* "t#" format has been removed: use "s#" or "s*" instead
* "w" and "w#" formats has been removed: use "w*" instead

+ opaque C pointers in Python objects, the :ctype:`PyCapsule` API should be
+ used instead; the new type has a well defined interface for passing typing
+ safety information and a less complicated signature for calling a destructor.
