Changelog for bitset-1.4.0

bitset Changelog ================ Here you can see the full list of changes between each bitset release. Version 1.4.0 ------------- Released on April 4th, 2013 - More speed optimizations, 'Data.BitSet.Dynamic' is close to 'Data.Set' performance on most operations. - Added 'Data.BitSet.Word', a bit set with native integer as container type, significantly faster then 'Data.Set' for enumerated types with small number of constructors. - Added folds, 'map' and 'filter' for consistency with other Haskell containers. Version 1.3.0 ------------- Released on March 25th, 2013 - Added a generic bit set data type, abstract with respect to the underlying container. - Improved dynamic bit set performance via optimized 'popCount' and 'testBit' functions. Version 1.2 ----------- Initial release, released on March 22th, 2013
