Release Notes

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 For a detailed change-list since 0.3, see the release notes and changelog page.

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.

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.

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.

We hope you enjoy writing Ruby code for the .NET framework, and thank you for your continued support!

Reviews for this release

Excellent work! I especially love the Linq extensions. Did the etc lib make the cut?

It is just awesome. Ruby is really a serious development language. It already saved me tens of hours of development time.

Absolutely fantastic work, great achievement, and opens up a whole new world of techniques to .NET developers. Looking forward to 1.9.x compatibility.
