+
+### BREAKING CHANGES
+
+- `angular2/test_lib` is now called `angular2/testing`
+  - `test_lib.js` -> `testing.js`
+  - `import {...} from 'angular2/test_lib'` -> `import {...} from 'angular2/testing'`
+- [()] desugaring changed:
+
+  Before:
+  ```
+  <cmp [(prop)]="field"> was desugared to <cmp [prop]="field" (prop)="field=$event">
+  ```
+  After:
+  ```
+  <cmp [(prop)]="field"> is desugared to <cmp [prop]="field" (prop-change)="field=$event">
+  ```
+
+
+### API DEPRECATION
+
+- "DI Binding" terminology has changed to "DI Providers" to avoid conflicts/confusion with data-binding. All commonly used apis that use "bind" or "binding" in the name still work but are deprecated and will be removed in future alpha releases. Please update your code:
+  - `bind` -> `provide`
+  - `@Component(bindings: ...)` -> `@Component(providers: ...)`
+  - `@Component(viewBindings: ...)` -> `@Component(viewProviders: ...)`
+  - `HTTP_BINDINGS` -> `HTTP_PROVIDERS`
+  - `JSONP_BINDINGS` -> `JSONP_PROVIDERS`
+  - `ROUTER_BINDINGS` -> `ROUTER_PROVIDERS`
+  - `FORM_BINDINGS` -> `FORM_PROVIDERS`
+  - `ELEMENT_PROBE_BINDINGS` -> `ELEMENT_PROBE_PROVIDERS`
+  - `NoBindingError` -> `NoProviderError`
+  - `AbstractBindingError` -> `AbstractProviderError`
+  - `InvalidBindingError` -> `InvalidProviderError`
+  - `beforeEachBindings` -> `beforeEachProviders`
+  - `Binding` -> `Provider`
