Now that the beta release of Ruby on Rails 3 is available, we wanted to make it easy for you to check out all of the improvements that have been made. We just released a new version of BitNami RubyStack that allows you to install a complete, ready-to-run Rails 3 environment in just a few clicks. If you choose to install the stack natively, you will be asked if you want to install the Rails 3 gems or not. If you opt out, you will have a stable release of Rails installed and completely configured.
As with all BitNami Stacks, RubyStack is completely self-contained and relocatable. This means that you can install the Rails 3 beta stack alongside your existing Rails installation without interfering with it, so you can work with older versions of Rails at the same time you are testing the latest release. A bundled uninstaller makes it easy to remove the complete Rails 3 beta environment when you no longer need it.
In addition to a native installer, BitNami RubyStack is also available as a virtual appliance and an Amazon Machine Image (AMI), so you can deploy it in a virtual environment or to the Amazon EC2 cloud.
