Not much. We got a new type of Family Template, what they call the 'two pick' template. This allows you to make Families that are kinda like Revit 8's beams, in that you can draw or pick a line within the model and have that be the basis for your Family's creation.
I just used this last week to make some nice sloped architectural parametric columns. It could also be used like a 3D repeating detail tool, for you can tie parametric arrays to the length of the drawn/picked line.
Other than that, I can't think of anything huge. Some small stuff, sure, but nothing like the Shared families added in R8.
