title: Of the changes to Rails between 1.x and 2.x which ones have actually affected your work in Rails?
body: <p>I'm doing a course on Rails that focuses on version 1.1.6 so I'm trying to figure out which of the numerous changes between 1.x and 2.x are the most critical to be aware of for practical use. At the moment I don't need to know all the little nitty gritty changes - just the big ones.</p>
