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!

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

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…

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

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