1.4.1
=====

Py3: added Enum creation flags: Auto, MultiValue, NoAlias, Unique

fixed extend_enum to honor Enum flags


1.4.0
=====

When possible aenum inherits from Python's own enum.

Breaking change: enum members now default to evaluating as True to maintain
compatibility with the stdlib.

Add your own __bool__ (__nonzero__ in Python 2) if need this behavior:

    def __bool__(self):
        return bool(self.value)
    __nonzero__ = __bool__
