As Matthew MacDonald points out in the book, the main changes to the new version have been streamlining and modernizing Access by kicking out some of its oldest and creakiest features. The only main addition has been support for web apps that essentially are web based apps running on the SQL Server data engine with a SharePoint 2013 server to host them. In view of what’s been taken away – Access data projects, the upsizing wizard, pivot tables and pivot charts, and data collection through email – many Access programmers would be better off sticking with Access 2010. However, if you are forced to upgrade, this book is a reasonable option for learning the basics of what’s on offer. If you have an earlier version of the book, you’re probably fine sticking with it unless you’re unsure on the web based apps, which are covered in the new edition.
