bitset-1.1: CHANGES

-*- mode: outline -*-

* 1.1
Added conversion to and from the underlying Integral value (thanks to Mathieu
Boespflug).

* 1.0
Instead of a custom Hash typeclass, we now use Enum.  It's standard and it gives
us exactly what we need, so it's a win-win.

Also, use unboxed tuples to represent the bitset.
