Dashboard / Flo

In this second installment of 1.3 release of Dashboard/Flo, we have addressed the core functionalities backing the streaming and task/batch operations.

Continuing the Angular4 based infrastructure upgrades, the streaming and task/batch workflows now include the modern look and feel and are packed with usability improvements as well.

Documentation, test-coverage, and webpack bundle-analyzer have gone through significant…

On behalf of the Reactor team, it is my pleasure to announce that reactor-core 3.1.0.RC1 has been released ?. This is a big last step towards GA release of 3.1 at the end of the month, the long term support version that will back Spring 5!

It is also complemented by various releases, all tied together in the Bismuth-M4 Release Train and BOM:

• reactor-test, reactor-extra, reactor-adapter and reactor-logback all made the cut to 3.1.0.RC1
• reactor-netty has seen significant updates and bug fixes in the new 0.7.0.M2 milestone
• reactor-kafka has been released in its 1.0.0.M4 milestone

In order to get this release, the best way is to use the BOM, as described in the reference guide here. Make sure to read the part about milestones (transposing it to Bismuth-M4…

We are pleased to announce the first release milestone of Spring Shell 2.x!

Two years in the making, Spring Shell 2 is a complete rewrite of Spring Shell, leveraging newer components (such as JLine 3) and applying better modularization. Spring Shell 2 is also built with Spring Boot in mind, making use of auto configuration and other boot features.

The internal architecture now uses a pluggable model to discover what methods to turn into commands, how to parse user input into argument values and how to handle return values. This is very similar to the approach taken by Spring MVC for example and allows extensions of the framework in ways that were not previously possible. Users of Spring Shell would typically not care though, only dealing with the new "standard" command API…

Spring Web Flow 2.4.6 was released earlier today containing a security fix. Applications that use explicit data bindings through the <binder> element in flow definitions are not affected. Those that do rely on default bindings should upgrade as soon as possible.

On behalf of the community I’m pleased to announce the release of Spring Session 2.0.0.M4. This release is focused primarily on refining WebFlux support. The highlights are:

@Configuration
@EnableSpringWebSession
public class HelloWebfluxSessionConfig {

  @Bean
  public MapReactorSessionRepository reactorSessionRepository() {
    return new MapReactorSessionRepository(new ConcurrentHashMap<>());
  }
}

Hot on the heels of the latest Spring Framework 5 release candidate, Spring Boot 2.0 M4 is now available from our milestone repository. This release closes 150 issues and pull requests and is a major step towards 2.0 GA. Thanks to all that contributed!

We are pleased to announce that the release candidate Spring Cloud Stream Ditmars.RC1 is available for use in the Spring Milestone repository. The release notes include relevant information about version compatibility with Spring Boot, Spring Cloud, Spring AMQP, and Spring for Apache Kafka.
