  +### Features
  +
  +* UI must be created before first render, drainMicroTasks when the first page is created.
  +This removes the white screen displayed between the launch screen and the initial page view.
  +Speeds up roughly 300ms startup times for iOS with Angular. ([#1103](https://github.com/NativeScript/nativescript-angular/pull/1103))
  +
  +
  +* update to Angular 5 animations and add support for AnimationBuilder ([#1114](https://github.com/NativeScript/nativescript-angular/issues/1114)) ([191f2a0](https://github.com/NativeScript/nativescript-angular/commit/191f2a0))
  +
