ANN: vector 0.5

Hi everyone, I am pleased to announce the release of version 0.5 of package vector, a high-performance Haskell array library with a powerful loop fusion framework. The main highlights compared to previous versions are: * DPH-style unboxed vectors (in Data.Vector.Unboxed) which use associated types to select the appropriate unboxed representation depending on the type of the elements. * A redesigned interface between mutable and immutable vectors. In particular, the popular unsafeFreeze primitive is now supported for all vector types. * Many new operations on both immutable and mutable vectors. * Significant performance improvements. The library comes with a fairly complete testsuite (mainly thanks to Max Bolingbroke) and is quite stable by now. Barring various disasters, I expect to release version 1.0 in the next 3 to 4 months. The release is accompanied by a new version of the NoSlow array benchmark suite. A few quite meaningless preliminary benchmarks are available at: http://unlines.wordpress.com/2010/02/15/vector-0-5-is-here-2 Both vector and NoSlow are on Hackage. Hackers can get the darcs repos from http://code.haskell.org/vector and http://code.haskell.org/NoSlow Enjoy! Roman
