- Kube-apiserver: redirect responses are no longer returned from backends by default. Set `--aggregator-reject-forwarding-redirect=false` to continue forwarding redirect responses. ([#112330](https://github.com/kubernetes/kubernetes/pull/112330), [@enj](https://github.com/enj)) [SIG API Machinery]

## Dependencies

*   The `/ui` redirect in kube-apiserver is deprecated and will be removed in Kubernetes 1.10. ([#53046](https://github.com/kubernetes/kubernetes/pull/53046), [@maciaszczykm](https://github.com/maciaszczykm))

- Kube-apiserver: redirect responses are no longer returned from backends by default. Set `--aggregator-reject-forwarding-redirect=false` to continue forwarding redirect responses. ([#112331](https://github.com/kubernetes/kubernetes/pull/112331), [@enj](https://github.com/enj)) [SIG API Machinery]

- client-go releases will no longer have bootstrap (k8s.io/client-go/tools/bootstrap) related code. Any reference to it will break. Please redirect all references to k8s.io/bootstrap instead. ([#67356](https://github.com/kubernetes/kubernetes/pull/67356), [@yliaog](https://github.com/yliaog))

* Add OAuth2 redirect page for Swagger UI. This allows having delegated authentication in the Swagger UI docs. For this to work, you need to add `{your_origin}/docs/oauth2-redirect` to the allowed callbacks in your OAuth2 provider (in Auth0, Facebook, Google, etc).
    * For example, during development, it could be `http://localhost:8000/docs/oauth2-redirect`.
