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(); } ``` ## [2.4.5](https://github.com/angular/angular/compare/2.4.4...2.4.5) (2017-01-25) ### Bug Fixes * **compiler:** [i18n] XMB/XTB placeholder names can contain only A-Z, 0-9, _n ([5492fad](https://github.com/angular/angular/commit/5492fad)) * **compiler:** fix regexp to support firefox 31 ([#14082](https://github.com/angular/angular/issues/14082)) ([bd2eecb](https://github.com/angular/angular/commit/bd2eecb)), closes [#14029](https://github.com/angular/angular/issues/14029) [#13900](https://github.com/angular/angular/issues/13900) * **core:** export animation classes required for Renderer impl ([#14002](https://github.com/angular/angular/issues/14002)) ([fd4f9ac](https://github.com/angular/angular/commit/fd4f9ac)), closes [#14001](https://github.com/angular/angular/issues/14001) * **upgrade:** ensure upgraded injector is initialized early enough ([#14065](https://github.com/angular/angular/issues/14065)) ([3b2fb23](https://github.com/angular/angular/commit/3b2fb23)), closes [#13811](https://github.com/angular/angular/issues/13811) # [4.0.0-beta.4](https://github.com/angular/angular/compare/4.0.0-beta.3...4.0.0-beta.4) (2017-01-19) ### Bug Fixes * **animations:** fix internal jscompiler issue and AOT quoting ([#13798](https://github.com/angular/angular/issues/13798)) ([c2aa981](https://github.com/angular/angular/commit/c2aa981)) * **common:** support numeric value as discrete cases for NgPlural ([#13876](https://github.com/angular/angular/issues/13876)) ([f364557](https://github.com/angular/angular/commit/f364557)) * **http:** don't create a blob out of ArrayBuffer when type is application/octet-stream ([#13992](https://github.com/angular/angular/issues/13992)) ([1200cf2](https://github.com/angular/angular/commit/1200cf2)), closes [#13973](https://github.com/angular/angular/issues/13973) * **router:** enable loadChildren with function in aot ([#13909](https://github.com/angular/angular/issues/13909)) ([635bf02](https://github.com/angular/angular/commit/635bf02)), closes [#11075](https://github.com/angular/angular/issues/11075) * **router:** routerLinkActive should not throw when not initialized ([#13273](https://github.com/angular/angular/issues/13273)) ([e8ea741](https://github.com/angular/angular/commit/e8ea741)), closes [#13270](https://github.com/angular/angular/issues/13270) * **security:** allow calc and gradient functions.
