Book Out of Print, API Decommissioning

This book is now over 6 years old and web technologies have moved on. As a result, we are sunsetting support for this book including the tracking APIs that were used for the tracker and coffee run applications. Ottergram and Chattrbox should still work, though again the code is outdated.

In early 2023, we will be releasing a new book specifically about React development. (The new book will not be dependent on any outside APIs.)
