Note about the addition of `beforeEach(fakeAsync(inject(…))))` in some tests: `ApplicationRef` is now using `ngOnDestroy` and there is eager, including all of its dependencies which contain `NgZone`. The additional `fakeAsync` in `beforeEach` ensures that `NgZone` uses the fake async zone as parent, and not the root zone. BREAKING CHANGE (via deprecations): - `ApplicationRef.dispose` is deprecated. Destroy the module that was created during bootstrap instead by calling `NgModuleRef.destroy`. - `AplicationRef.registerDisposeListener` is deprecated. Use the `ngOnDestroy` lifecycle hook for providers or `NgModuleRef.onDestroy` instead. - `disposePlatform` is deprecated. Use `destroyPlatform` instead. - `PlatformRef.dipose()` is deprecated. Use `PlatformRef.destroy()` instead. - `PlatformRef.registerDisposeListener` is deprecated. Use `PlatformRef.onDestroy` instead. - `PlaformRef.diposed` is deprecated. Use `PlatformRef.destroyed` instead.
