On behalf of the team I am pleased to announce the release of Spring Cloud Data Flow 1.0 RC1.

Several exciting new features have been added in this release which carry over to the other Data Flow Server implementations that were also released today.

Data Flow Local Server

Data Flow for Cloud Foundry

Data Flow for Apache YARN

Data Flow for Kubernetes

Data Flow for Apache Mesos

Follow the links above for details on features unique to each individual runtime platform. The highlights of the release are:

• Spring Flo is now an open source project and has been integrated into the Spring Cloud Data Flow dashboard allowing you to visually design data pipelines in your browser.

We are pleased to announce the release of Spring Cloud Task 1.0.0.RC1. This is the first release candidate of the Spring Cloud Task project!

What's New?

This release really represents the polishing of the functionality that existed within 1.0.0.M2:

• The TaskRepository
• Task listeners
• Task integration with Spring Batch
• Task integration with Spring Cloud Stream

There are a few minor breaking changes (renaming of a few methods) but those are all to get things right for our 1.0.0.GA. This release will serve as the baseline version of Spring Cloud Data Flow's 1.0.0.RC1 as well.

What's Next?

On behalf of the Spring Data team I’d like to announce the availability of the second service release of the Spring Data Hopper release train. The release ships 103 issues fixed. We fixed a couple of bugs in the area of repository projections, especially for JPA users and introduce Hibernate 5.2 compatibility with this release (also already back-ported to the Gosling release train for inclusion in the upcoming service release). Hopper SR2 is a recommended upgrade for all Hopper users and also users of previous release trains.

Dear Spring community,

I’m pleased to announce that Spring Integration Framework 4.3 GA is now available from repo.spring.io, as well as Maven Central! Also the maintainance 4.2.8 version has been released, too. Together with an internal 4.2.7 release it includes some important bug fixes.

In addition to the feature themes mentioned in 4.3 RC1 announcement, the GA release includes several major changes:

• Upgrade to Spring Framework 4.3 GA, Spring AMQP 1.6 GA, Spring Security 4.1 GA;

• The FtpRemoteFileTemplate now provides ExistsMode option to control how an exists() operation should work;

• The FileSplitter lets represent FileMarker object as a JSON string (markersJson option) to avoid an additional spring-integration-file dependency on the consumer applications in distributed environments;

• A new JdbcLockRegistry feature has been introduced. Special thanks to Dave Syer!

• The Integration Graph has been improved with generic gateway nodes and LinkNode now has a type (input, output, error, discard, route) property for better visualization experience;

Welcome to another installment of This Week in Spring! This week I'm in London and Amsterdam (for the epic GOTO Amsterdam conference as well as the JDriven meetup and the Dutch Spring User Group). We've got a lot to cover, as usual, so let's get to it!

• Spring framework 4.3, packed with all sorts of niceties, is now available. This release provides all sorts of cool updates to various libraries (Hibernate ORM, Jackson, Netty, Undertow, Tomcat) and supports two features I'm quite excited about: auto-injection in constructors of Spring managed components whose parameters are unambiguously resolved by other types in the application context and the ability to inject types into a @Configuration-class's constructor.
• Marius Bogoevici just announced a critical update to Spring Cloud Stream, 1.0.2.RELEASE, is now available for immediate use
• the good Dr. David Syer posted the second in a series of posts looking at the reactive programming landscape…

On behalf of the team, I am pleased to announce that Service Release 1 of the Spring Cloud Brixton Release Train is available today. The release can be found in our Spring Release repository and Maven Central.

This is primarily a bug fix release with a few small features. Of particular note is a change that allows Brixton Eureka Servers to work with Angel Eureka clients.

The following modules were updated as part of Brixton.SR1:

• Spring Cloud Commons 1.1.1.RELEASE
• Spring Cloud Config 1.1.1.RELEASE
• Spring Cloud Consul 1.0.1.RELEASE
• Spring Cloud Netflix 1.1.1.RELEASE & 1.1.2.RELEASE
• Spring Cloud Sleuth 1.0.1.RELEASE
• Spring Cloud Stream 1.0.2.RELEASE
• Spring Cloud Zookeeper 1.0.1.RELEASE

In this article we continue the series on Reactive Programming, and we concentrate on explaining some concepts through actual code samples. The end result should be that you understand a bit better what makes Reactive different, and what makes it functional. The examples here are quite abstract, but they give you a way to think about the APIs and the programming style, and start to get a feel for how it is different. We will see the elements of Reactive, and learn how to control the flow of data, and process in background threads if necessary.

Setting Up a Project

We will use the Reactor libraries to illustrate the points we need to make. The code could just as easily be written with other tools. If you want to play with the code and see it working without having to copy-paste anything, there are working samples with tests in Github…

Dear Spring community,

I'm pleased to announce that Spring Framework 4.3 GA (a.k.a. 4.3.0.RELEASE) is now available from repo.spring.io as well as Maven Central!

In addition to the feature themes mentioned in my 4.3 RC1 announcement, the GA release covers compatibility with several recent third-party releases, in particular: Hibernate ORM 5.2, Jackson 2.8, Netty 4.1, Undertow 1.4, and Tomcat 8.5.2 / 9.0 M6. Also, please note that our Hibernate 3.x support is finally deprecated (even Hibernate 4.x is not actively supported by Red Hat anymore) and that Spring 4.3's Jackson support requires…

Shortly after the 1.0.1.RELEASE announcement last week we’ve identified a critical and very specific issue concerning multi-binder configurations in cloud environments. As a result, we have decided to follow up with a 1.0.2.RELEASE to handle that and ensure that the fix is available in the upcoming Brixton.SR1 release. The artifacts can be found in Spring Repository as well as Maven Central.

I will be talking about Spring Cloud Stream at Spring One Platform, which will be taking place in Las Vegas between August 1-4 this year. There are many other great talks so check the agenda and get your ticket if you haven’t done so…
