Spring IO Platform Athens-SR6

I am pleased to announce that Spring IO Platform Athens-SR6 is now available from both and Maven Central.

This maintenance release upgrades the versions of a number of the projects in the Platform:

  • Spring Boot 1.4.7
  • Spring Cloud Connectors 1.2.4
  • Spring Data Hopper SR 11
  • Spring Framework 4.3.9
  • Spring Integration 4.3.10
  • Spring REST Docs 1.1.3
  • Spring Security OAuth 2.0.14
  • Spring Web Flow 2.4.5

The versions of a number of third-party dependencies have also been updated.

As mentioned in the release announcement for Spring Boot 1.4.7, it is expected that it will be the last release in the 1.4 line. As a result, it is also expected that Athens-SR6 will be the last release of the Platform in the Athens line. If you haven’t already done so, we advise you to upgrade to Brussels as soon as possible.

Spring Data Release Train Kay M4 Released

Spring Framework 5.0 RC2 available now

Dear Spring community,

It is my pleasure to announce that our second Spring Framework 5.0 release candidate is available now. This is a major revision of RC1, with refactorings in our new reactive facilities and in our new path pattern parser, as well as code style refinements all over the framework.

This release introduces a formal non-null API declaration for all of our packages, with explicitly nullable arguments and return values annotated as such now (instead of just javadoc’ed). Our nullability annotations are compliant with JSR 305 and specifically supported by IntelliJ IDEA and upcoming versions of Kotlin, with the potential to deliver particularly strong benefits for Kotlin users (which is why we’ve rolled them into 5.0 still). Note that we apply stronger null enforcement in some Spring APIs now, superseding our previously lenient null handling.

This Week in Spring - June 13th, 2017

Hi Spring fans! This week I’m in Redmond, hanging out with our friends and Pivotal partner Microsoft talking about Cloud Foundry on Microsoft Azure. As you may know, Microsoft’s Azure IaaS platform is the #2 most widely used cloud and it’s growing! It’s got more datacenters than the other two cloud vendors in more regions (including in Germany and China!) and a huge raft of services that support both Windows and Linux operating systems. There’s so much exciting stuff coming up including Azure Stack, which runs Azure on-premise, and the amazing integration between Azure and PCF. I’m looking forward to hearing even more about Microsoft Azure this week at CF Summit in Santa Clara, which is where I’ll be on Wednesday and then it’s off to Utah for the Utah JUG. Come out, join me, and say hi!
