Agile Web Development with Rails, by Dave Thomas (of Pragmatic Programmers) and David Heinemeier Hansson (the original creator of Rails) has been the framework’s bible since the publication of the first edition in mid-2005. With the rapid evolution of the framework, the book didn’t last long before a second edition was badly needed.

To meet the urgent need of the community and gain feedback at the same time, Pragmatic Programmers has been publishing “beta books” in PDF form. All of us who have downloaded multiple versions and awaited a nicely bound, proofread, and indexed copy can finally rest easy: the book went to the printer yesterday.

If you can’t wait a few more weeks, you can buy the PDF-plus-printed-book package and get the PDF right away, with the book to follow when it’s back from the printer.
