+### Features
+
+* **build:** optionally build an ES2015 distro ([#13471](https://github.com/angular/angular/issues/13471)) ([be6c95a](https://github.com/angular/angular/commit/be6c95a))

+
+
+### BREAKING CHANGES
+
+* core: - Because `injector.get()` is now parameterize it is possible that code
+  which used to work no longer type checks. Example would be if one
+  injects `Foo` but configures it as `{provide: Foo, useClass: MockFoo}`.
+  The injection instance will be that of `MockFoo` but the type will be
+  `Foo` instead of `any` as in the past. This means that it was possible
+  to call a method on `MockFoo` in the past which now will fail type
+  check. See this example:
+
+```
+class Foo {}
+class MockFoo extends Foo {
+  setupMock();
+}
+
+var PROVIDERS = [
+  {provide: Foo, useClass: MockFoo}
+];
+
+...
+
+function myTest(injector: Injector) {
+  var foo = injector.get(Foo);
+  // This line used to work since `foo` used to be `any` before this
+  // change, it will now be `Foo`, and `Foo` does not have `setUpMock()`.
+  // The fix is to downcast: `injector.get(Foo) as MockFoo`.
+  foo.setUpMock();
+}
+```
