Passing parameters between routes in Ember 2.x

While going from one route to another, I want to pass some data (especcially arrays). How is it possible?

Why can't we use query-params with arrays?

Is it a problem storing data in a specific service during transition?

Note: I know there are some old questions those are nearly the same with this question. But their selected answers are no more applicable for Ember 2.x. Those questions are: 1, 2.
