In 2018 MuleSoft released Mule 4, the latest and most advanced runtime version for Anypoint Platform. Mule 4 introduces many changes and new features in order to enhance application development velocity with up to 50% fewer steps and concepts to learn, including: a simplified language for connectivity, clear access to data, automatic tuning, and smoother upgrade processes.

The idea behind the new book is to help the reader understand the changes and concepts introduced in Mule 4 and get them enabled on Anypoint Platform by helping them solve issues they come across.

After reading this book the reader should have gotten a strong overview of the MuleSoft Anypoint Platform and Mule 4, using practical and easy-to-follow examples. The authoring team comes from an organisation which has been awarded multiple times as partner of the year by MuleSoft and have been testing and working with Mule 4 since the beta release.
