Answer / Ranjeet Kumar Yadav
Ruby 2.0 (also known as MRI 2.0) introduced several improvements over Ruby 1.9, including better garbage collection, a new YARV virtual machine that runs code faster and more efficiently, support for blocks with arguments, the ability to use the `a=b if b` syntax, and additional Unicode support.
