If you are Maven user you may be interested in the new "bill of materials" POM that we have published with this release. You can import the spring-framework-bom project in your dependency management section to ensure that you get consistent Spring Framework dependencies.

We are extremely pleased to announce that Spring Integration 3.0.0.RC1 is now available in the Spring Milestone Repo

This release uses Spring Framework 3.2.5 by default but is also compatible with Spring 3.1.x and 4.0.x.

The release notes, showing changes since milestone 3, are available here.

##First, a Note About Spring Framework 4 Support

Spring Framework 4.0 has a new spring-messaging module that contains a number of key abstractions from Spring Integration.

Spring Integration 3, while being compatible with Spring Framework 4, does not depend on it, and does not use these classes, so that it can also be used with Spring Framework 3.2 and 3.1.

I'm happy to announce that Reactor, a powerful foundational library for building reactive, fast data applications on the JVM has reached GA!

What is Reactor and why should I care?

Reactor provides the necessary abstractions to build high-throughput, low-latency--what we now call "fast data"--applications that absolutely must work with thousands, tens of thousands, or even millions of concurrent requests per second.

You should care about Reactor because modern applications with non-human consumers--like mobile phones and the apps that run on them--generate more data than traditional thread-per…

Spring Boot 0.5.0.M6 has been released and is now available in the Spring repo. Instructions for installing and using are on the project website or in github. There are loads of updates in this release, including:
