PGAE 2015 is officially released!

The new Programming Google App Engine books are out! You can now order the print and ebook editions, including PDF, ePub, and Mobi from O'Reilly, as well as the Kindle edition from If you purchased the Early Release, you should now have the final ebook in your library on, and print pre-orders are on their way.

I'm extremely pleased with how these turned out. The new language-specific versions are gorgeous and easy to use, and I'm excited to have new material on important App Engine topics. Thanks to the efforts of many people, these new books have had more technical and editorial review than ever before. Of course, any remaining errors are my own, and I'll track errata on the About page as well as update the text. (Fixes get pushed to the ebooks and the print pipeline automatically, because O'Reilly is amazing.)

Spread the word, post reviews, and send me feedback. Thank you for all of your support!
