+All :mod:`ctypes` data types now support
+:meth:`from_buffer` and :meth:`from_buffer_copy`
+methods that create a ctypes instance based on a
+provided buffer object.  :meth:`from_buffer_copy` copies
+the contents of the object,
+while :meth:`from_buffer` will share the same memory area.

 A new calling convention tells :mod:`ctypes` to clear the ``errno`` or
 Win32 LastError variables at the outset of each wrapped call.
