I am pretty sure that changes have been made to the "con" system as well.
In beta - things appeared to either be blue, red, green, orange etc. Now, each colour has variations of shape to give you a more accurate idea. This is more detailed than the "red with 3 horns" system. each colour appears to have either one, two, three or no "horns".
Keyboard and mouse play is great. Nowhere near as frustrating as in beta!
