BitNami has just announced new BitNami RubyStack and Redmine stacks versions with Ruby 1.9 and Passenger 4 beta that significantly improves the performance in production environments. The default configuration uses Apache running with the Passenger module. However, if you prefer to use Nginx with Passenger, it ships Nginx server and Passenger extension already compiled and ready-to-use.

BitNami provides all-in-one free native installers for Windows, OS X and Linux, virtual machines and Amazon Cloud Images that simplify the Ruby applications installation and hosting.
