Welcome to another installment of This Week in Spring! This last week's been nuts! So much good stuff on offer. Spring Framework 5.0 is now available! And with Spring Framework 5.0 comes a deluge of releases, all of which you'll see in this post. Also, this week I - and others from the Pivotal and Spring teams - are at JavaOne and I hope you'll come find us and say hi at our booth or the various talks.

• Last week I looked at using Spring Framework 5's support for building reactive websocket-based applications.
• Spring AMQP and Spring Integration lead Gary Russell has just announced Spring AMQP 2.0.RC2.
• At long last, Spring Framework 5.0.GA is here! The new release integrates with Project Reactor, includes a reactive web runtime, Kotlin extensions, and baselines on Java EE 7 and Java 8. The new release has entirely too many new things to hope to capture here so check out the release blog and then check out the What's New post
• Spring and Reactor ninja Simon Baslé just announced the Reactor Bismuth release…

We are pleased to announce the general availability of the 2.0.0.RELEASE of the Spring for Apache Kafka 2.0 version.

As mentioned in the 2.0 RC1 announcement, the 1.3 GA is also available supporting the Kafka 0.11.x.x client with Spring Framework 4.3.x applications.

They are available for download from the Release Repository and Maven Central:

repositories {
    maven { url 'http://repo.spring.io/release' }
}
compile "org.springframework.kafka:spring-kafka:2.0.0.RELEASE"

That was 6 months journey to bring a Java 8 and Spring Framework 5 vision for Spring for Apache Kafka project and here is…

On behalf of the Spring Data engineering team I am happy to announce the general availability of Spring Data Kay. It's the first major revision since Spring Data's inception in 2009 and thus packed with tons of features. Here are the most significant ones:

• Upgrade to Spring Framework 5.0, Java 8 and JavaEE 7 as baseline
• Revised repository APIs (better method names, Optional etc.)
• A revised repository composition model
• Support for reactive data access for Cassandra, Couchbase, MongoDB and Redis
• Addition of Spring Data Geode to the release train
• Use of nullability annotations and advanced runtime checks on those
• Kotlin support for null-safety and immutable data classes supported through Kotlin constructors
• General Java 9 compatibility

It's my pleasure to announce that Spring REST Docs 1.2.2.RELEASE is available from Maven Central, JCenter, and our release repository. My thanks to everyone who contributed to this release by reporting bugs and opening pull requests.

This maintenance release includes a handful of bug fixes and documentation improvements. It is a recommend upgrade for all Spring REST Docs users.

Dear Spring community,

It is my pleasure to announce that, after more than a year of milestones and RCs and almost two years of development overall, Spring Framework 5.0 is finally generally available as 5.0.0.RELEASE from repo.spring.io and Maven Central!

This brand-new generation of the framework is ready for 2018 and beyond: with support for JDK 9 and the Java EE 8 API level (e.g. Servlet 4.0), as well as comprehensive integration with Reactor 3.1, JUnit 5, and the Kotlin language. On top of that all, Spring Framework 5 comes with many functional API variants and introduces a dedicated…

It is my great pleasure to announce the GA release of Reactor Bismuth, which notably encompasses reactor-core 3.1.0.RELEASE and reactor-netty 0.7.0.RELEASE ?

With the release of Spring Framework 5.0 now just happening, you can imagine this is a giant step for Project Reactor :)

Like the bismuth crystal this release is intricate

 
The release contains a lot of changes and API polishing. For reactor-core you can find the exhaustive list in the release notes.

Important

There is a known (minor) issue with the reactor-core and reactor-test sources jars: They contain duplicate java source entries. See issue #887 for…

It's that time of year again! It's an exciting time for Java developers with Java 9 freshly out the door, with the promise of a faster release cadence for the language itself in the air.
If you're coming to the event, come check out talks with Pivotal / Spring Team speakers, and visit us at the booth for hands on lab stations for Reactive Spring, Microservices and Cloud Foundry!

Hi Spring fans! In this tip, we'll look at building a Kotlin-language reactive websocket-based application with the new web runtime and framework, Spring WebFlux, in Spring Framework 5. In order to keep things interesting, we also connect our websocket-backend to a frontend written using an Angular 4 and TypeScript.

I am pleased to announce that the 2.0.0.RC2 release candidate of Spring AMQP is now available in the Spring milestone repository.

Since the first release candidate the primary changes are:

• update to the new 5.0 version of the amqp-client library

• increase the default prefetch count in listener containers

A complete list of changes since RC1 can be found in the release notes.

Thanks to all the community members for their feedback and contributions!

The GA release will follow shortly after the Spring Framework 5.0 GA release.
