CarrouselView, what happened?

I read some posts about Xamarin.Forms.CarouselView, but this still in pre-release state "2.3.0-pre2".
In some forum thread I read that the project moved to https://github.com/alexrainman/CarouselView with the possibility of merging into Xamarin.Forms.
Has been merged already at this version (Xamarin.Forms 3.5)?? . If not, Is there any plans soon?
