Dear Spring community,

It is my pleasure to announce that our fourth and last Spring Framework 5.0 release candidate is available now, aligned with Reactor 3.1 RC1 as well as yesterday's JUnit 5.0 GA, and serving as a foundation for the upcoming Spring Boot 2.0 M4!

Spring Framework 5.0 RC4 also comes with first-class support for the final version of the Servlet 4.0 API, provides fine-tuned integration with Hibernate Validator 6.0 and is up-to-date with Jackson 2.9.1 and Kotlin 1.1.4. Our dependency baseline is therefore almost complete, with just Reactor 3.1 GA and a few JDK 9 related updates…

On behalf of the Spring Data team, I’d like to announce the availability of Ingalls SR7 and Kay RC3 releases. Ingalls SR7 ships with over 40 issues fixed and Kay RC3 with exactly 90 issues fixed. Both are recommended upgrades for all users. Kay RC3 is the final release candidate before our GA at the end of September, i.e. in case you haven't already, it's the perfect time to give the new major version a test run.

For your convenience the service release is going to be picked up in the upcoming Spring Boot 1.5.7 release and Kay RC3 will be part of Spring Boot 2.0 M4.

You can find the complete list of issues fixed here for Ingalls SR7 and here for Kay RC3…

With the new Helm chart for Spring Cloud Data Flow for Kubernetes, there is now a much simpler way of installing the software.

Helm is a package manager for Kubernetes, similar to apt, yum or homebrew. It is very easy to install and it greatly simplifies installation of an application and its dependencies into your Kubernetes cluster. The application package contents and configuration is defined in a chart. When you install it you can override any default configuration values. Helm will install any required services in addition to the ones defined in the chart. For Spring Cloud Data Flow, you have three required services: MySQL and Redis are used as the stores for Spring Cloud Data Flow…
