OS X Yosemite 10.10.2. Dock Appearance

I just installed the latest update, OS X Yosemite 10.10.2.

I think there may be a difference with the appearance of my dock- I can't quite put my finger on it- maybe it used to be transparent and now no longer is?
Anyone else notice a change?

I don't really like the new look of the dock. 😟
