This chapter provides an overview of the new features and improvements that have been introduced with Spring Integration 4.0. If you are interested in more details, please see the Issue Tracker tickets that were resolved as part of the 4.0 development process.
Core messaging abstractions (Message,
MessageChannel etc) have moved to the Spring
Framework spring-messaging module. Users who reference these
classes directly in their code will need to make changes as described in
the first section of the
Migration Guide.
