History

1.2.0 (2017-03-05) ^^^^^^^^^^^^^^^^^^

• To improve readability, do not test the examples in the documentation with Python 2.6.
• Code pathways that are specific to one Python version are marked with # pragma directives, and the collection of coverage statistics ignores them as appropriate.
• Add support for Python 3.6.
• Implement #11_: Take the absolute value of an interval.
• Provide a helpful message during installation if setuptools is outdated (#13_).
