Thanks for the awesome feedback guys! If you find any glitches in the book, please put them on http://doc.silverstripe.org/doku.php?id=silverstripe-book-errata

There's no plan for a revised edition ... I'll ask the publisher (Wiley) how we go about the licensing of code examples. I'd be happy to put them on github and have you fork off a 2.4 revised version of it. With "code examples" I mean the downloads provided at http://au.wiley.com/WileyCDA/WileyTitle/productCd-0470681837,descCd-DOWNLOAD.html, so just the finished code for most chapters. We most likely won't be able to put the actual chapters around building the code online. Would that work for you?

Hello Raithlin, I've got word back from the publisher, they're OK with releasing the code under BSD. I've put it up on my github account: http://github.com/chillu/silverstripe-book. Hope you'll find it useful Keep in mind: This code was tested against 2.3.0 beta.
