Welcome to another installment of This Week in Spring!

• The BIG news: Spring Cloud Brixton is now available! Get the bits from the Spring Initializr. If you'll permit a little back-patting, I submit that you might get a good feel for what concerns a technology like Spring Cloud addresses by reading this article I wrote and you'll learn how Spring Boot and Spring Cloud are used in this video. That said, grab the bits and go!
• Spring Cloud Stream 1.0.0 is here, at long last! Spring Cloud stream makes it simple to build collaborating messaging-based microservices.
• Spring Boot co-lead Phil Webb just announced that Spring Boot 1.4.0.M3 is now available, just in time…

I am pleased to announce the availability of Spring Integration 4.3.0.RC1 - the first (and final) release candidate; it is available from the spring milestone repo The GA release should follow shortly after the GA release of Spring Framework 4.3.

4.2.6.RELEASE is also available in the spring release repo as well as maven central. This release includes a few important bug fixes and all users are encouraged to upgrade to it.

4.3 is only a minor release with a few new features and improvements over 4.2 and will close out the 4.x line. Meanwhile we are looking forward to embrace the Reactive Foundation for the JVM in Spring Integration 5.0. We have yet to determine exactly what that means, so stay tuned! In addition, 5.0 (2017) will include the (currently separate) Spring Integration Java DSL…

On behalf of the team, I am pleased to announce that the Spring Cloud Brixton Release Train has reached General Availability. The release is available today and can be found in our Spring Release repository and Maven Central.

We would like to thank many community contributors and testers for their help. There have been many pull requests, issues and conversations that have made Spring Cloud Brixton better.

Highlights

Some of the highlights of the Brixton Release Train are:

• Spring Boot 1.3.x and Spring Framework 4.2.x support
• Hashicorp Consul support for service registration/discovery & configuration via Spring Cloud Consul
• Apache Zookeeper support for service registration/discovery, configuration via Spring Cloud Zookeeper and leader election in Spring Cloud Cluster
• Distributed tracing through the Spring Cloud Sleuth abstraction with two out of the box implementations: one supporting logging (ideal for log collectors and multiplexers like Logstash and Loggregator) and one supporting Twitter's Zipkin
• Netflix Atlas Telemetry System, the next generation Spectator Metrics library…

Shortly after 1.3.4, we've just released Spring Boot 1.3.5 as we've identified a rather nasty regression with the Spring Integration auto-configuration. The bits are available from repo.spring.io and Maven Central, as usual.

On behalf of the team, I am pleased to announce the general availability of Spring Cloud Stream 1.0.0.RELEASE. The artifacts can be found in Spring Repository as well as Maven Central.

The goal of Spring Cloud Stream is to be a lightweight framework for developing event-driven microservices, building on the ease of development and deployment of Spring Boot, and the component model and integration capabilities of Spring Integration. As part of the Spring Cloud family of projects, it has a specific focus on cloud-native architectures.
