• Full Java 8 and Spring Framework 5.0 support;

• New spring-rabbit-junit artifact with some useful testing utilities including BrokerRunning JUnit @Rule;

• The amqp-client library of version 5.0;

• A DirectMessageListenerContainer to allow to consume messages directly on the client thread instead of queue-based logic in the SimpleMessageListenerContainer;

• A ConnectionNameStrategy option for the ConnectionFactory to name target Broker connections for possible diagnostics;

• new RabbitOperations.invoke() for batch of template operation on the dedicated, thread-bound channel;

• Encoder support for the Logback AmqpAppender;

21 JIRAs (and some GitHub issues) made into this release, including bug fixes and a number of new features. Some highlights of features in the M7, since the previously announced Milestone 6:

• Reactive WebFlux Channel Adapters has been extracted to the separate spring-integration-webflux module to distinguish Servlet-based MVC configuration from the Reactive foundation.

• The EmbeddedJsonHeadersMessageMapper is introduced to allow embedding message headers together with the payload into packages for target protocols which doesn’t support headers natively, for example TCP/IP, MQTT, AWS Kinesis and Apache Kafka before version 0.11.x.

Functionally, the 1.3.x line provides a subset of the 2.0 line (which requires Spring Framework 5.0 and Java 8), but provides support for Java 7 projects and Spring Framework 4.3.x.

It is primarily intended to provide early access to 0.11.0.0 Apache Kafka client…
