Good news! IronRuby and IronPython have just been released with new and shiny versions!

IronRuby 0.5

• Download IronRuby 0.5
• Adaptive compilation – performance boost!
• Removes ClrString. CLR strings are referred to as System::String
• Removes IronRuby library. "require 'IronRuby'" is no longer needed; IronRuby module is now a built-in module.
• Integer/Float operations for all CLR primitive numeric types
• System::Char and System::String methods so that they behave like an immutable UTF-8 encoded string
• Improves handling of BOM in 1.8 mode
• Debugger visualizer for RubyObject so that VS will display the result of to_s in the Watch window.
• Adds support for .NET operators (op_* special methods)
• Implements bitwise operators on flag enums
• Precompilation of simple Ruby method invocations
• Improves performance for file IO#read method. Previously we were 10x slower than MRI, now we are approx. 1.5-times faster.
• Tons of fixes to File, String, Array, and other built-in types to drive up RubySpec and Ruby application test-suite pass-rates. One bug fix is mine!
