This is the request to port any relevant documentation of the Fuse 7 Apache Camel Development Guide to Red Hat Build of Apache Camel 4 documentation.

Pretty much all four parts of that Fuse 7 documentation

• Part I. Implementing Enterprise Integration Patterns
• Part II. Routing Expression and Predicate Languages
• Part III. Advanced Camel Programming
• Part IV. The API Component Framework

... are still relevant for Camel 4.x but may need some updates as APIs might have changed.
