ANN: Tribool 0.6.2 Released

[Grant Jenks]

Announcing the Release of Tribool Version 0.6.2

What is Tribool?
----------------

Tribool is an Apache2 licensed module for three-valued logic. More commonly
found in SQL, three-valued logic defines truth tables over the values True,
False, and Indeterminate. The third value is considered a state being one of
True or False. Tribool implements logical operators on these values as
immutable singletons. The implementation is pure-Python with 100% code coverage
and complete documentation.

What's new in 0.6.2?
--------------------

- Implemented __copy__ and __deepcopy__ methods as part of `copy` module
  protocol.
- Implemented __reduce__ as part of `pickle` module protocol.
- Changed subclassing from `object` to `tuple` to prevent mutation of internal
  state.
