As mentioned by others, we've dropped trigraph and deprecated rand (and offer an alternative). I also have:

* p2809 Trivial infinite loops are not Undefined Behavior * p1152 Deprecating volatile * p0907 Signed Integers are Two's Complement * p2723 Zero-initialize objects of automatic storage duration * p2186 Removing Garbage Collection Support

So it is possible to change things!
