NOTE This screencast covers an unreleased
version of Rails 3 run from the source. Rails 3 Release
Candidate 1 has been
released
and we’ll update this screencast when the final version is available.

For several months people have wondered, “Where can I download a
video that features a developer stumbling through an upgrade of a
Rails 2 app to Rails 3?”

I’m proud to say that an answer is now available!

In only 25 minutes, I convert my news screenshot
site
from Rails 2.x to Rails 3
(prerelease, from source).

It features the newest bundler (0.9.0.pre), Jeremy McAnally’s
rails-upgrade script, new routes, Arel-based ActiveRecord
queries, and more.

Stay tuned for the explosions at the end!
