The Ruby on Rails 3.0.3 web development framework was released this week, restoring performance lost when the open source framework was upgraded to Rails 3.x.

The upgrade bolsters the Active Record technology in Rails, which provides the basis for models in Rails applications along with such capabilities as data validation and database independence.

"How about some free speed? Well, here you go. Rails 3.0.3 includes a much faster version of Active Record that reclaims the performance lost when we went from Rails 2.3.x to 3.x and then some," Rails founder David Heinemeier Hansson.

Version 3.0.3 also features minor fixes, Hansson said. "So everything just works better and faster. What more can you ask for? Oh, that it's a drop-in replacement for Rails 3.0, there are no API changes. You got it."

Rails 3.0 was released in late August, offering boosted performance capabilities as a result of a merger with the Merb framework. Cross-site scripting protection by default also was included.
