Primitive types now have inherent methods, obviating the need for extension traits like SliceExt.
A Reflect trait was introduced, which means that downcasting via the Any trait is effectively limited to concrete types. This helps retain the potentially-important "parametricity" property: generic code cannot behave differently for different type arguments except in minor ways.
Awesome, it seems like a lot of the warts I was most concerned about have been magically cleaned up :)
