-----------------

* support for loading binary Lua modules on systems that support it

-----------------

* relicensed to the MIT license used by LuaJIT2 to simplify licensing
considerations

-------------------

* fix Cython generated C file using Cython 0.13

-----------------

* fixed undefined behaviour on ``str(lua_object)`` when the object's
``__tostring()`` meta method fails

* removed redundant "error:" prefix from ``LuaError`` messages

* access to Python's ``python.builtins`` from Lua code

* more generic wrapping rules for Python objects based on supported
protocols (callable, getitem, getattr)

* new helper functions ``as_attrgetter()`` and ``as_itemgetter()`` to
specify the Python object protocol used by Lua indexing when
wrapping Python objects in Python code

* new helper functions ``python.as_attrgetter()``,
``python.as_itemgetter()`` and ``python.as_function()`` to specify
the Python object protocol used by Lua indexing of Python objects in
Lua code

* item and attribute access for Python objects from Lua code

-----------------

* fix Lua stack leak during table iteration

* fix lost Lua object reference after iteration

-----------------

* error reporting on Lua syntax errors failed to clean up the stack so
that errors could leak into the next Lua run

* Lua error messages were not properly decoded
