Angular4 AoT suppport

Could you add a tag with Angular4 dependencies?
I see it was updated to 5 in November.

I don't think there should be any issues.
It's working with webpack JiT build on Angular4.
But crashing with AoT compiler due to:
> Metadata version mismatch, found version 4, expected 3

I think just downgrading of dependencies in package.json should do it
