Lawrence already noted that this is already covered by the What's New document (semantically, it's identical to omitting the parentheses entirely). As for the reason: it makes it possible to use the same style for classes without bases as is used for functions without arguments. Prior to this change, there was a sharp break in the class syntax, such that if you got rid of the last base class you had to get rid of the parentheses as well.
