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
