+- The "optimization opportunity" message when importing the server-side `react-on-rails` instead of `react-on-rails/client` in browsers is now a warning for two reasons:
+  - Make it more prominent
+  - Include a stack trace when clicked
+  - [PR 1706](https://github.com/shakacode/react_on_rails/pull/1706) by [alexeyr-ci](https://github.com/alexeyr-ci).
