Online release notes:

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/> 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> 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> extension

 load_assembly "System.Core"
using_clr_extensions System::Linq
# ...
  where(lambda { |p| p.units_in_stock == 0 }).
  each { |x| puts x.product_name }

For more information see the LINQ 101 sampes ported to
