- Health check (liveness & readiness) probes using an HTTPGetAction will no longer follow redirects to different hostnames from the original probe request. Instead, these non-local redirects will be treated as a Success (the documented behavior). In this case an event with reason "ProbeWarning" will be generated, indicating that the redirect was ignored. If you were previously relying on the redirect to run health checks against different endpoints, you will need to perform the healthcheck logic...

* 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`.

*   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))

* Restores redirect behavior for proxy subresources ([#52933](https://github.com/kubernetes/kubernetes/pull/52933), [@liggitt](https://github.com/liggitt))
