Hi Spring fans! Welcome to another installment of This Week in Spring! This week I'm in Nashville, TN, for a meetup presentation on Reactive Spring and then it's off to Kansas City, KS for a replay of the same talk. Both times I'll be joined by pal Mark Heckler. If you're in either of those cities, don't miss this!

I'm working on the next installments of Spring Tips: what would you like to see covered? Let me know on Twitter on @SpringTipsLive.

This week we have a truly massive good many things to look at so let's get started!

• Spring messaging and integration maestro Artem Bilan just announced Spring for Apache Kafka 2.0 M3. The new release includes, among other things, a new KafkaTransactionManager and according supportin the KakfaTemplate.
• Spring Session 2.0 M3 Released - Spring Security and Session ninja Joe Grandja just announced Spring Session 2.0.M3. This new release adds support for Spring WebFlux, and its WebSession and reactive programming in general.
• Not one to rest on his laurels, Christoph Strobl also announced the new release of Spring Data Kay RC1 and RC2…

Update: see also Spring Fu experimental project.

Since our original announcement (very well received by the community!) of official Kotlin support in Spring Framework 5, we have continued to work towards even stronger Kotlin support in conjunction with recent refinements in Spring WebFlux.

In order to demonstrate these features, and how they could be used together, I have created a new spring-kotlin-functional demo application which is a standalone Spring WebFlux application, developed in Kotlin, with Mustache template rendering, JSON REST webservices and Server-Sent Events streaming…

Dear Spring Community,

Spring Session MongoDB 2.0.0.M2 is released. It is based on:

• Spring Session 2.0.0.M3

• Spring Data Kay-RC2

• Reactor Bismuth-M3

• Spring 5.0.0.RC3

This is the first milestone with Reactor support, making it usable with Spring WebFlux.

In the meantime, you can get the bits today if you visit the project site, get the coordinates, and include the version number in your Spring Boot application.

Greetings Spring Community!

It is my pleasure to announce the first milestone release of both Spring Session Data Geode for Apache Geode and Spring Session Session Data GemFire for Pivotal GemFire.

Both artifacts can be downloaded from Spring’s libs-milestone Repository using Maven …​

  <dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session-data-geode</artifactId>
    <version>2.0.0.M1</version>
  </dependency>

Or with Gradle…​

  compile 'org.springframework.session:spring-session-data-geode:2.0.0.M1'

To use Spring Session with Pivotal GemFire, just switch the artifact from spring-session-data-geode to spring-session-data-gemfire…

On behalf of the Spring Data team, I’d like to announce the availability of Ingalls SR5 release.
It ships with over 40 issues fixed in total and is therefore a recommended upgrade for all users. For your convenience the service release is going to be picked up by the upcoming Spring Boot 1.5.5.
