Rails Tutorial book (online vs. PDF)

Regarding the recent changes to the Rails Tutorial book due to the release of Rails 3.0.6, one reader asked if the changes applied only to the online book or if the PDF book has been updated as well. This is a reasonable question; the answer is that both versions of the book are produced from the same source file, so they are always in sync by construction. If you purchased the Ruby on Rails Tutorial PDF or the PDF/screencast bundle, simply search through your mail program for "Ruby on Rails Tutorial purchase" and visit the original PDF download link to get the latest version of the book.
