Yesterday, the first stable version of Ruby 2.0 series was released. The date for this major release was carefully chosen by the Ruby development team to be Ruby's birthday, now turning 20 years old! We wanted to join this celebration by doing what we do best. Our present: providing you with the the easiest way to test Ruby 2.0 :)
Bitnami Rubystack provides free, all-in-one installers for Windows, OS X and Linux, virtual machines and Amazon machine images that provide a self-contained Ruby environment. It includes the Ruby runtime (of course!), Rails and a bunch of other commonly used third-party libraries and servers such as Rails, RVM, Imagemagick, MySQL, etc. The packages will not interfere with your existing development environment and you can easily add/remove them at will. In fact, one of the preferred use cases for our stacks is to quickly test new versions of popular open source apps
Give it a try!
