+++++++++++++++++++ - A small release. Some bug fixes. - Remove Python 3.3 support. Python 3.3 support has been dropped by the Python foundation. - Default environments are now using the same Python version as the Python process. In 0.12.x, we used to load the latest Python version on the system. - Added ``include_builtins`` as a parameter to usages. - ``goto_assignments`` has a new ``follow_builtin_imports`` parameter that changes the previous behavior slightly.
