Upgrading to rails 2.3.2
Before today I was running on rails 2.2.2, but now I need the new rails engine feature so I had to upgrade.Ok, I would have to anyway 
It wasn’t that hard.
sudo gem install rails
and renaming application.rb to application_controller.rb did everything required for my development environment. I use hoptoad for error aggregation in production, so I had to update the gem for production.
That’s all!
