intertwingly

Agile Web Development with Rails, Third Edition beta 4 is now available.  All chapters, with the exception of Web Services which is likely to be replaced by a chapter on ActiveResource, have been updated to work with Rails 2.1.

Frankly, I was astounded (one might even say blindsided) by the sheer volume of changes that occurred between Rails 1.2.6 and 2.1.  To be fair, most changes won’t affect deployed applications, but in terms of a book that starts with scaffolding and then documents how you introduce new function based on that scaffolding, most of the broad strokes remain the same, but many, many, many details have changed.

But that’s now behind me.  I’m now looking for suggestions on what new features are in edge Rails today that deserve specific focus and expanded coverage in the next beta.
