Ruby and .NET developers, The IronRuby team is pleased to announce IronRuby 1.0! Download IronRuby 1.0 now: [http://ironruby.net/download](http://ironruby.net/download) Direct download links (Windows installers and ZIP files for both .NET 2.0 SP1 and .NET 4.0): [http://ironruby.codeplex.com/releases/view/25901](http://ironruby.codeplex.com/releases/view/25901) IronRuby 1.0 is the first stable version of IronRuby, targeting Ruby 1.8.6 compatibility. For a high-level compatibility report solely based on RubySpec, see [http://ironruby.info](http://ironruby.info). For a detailed change-log since 0.3, see the change-log page: [http://rubyforge.org/frs/shownotes.php?release\_id=43292](http://rubyforge.org/frs/shownotes.php?release_id=43292). IronRuby now comes in two flavors - one that runs on top of .NET 4.0, and one that runs on any earlier framework starting with .NET 2.0 SP1. The .NET 4.0 flavor features faster startup time, compatibility with C#'s dynamic keyword, and access to the new features in .NET 4.0. So, the .NET 4.0 flavor is the preferred download now, as the Microsoft .NET Framework 4.0 is publically available as of today. For Mono compatibility, use the zip file release for 2.0 SP1. Download .NET 4.0: [http://www.microsoft.com/downloads/details.aspx?FamilyID=9cfb2d51-5ff4-4491-b0e5-b386f32c0992](http://www.microsoft.com/downloads/details.aspx?FamilyID=9cfb2d51-5ff4-4491-b0e5-b386f32c0992) Since IronRuby’s first public release there have been 455 reported bugs fixed, 98 community members reporting bugs, 100+ code contributions by 15 community members, and 11 core-team members. Thank you to everyone who made IronRuby 1.0 possible: IronRuby Core Team Alumni: Curt H., Dave Remy, Haibo Luo, John L., John M., Oleg Tkachenko, and Srivatsn Narayanan. Source code contributors: Daniele A., Eric N., Ivan Porto C., Jayme Edwards, Jb Evain, Jirapong Nanta, Kevin R., Michael L., Peter Bacon Darwin, Ryan R., Seo S., Shay F., Timothy Chen, Unnikrishnan N., and Wayne K… Bug Reporters: Aghoda, akaranta, Alex C., Alexandro Rocha, Andrius Bentkus, Antonio Cangiano, Antti Karanta, aslakhellesoy, atownley, Bela Babik, Ben H., Bex\_3000, Brad W., Brian Blackwell, brunomlopes, Charles L., chrismaduro, Coder42, crèmes, Dan Fitch, Daniele A., DavidSchmitt, daytrip00, DotNetNerd, eoinomeara, Eric N., Florian Kruesch, giggio, glennen, Greg Houston, harald42, hedge\_hog, hoornet, hotgazpacho, i\_iob, imasho, Ivan Porto C., Jirapong Nanta, john5exonets, Joxter Mumurik, just3ws, Justin B., JustinCle, jwthompson2, K E, kaiwren, KAZUu, Kevin R., kralor, lukesmith, m4dc4p, maslov, mayuki, meinrad recheis, michaelerasmus, MiddleTommy, motobuzz, Narko, Nick , chrock, niclasnilsson, nikosd, Nobody, nolith, Orion E., ourben, Peter Bacon D., PlasticLIzard, pwistrand, raubarede, Ray Vernagus, rbandrews, rbrother, rifraf, riles01, Robert Brotherus, rohancragg, romanvbabenko, ruzplex, Seo S., SergeyMirvoda, shannoncornish, Shay F., Stefan D., Steve Eichert, stkenned8, Thibaut Barrère, TimothyB, timross, Timothy Chen, turp, undees, vaderpi, vertiginous, vvnurmi, Wayne K., xerxesb, xport, and Zyl Wolf. I think I speak for everyone when I extend a very special thanks to John Lam, for without his pursuit of an integration between Ruby and the CLR, IronRuby would surely never gotten a chance to exist. As always, if you find any bugs or have a feature request, please open an issue on CodePlex: [http://ironruby.codeplex.com/WorkItem/Create.aspx](http://ironruby.codeplex.com/WorkItem/Create.aspx). We hope you enjoy writing Ruby code for the .NET framework, and thank you for your continued support! Sincerely, The IronRuby Core Team Shri B., Jim D., Tomas M., and Jimmy S. ---
