Great stuff. The Rails Tutorial was my top resource when learning Rails and I still use it as a reference (along with RailsSpace and Railscasts). I'm using Rails 4 on a few projects, so if I can lend any feedback on the future release let me know.

Please do send feedback! Any significant structural changes will have to wait until the next full edition (slated for production later this year), but bug and typo reports are hugely appreciated. I typically process such reports as an email queue, so send them to [e-mail].
