Congratulations to Wayne Kelley and the folks at QUT!
They just announced the release of version 0.9 of Ruby.NET! I have included the entire text of the announcement below.
This is the first open source community edition of Ruby.NET. In July of this year, the team at QUT decided to transfer complete control and ownership of the project to the Ruby and .NET open source communities and to strongly encourage others to directly contribute to and steer the project (staff at QUT remain, however, strongly committed and heavily involved in the project).
This new version includes substantial improvements, including improved Ruby/.NET interoperability, .NET subtyping, creation of .NET delegates using Ruby blocks and support for visual design of Windows Forms applications within Visual Studio. We’ve also fixed lots of bugs and are close to getting Ruby on Rails to run successfully.
We look forward to you feedback. A Google group has been set up for discussing the Ruby.NET compiler project. The email address is RubyDOTNET@googlegroups.com and you can join at http://groups.google.com/group/RubyDOTNET.
We are getting close to releasing our first "production quality" release, version 1.0. If you are interested in using Ruby.NET for "production purposes", please contact us as we'd be happy to work with you in creating some showcase examples of real world usage.
You can download it now from our new home page at http://rubydotnet.googlegroups.com/web/Home.htm.
