I have a question that I feel should be really easy to figure out, but
I’m very new to Rails and Googling hasn’t really produced anything of
consequence.
I started an app using the first release candidate of Rails 3. Now
that the final version is out I’d like to change the app over. Is it
as simple as changing the gem specification in the Gemfile? I feel
like there should be more to it, but have no idea.
