128))
