The Live Edition of Learning Rails starts with an update of the book from Rails 2.1.1 to Rails 2.3.5. Code that changed over the past year or so has been cleaned up, as have errata that shouldn't have been there in the first place. Easy approaches to installing Rails that proved to be dead ends have been removed, while new material on jQuery has been added. The text has also been improved to make fewer assumptions that readers have gone through it in sequence, with reminders added about steps whose omission can cause strange problems.The forward-looking sections of the book include more recent information about the upcoming Rails 3, and future updates will explore this in greater depth as Rails 3.0 emerges.

More on Live Editions

O'Reilly Live Edition books give you access to updates to topics in between editions of a book. A Live Edition is an electronic version of the book that is updated when there is a significant change to the software or technology the book covers, keeping you on top of .X releases or major fixes.

Live Editions are updated frequently by the author as new information becomes available. When you purchase a Live Edition you have ongoing access to the electronic living version, which you can download at any point. You'll receive notifications when significant updates have been made so that you can refresh your download. And if you buy the Live Edition, you'll get electronic updates through the next full edition of the book. For Learning Rails, that means you'll get all updates for version 3.x of Rails.

Once the technology is considered stable in that issue, the book will undergo our normal process to be published as a next edition.
