* ``make_iterator()`` improvements for better compatibility with various types
(now uses prefix increment operator)
* ``arg()`` now accepts a wider range of argument types for default values
+* Added ``repr()`` method to the ``handle`` class.
* Added support for registering structured dtypes via ``PYBIND11_NUMPY_DTYPE()`` macro.
* Added ``PYBIND11_STR_TYPE`` macro which maps to the ``builtins.str`` type.
* Added a simplified ``buffer_info`` constructor for 1-dimensional buffers.
