No specific date has been set yet for the release of Rails 3.1. “Rails is still baking, but we can see the end,” Hansson said. The Rails blog also notes the release this week of Rails 3.0.7. “The main change in this release is to fix a performance regression in Active Record that was introduced in version 3.0,” according to the blog. Active Record offers a base for models in a Rails application as well as database independence.
