On behalf of the Spring, Apache Geode and Pivotal GemFire communities, I am pleased to announce the release of Spring Boot for Apache Geode & Pivotal GemFire (SBDG) 1.0.0.M4.

Special appreciation goes out to @starbuxman for his invaluable feedback after SpringOne Platform 2018. And, if you have not seen Josh’s Spring Tip video on Apache, please check it out.

What’s New

Among a few minor updates, Milestone 4 adds the following new capabilities:

On behalf of the team and everyone who has contributed, I'm happy to announce that Spring Initializr has been updated and is now available on start.spring.io.

UI changes - listening to your feedback

While start.spring.io seems like a very simple service, generating applications with a simple HTML…
