A pre-alpha version of IronRuby has been released. John Lam writes:
We've been working very hard over the past couple of months to get our first source code release ready. I'm happy to announce today the first drop of the IronRuby source code. IronRuby is licensed under very liberal terms as set out by the Microsoft Permissive License.
We're also happy to announce that we will be accepting source code contributions into the IronRuby libraries. Right now we have a lot of logistical work that we still need to do, but we fully intend on getting IronRuby onto Rubyforge by the end of August.
