bitset Changelog

Here you can see the full list of changes between each bitset release.

Version 1.4.8

• Add support for GHC 7.8
• IsList instance for BitSet, so it's possible to use OverloadedLists extension.

Version 1.4.7

Released on August 25th, 2013

• 'GBitSet' was renamed to 'BitSet' and is now 'newtype' as suggested by John Ericson, see #10 on GitHub for details.

Version 1.4.6

Released on July 17th, 2013

• Fixed build issues on Windows, see #9 on GitHub for details.

Version 1.4.5

Released on June 6th, 2013

• Fixed 'Ord' instance, same bug as in 'Eq'. Where is my mind?

Version 1.4.4

Released on May 14th, 2013

• Fixed 'Eq' instance, equal sizes don't mean a thing!

Version 1.4.3

Released on May 13th, 2013

• Fixed bug with broken cabal distribution.

Version 1.4.2

• Switched to GMP bit fiddling functions, the corresponding patch for 'integer-gmp' was submitted to GHC, see http://hackage.haskell.org/trac/ghc/ticket/7860

Version 1.4.1

Released on April 24th, 2013

• Removed 'clearBitInteger' which didn't update the size field of the newly created 'Integer'. Turns out it's completely non-trivial to implement.

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
