The newly released chapters are substantial, and should be enough to keep readers busy for a while. I hope to release drafts of the final four chapters some time in the next week or so.
(Note to the curious: No, I can't write chapters this fast. It takes me two weeks to write a chapter from scratch, a few days for a major editing pass, and half a day to do the final edit. All the draft chapters had been through at least a major editing pass before the [main announcement](http://news.railstutorial.org/rails_tutorial_3rd_edition/) last week.)
