13 March 2015 P1.1

We discovered some images had been omitted from the epub and mobi versions. We’ve fixed that now, so if you’re reading this book on iBooks, a Kindle, or any ePub reader you’ll probably want to refresh.

There are no content changes—just the new images.

If you’re reading the PDF or paper book, you already have these images, so there’s no need to do anything.
