+### BREAKING CHANGES
+
+* there's a chance of breakage as router's Instruction constructor
+  signature changed.
+
+* `Renderer.listen` now has to return a function that
+  removes the event listener.
+
+* remove TemplateRef.elementRef setter
+
+* Tests are now required to use `setBaseTestProviders`
+to set up. Assuming your tests are run on a browser, setup would change
+as follows.
+Before:
+```js
+// Somewhere in test setup
+import {BrowserDomAdapter} from 'angular2/src/platform/browser/browser_adapter';
+BrowserDomAdapter.makeCurrent
+```
+After:
+```js
+// Somewhere in the test setup
+import {setBaseTestProviders} from 'angular2/testing';
+import {
+  TEST_BROWSER_PLATFORM_PROVIDERS,
+  TEST_BROWSER_APPLICATION_PROVIDERS
+} from 'angular2/platform/testing/browser';
+setBaseTestProviders(TEST_BROWSER_PLATFORM_PROVIDERS,
+                     TEST_BROWSER_APPLICATION_PROVIDERS);
+```
+
+* This is very unlikely to be breaking, but I'm still marking just in case. The only change to the user should be that dev mode is driven by Dart's checked mode, like it was in the past.
