 # Change Log
 All notable changes to this project will be documented in this file. Items under `Unreleased` is upcoming features that will be out in next version.
 
+## v2.0.0
+- Move JavaScript part of react_on_rails to npm package 'react-on-rails'.
+- Converted JavaScript code to ES6! with tests!
+- No global namespace pollution. ReactOnRails is the only global added.
+- New API. Instead of placing React components on the global namespace, you instead call ReactOnRails.register, passing an object where keys are the names of your components.
+  ```
+  import ReactOnRails from 'react-on-rails';
+  ReactOnRails.registerComponent({name: component});
+  ```
+  Best done with Object destructing
+  ```
+  import ReactOnRails from 'react-on-rails';
+  ReactOnRails.registerComponent(
+    {
+      Component1,
+      Component2
+    }
+  );
+  ```
+  Previously, you used 
+  ```
+  window.Component1 = Component1;
+  window.Component2 = Component2;
+  ```
+  This would pollute the global namespace. See details in the README.md for more information.
+- Your jade template for the WebpackDevServer setup should use the new API:
+  ```
+  ReactOnRails.render(componentName, props, domNodeId);
+  ```
+  such as:
+  ```
+  ReactOnRails.render("HelloWorldApp", {name: "Stranger"}, 'app');
+  ```
+- All npm dependency libraries updated. Most notable is going to Babel 6.
+- Dropped support for react 0.13.
+- JS Linter uses ShakaCode JavaScript style: https://github.com/shakacode/style-guide-javascript 
+- Generators account these differences.
+
