On behalf of the community, I am pleased to announce that the Release Candidate 1 (RC1) of the Spring Cloud Edgware Release Train is available today. The release can be found in Spring Milestone repository. You can check out the Edgware release notes for more information.

Notable Changes in the Edgware Release Train

Renamed starters

A number of starters did not follow normal Spring Cloud naming conventions. In Edgware, use of the deprecated starter will log a warning with the name of the new starter to use in its place. Below is a table of the deprecated starters and their replacements


Spring Batch 4.0.0.M5 is now available

We are pleased to announce that Spring Batch 4.0.0.M5 is now available via Github and the Pivotal download repository. This release represents the fifth milestone for the Spring Batch 4.0 release. Many thanks to all that contributed to this release.

What’s new?

This milestone continues the work laid out in the previous 4.0.0 milestones. Specific updates include:

  • Dependency updates
  • FunctionItemProcessor
  • Continued updates to documentation

Dependency updates

As the dependency graph of Spring Boot 2 evolves, we have been updating our dependencies to be in line with them. This round includes updates to pull in the GA release of Spring Framework 5 as well as Spring Data Kay. Spring Integration 5.0.0.M7 was also pulled in for this release.


Spring Framework 5.0.1 available now

Dear Spring community,

It is my pleasure to announce that Spring Framework 5.0.1 is available now, as the first maintenance release in our Spring Framework 5.0 line.

In addition to addressing various user-reported bugs, we’ve applied minor refactorings to clean up unintended leftovers from the 5.0 GA release, e.g. for the reactive codec configurers.

This release upgrades Reactor to Bismuth SR3, based on Reactor Core 3.1.1, picking up essential fixes in Reactor Netty. Furthermore, AspectJ 1.8.12 brings some welcome performance improvements to Spring AOP’s pointcut expression evaluation at runtime.

Today I’d like to announce the first Release Candidate of the version 1.1 of Spring Integration for Amazon Web Services. Its artifact


is available in the Milestone Repository.

Thanks to everybody contributed!

Some highlights of the features since the previously announced Milestone 1:

This milestone refines a number of items from M4, and provides a number of notable new features:

  • JSON-B Support - We now offer support for JSON-B alongside our existing Jackson and Gson integrations. We continue to recommend Jackson as our default choice.
  • Session Actuator endpoint - Users of Spring Session can now view and expire sessions directly from the actuator.

On behalf of the Spring Data team I’d like to announce the eighth service release of the release train Ingalls. The release ships on top of the just released Spring Framework 4.3.12 and in preparation of the upcoming Spring Boot 1.5.8 released.

The release ships 42 (yay!) tickets fixed and is a recommended upgrade to all users of the Ingalls release train.
