I've been learning Rails from your tutorial (just finished Chapter 11), but realised a few days ago that I've been using the 3.0 version. It'd be great to see an appendix on "Transitioning to 3.2 for first edition readers" (probably like the one you've got for 3.0 -> 3.1, but I haven't got to reading that yet.) And while I'm here, there is a bug in the 3.0 edition in section 11.3.4, listing 11.39. The link_to "delete" needs to reference 'feed_item', not 'micropost'. That took me a good half an hour to sort out - mainly because I assumed it was my fault, not yours! :-) Thanks for all your efforts here; this is a fantastic resource.

Oops, you're right. That's actually a new bug, and has now been fixed. As far as the transition goes, that's a great candidate for a blog post, but it's not as good a fit for a book. Plus, experience shows that starting from scratch often takes less time in the end.

  Fair enough. My current plan when I've finished is to rewrite my collaborative blogging platform in Ruby (was Google App Engine + Python). It's got enough similarities to a twitter clone that I can base a lot of the infrastructure on railstutorial, but enough differences that I will definitely start from scratch rather than trying to modify the codebase. I guess I should move to rails 3.2 at the same time, and whizz through your new version in parallel. Thanks for fixing the bug.
