Hi,
Yes they are. But because Variable what so widely used by the users, we are leaving it for now.
It is only a no-op that gives you a Tensor right now.
But for deprecation:

We just removed old style autograd.Function code: they will be actual errors in 1.5
We are removing .data internally to prepare for adding warning and deleting it (or making it a no-op like Variable is right now)
