New Relic has announced that its RPM Rails Performance Management tool successfully manages web applications running on the recently released Rails 2.2 version.

"Ruby on Rails is always evolving and has over the past five years gone through some fifty-plus public releases," said David Heinemeier Hansson, creator of Rails and member of the Rails Core Team. "Rails developers need the supporting ecosystem to keep up with that evolution. New Relic is proving that they're willing to do just that by being quick to ensure compatibility with Rails 2.2."

Ruby on Rails is an open source web application framework for the Ruby programming language. Rails was created by David Heinemeier Hansson and is supported by a core team of developer-committers. Rails is used by the web development community because it enables development of high-performing, functionally rich applications, often developed using an Agile Development methodology. Rails version 2.2 was released on November 21, 2008. The most notable features are an internationalization framework, thread safety, easy access to HTTP caching, compatibility with Ruby 1.9 and JRuby, and new documentation.
