Fellow Haskellers, I am pleased to announce the final, stable release of Edison 1.2. Edison is a library of efficient, purely-functional data structures for Haskell. Many thanks to all of you who helped with your comments and suggestions during the release candidate phase! Edison 1.2 represents the first major release of Edison in several years and my first release as maintainer. The following list highlights major changes since the 1.1 release: * Typeclasses updated to use functional dependencies * Several new implementations * Modules renamed to use the hierarchical module extension * Documentation haddockized * Source moved to a darcs repository * Build system cabalized * Unit tests integrated into a single driver program which exercises all the concrete implementations shipped with Edison The project homepage is located at: http://www.eecs.tufts.edu/~rdocki01/edison.html API documentation is avaliable at: http://www.eecs.tufts.edu/~rdocki01/docs/edison/index.html And the main source distribution may be downloaded from: http://www.eecs.tufts.edu/~rdocki01/projects/edison-1.2-source.tar.gz Distribution package maintainers may be interested in the following split-source distributions: http://www.eecs.tufts.edu/~rdocki01/projects/edison-core-1.2-source.tar.gz http://www.eecs.tufts.edu/~rdocki01/projects/edison-api-1.2-source.tar.gz I would also like to take this opportunity to invite you to participate in making Edison better. The following list represents the things that Edison currently most needs. If you are interested in helping, please let me know! * Additional implementations. Edison currently has a fairly large collection of sequence implementations, but few collection or associated collection implementations. * Benchmarking suite. Edison needs a comprehensive benchmarking suite to allow objective comparison of different data structure implementations on various workloads. (perhaps the Auburn project could be revived?) * Documentation. The API is extensively documented, but the individual implementations are rather sparsly documented. Also, only sequences currently have time complexity data. * Users! Your experiences help me know how to improve Edison. If you decide to use or experiment with Edison, consider droping me an email to let me know what you like and don't like about Edison. After all, the squeaky wheel gets the grease! Enjoy!
