First Ruby on Rails App: use v3 (Beta) or 2.3?
ruby, ruby-on-rails, ruby-on-rails-3
Solution
I'd suggest sticking with the non-beta version (2.3). Chances are tutorials and/or webcasts you might use are for the older version. Go for version 3 only if it includes features you actually need that are not in 2.3.
Problem
Now that Rails 3.0 beta has been released, should I spend time building my first Rails application on 2.3 or does it make more sense to use the beta?
