- The IronRuby team is pleased to announce the release of IronRuby 1.1! Download IronRuby 1.1 now: [http://ironruby.net/download](http://ironruby.net/download) Direct download links: [http://ironruby.codeplex.com/releases/view/43540](http://ironruby.codeplex.com/releases/view/43540) Online release notes: [http://ironruby.codeplex.com/releases/view/43540#ReleaseNotes](http://ironruby.codeplex.com/releases/view/43540#ReleaseNotes) IronRuby 1.1\* is the first release after IronRuby 1.0, the first stable version of the Ruby 1.8.6 [http://ruby-lang.org/](http://ruby-lang.org/) compiler for the .NET framework. IronRuby 1.1 is _NOT_ fully backwards compatible with IronRuby 1.0; most notably that IronRuby 1.1 no longer supports .NET 2.0 SP1. .NET 3.5 is the minimum requirement for IronRuby 1.1, though using .NET 4.0 is strongly advised. Also, though this release is primarily bug-fixes for 1.0, consider any new features “Alpha” quality. This release adds support for .NET extension methods[http://msdn.microsoft.com/en-us/library/bb383977.aspx](http://msdn.microsoft.com/en-us/library/bb383977.aspx) in IronRuby. This works by calling the _using\_clr\_extensions_ method, which activates all extension methods defined on classes defined in a given namespace, regardless of the assembly they are defined in; assemblies loaded in the future that define extension methods in the activated namespace will automatically appear on the correct types. Here’s a simple example of using LINQ [http://msdn.microsoft.com/en-us/netframework/aa904594.aspx](http://msdn.microsoft.com/en-us/netframework/aa904594.aspx) extension methods: load\_assembly “System.Core” using\_clr\_extensions System::Linq # … products. where(lambda { |p| p.units\_in\_stock == 0 }). each { |x| puts x.product\_name } For more information see the LINQ 101 sampes ported to IronRuby[http://github.com/ironruby/ironruby/blob/master/Languages/Ruby/Samples/Linq/101samples.rb](http://github.com/ironruby/ironruby/blob/master/Languages/Ruby/Samples/Linq/101samples.rb) IronRuby 1.1 is now licensed under the Apache License (Version 2)[http://ironruby.codeplex.com/license](http://ironruby.codeplex.com/license), rather than the Microsoft Public License. This decision is based upon continual feedback and questions from the community, as well as for consistency between IronPython [http://ironpython.codeplex.com/](http://ironpython.codeplex.com/) and the Dynamic Language Runtime [http://dlr.codeplex.com/](http://dlr.codeplex.com/), which are now also licensed under the Apache License.
