Drupal is always changing

This book was started just as Drupal 8.0.0 was about to be released and was finished shortly before Drupal 8.1.0 was about to be released. In between were 8.0.1 through 8.0.5, a new release about every two weeks. With each release, a number of issues were resolved. Some of those issues affect how Views operates or the wording of some screen text or prompts. The evolution of Drupal and Views will continue long after this book is done. As a result, it is very likely that some screens and prompts described here might not match your copy of Drupal exactly. The differences are minor changes in wording to improve the understandability or clarify the meaning. Do not be alarmed if there are small differences between this book and Views when you use it. These differences will be mostly cosmetic, although it is possible that a new option might appear.
