In preparation of a Spring Boot service release on the horizon, I am pleased to announce the fourth service release of the Spring Data release train Gosling. As usual, service releases contain bugfixes — 45 in total this time —, so that an upgrade is highly recommended.

On behalf of the Spring Integration team I’m happy to announce the First Milestone of the Spring Integration 4.3 release.

4.3 is planned to be 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.

We plan on finalizing 4.3 over the next few months before switching our attention full-time to 5.0 so, if there is some must have feature you need before next year…

It's my pleasure to announce that the first milestone of Spring REST Docs 1.1 has been released. 1.1.0.M1 is available from https://repo.spring.io/milestone/.

What's new?

REST Assured

As an alternative to the lightweight server-less documentation generation offered by Spring Framework's MockMvc, you can now use REST Assured to test and document your RESTful services. This opens up Spring REST Docs to all four corners of the JVM and beyond, allowing you to document anything that you can access via HTTP.

Markdown

Support has been added for generating Markdown snippets. On its own, Markdown isn't as capable as Asciidoctor, but can work very well when combined with existing documentation toolchains such as Slate…

Entering Reactive Streams Era

Reactor 2.0 development started by the end of 2014, around the same time as Reactive Streams. We were keen on joining the effort and early adopt a backpressure protocol to mitigate our main message-passing limitation: bounded capacity. We delivered in Reactor 2.0 the first attempt to make Reactive Streams implementations of RingBuffer-based schedulers and derived an increasingly popular reactive pattern: Reactive Extensions.

Meanwhile, Reactive Streams started getting traction and an entire ecosystem of libraries discussed this transition. The regular concern ? Implementing Reactive Streams semantics is all but an easy task. We observed an increasing need for a reactive foundation to solve message-passing and implement common streaming operators. We therefore created a dedicated project space for Reactor Core and started a focused effort with Spring Framework team…

On behalf of the Spring Data team I'm happy to announce the first milestone of the Hopper release train. The release ships 250 tickets fixed! The most important new features are:

• Upgrade to Querydsl 4.
• Integration of Spring Data Neo4j 4.1, Spring Data Couchbase 2.1 and Spring Data Solr 2 (on Solr 5).
• Support for Redis Cluster.
• Support for projections on repository query methods in JPA and MongoDB (see the example for details).
• Addition of Spring Data Envers to the release train (previously maintained separately).

Find a curated changelog in our release train wiki or skim through a full list of changes in JIRA. We're shooting for a release candidate early March and a GA release at the…

On behalf of the community, I'm pleased to announce the release of Spring Session 1.1.0.RC1. The release can be found in the Spring Milestone Repository (https://repo.spring.io/milestone/).

This release contains lots of fixes and new features. You can find details in the What's New in 1.1 The highlights of 1.1.0.RC1 have been included below:

• Support for GemFire Thanks to John Blum!
• Allow writing to Redis immediately (instead of lazily) using redisFlushMode

We look forward to your feedback and if all goes well plan to release 1.1.0.RELEASE in the next few weeks.

On behalf of the team, I am pleased to announce the release of Spring Cloud Stream 1.0.0.M4. The new release comes with a few major changes and enhancements, and it defines core abstractions and primitives that we believe to be essential for the development of distributed real-time data processing applications. To name some of them:

Default publish-subscribe semantics

The most important change in Spring Cloud Stream 1.0.0.M4 is the way in which applications interact with each other. We have opted for a default publish-subscribe model, in which each application that receives messages from a given destination will receive a copy of the message. This is a better fit for the processing model of stream applications, where intermediate topics act as data hubs for the various intersecting data streams, also making scenarios such as tapping easier and more efficient. This feature goes hand in hand with the next, which is consumer groups…

We’re pleased to announce a first milestone release of Spring Statemachine 1.1.0.M1.

We released 1.0.0.M1 April 2015 and 1.0.0.RELEASE October 2015. We've also done 2 maintenance releases for 1.0.x series and now it's time to look in a future with a 1.1.x serie. 1.0.x enters into a maintenance mode while main development will focus on 1.1.x. This doesn't mean that we'll stop with 1.0.x, maintenance fixes for it will be done until we're succesfully transitioned beyond 1.1.x release. It is important in Spring projects to not drop maintenance until users are ready to move on into next minor/major…

Spring IO Platform 2.0.2.RELEASE is now available from both repo.spring.io and Maven Central.

This maintenance release upgrades the versions of a number of the projects in the Platform to pick up their latest maintenance releases:

• Spring AMQP 1.5.3.RELEASE
• Spring Boot 1.3.2.RELEASE
• Spring Integration Java DSL 1.1.2.RELEASE

The versions of several third-party dependencies have also been updated.
