Deprecation warnings can no longer be disabled. Class templates now allow super-classes to be defined as template arguments. This release adds the all_raise_py_exception argument to the %Module directive, the /NoRaisesPyException/ function annotation, the /PyName/ typedef annotation, support for "public" preceding the name of a class in a super-class list, and support for "protected" and "private" preceding the name of a class in a super-class list (any such super-class will be ignored).
