Static Analyzer
---------------
...
- The static analyzer now supports using the
`z3 theorem prover <https://github.com/z3prover/z3>`_ from Microsoft Research
as an external constraint solver. This allows reasoning over more complex
queries, but performance is ~15x slower than the default range-based
constraint solver. To enable the z3 solver backend, clang must be built with
the ``CLANG_ANALYZER_BUILD_Z3=ON`` option, and the
``-Xanalyzer -analyzer-constraints=z3`` arguments passed at runtime.
Undefined Behavior Sanitizer (UBSan)

Python Binding Changes
----------------------
Python bindings now support both Python 2 and Python 3.
The following methods have been added:
- ``is_scoped_enum`` has been added to ``Cursor``.
- ``exception_specification_kind`` has been added to ``Cursor``.
- ``get_address_space`` has been added to ``Type``.
- ``get_typedef_name`` has been added to ``Type``.
- ``get_exception_specification_kind`` has been added to ``Type``.
