Detailed Description

Ruby 2.0.0 is upstream's new major release of Ruby. It caries new features such as:

  • Refinements
  • Keyword arguments
  • Enumerable#lazy
  • Module#prepend
  • #to_h: Convention for conversion to Hash
  •  %i: a literal for symbol array
  • regexp engine was changed to Onigmo
  • DTrace support
  • TracePoint

Yet, it is source level backward compatible with Ruby 1.9.3, so you will continue to work.

The updated Ruby also provides better integration with Fedora, especially JRuby. But not only JRuyb, it is also one step closer to be prepared for other interpreters, such as Rubinius. Providing of custom Ruby loader with working name "multiruby" [1] will allow to easily switch interpreters executing your script, provides fallback to whatever Ruby interpreter is available on you system, yet still keeps backward compatibility with all your Ruby scripts.
