yes! If you go into your account on oreilly.com (assuming you purchased it from us) and go into "your products", there should be an "upgrade to the newest ebook edition" button. Clicking on that should take you to the cart and auto fill in the discount code for the upgrade (it's 50% off the newest edition).
If that doesn't work for you or if you have questions, drop me a line at email@example.com or give me a ring and I'll help sort it out for you.
