Upgrading from Rails 2.1 to 2.2

I have a small project that I developed at work using Rails 2.1. After installing the latest version of Rails, 2.2.2, I had to do the following to get my project working again:

• Edit config/environment.rb and change the value of RAILS_GEM_VERSION to ‘2.2.2’.
• Edit config/environments/development.rb and comment out the config.action_view.cache_template_extensions line.
• Run rake rails:upgrade. This added a new file, script/dbconsole, and modified the following files:
  • config/boot.rb
  • public/javascripts/controls.js
  • public/javascripts/dragdrop.js
  • public/javascripts/effects.js
  • public/javascripts/prototype.js
