I’m pleased to announce the first (and the last) release candidate for Spring Integration 5.3.

This release ships several bug fixes, a bunch of new features and improvements and will be picked up by Spring Boot 2.3 RC1.

It can be downloaded from our milestone repository:

compile 'org.springframework.integration:spring-integration-core:5.3.0.RC1'

The most important new features are:

  • The MongoDbChangeStreamMessageProducer - a reactive MessageProducerSupport implementation for the Spring Data ReactiveMongoOperations.changeStream(String, ChangeStreamOptions, Class) API. This component produces a Flux of messages with a body of ChangeStreamEvent as the payload by default and some change stream related headers (see MongoHeaders).

  • The ReactiveMessageSourceProducer - a reactive implementation of the MessageProducerSupport to wrap a provided MessageSource into a Flux for on demand receive() calls.

  • The ReceiveMessageAdvice - a former AbstractMessageSourceAdvice is graduated now to more common advice approach which can be used also for the PollableChannel.receive() proxying.

  • The TcpOutboundGateway now can work in an async mode - you’ll get an actual reply from the returned Future.

  • We also have applied a GitHub default community health. Check this out when you try to raise a new issue https://github.com/spring-projects/spring-integration/issues/new/choose!

See What’s New? in the Reference Manual for more information. Also see a blog post for the previous Milestone 3.

We’re looking forward to your feedback for upcoming GA in May!

In addition to this 5.3 RC1 we also have released maintenance versions - 5.2.6 & 5.1.10 with some bug fixes and upgrades. Based on Spring Integration 5.3 RC1 and Spring for Apache Kafka 2.5 RC1 a spring-integration-kafka-3.3.0.RC1 was also released to pick up improvements and new feature from its "parents".
