Hi Spring fans and welcome to another installment of This Week in Spring! Can you believe we’re already midway through the year?? Stunning.

This week I’m in San Francisco preparing for a video shoot next week and a joint presentatio with Google’s Ray Tsang at next week’s Google NEXT and tomorrow it’s off to Portland, OR, for the epic OSCON event where I’ll be doing a book signing at the O’Reilly booth on Wednesday and I’ll be doing a talk, Reactive Spring, on thursday. As usual, if you’re in the region and want to chat or grab a Voodoo doughnut, don’t hesitate to say hi!

We are pleased to announce that Spring Batch 4.1.0.M2 is now available on Github and the Pivotal download repository. Many thanks to all of those who contributed to this release!

What’s new?

Here are the highlights of this release:

• Simplify remote partitioning
• Add a new JSON item writer
• Add support for validating items with the Bean Validation API

Simplify remote partitioning

In the 4.1.0.M1 release, we created new APIs to simplify the configuration of a remote chunking step. In this milestone, we continued this effort to simplify remote partitioning through two new builders: RemotePartitioningMasterStepBuilder and RemotePartitioningWorkerStepBuilder.

On behalf of the team, I am pleased to announce the availability of Spring Cloud Stream Elmhurst.SR1 release train. This is the first maintenance release on the Elmhurst line and includes several bug fixes and minor enhancements in core Spring Cloud Stream (2.0.1.RELEASE), Kafka binder (2.0.1.RELEASE), and the Rabbit binder (2.0.1.RELEASE). Please take a look at the release notes for more details. The release can be found in maven central. Detailed descriptions can be found in the reference documentation.

Hi Spring fans! Welcome to another installment of This Week in Spring! This week I’m fresh of the amazing Spring Connect São Paulo event and speaking with some customers, and now I’m in beautiful Rio de Janeiro soaking up the winter rays by he beach, connecting with people in the community, and delivering a (virtual!) 2 day live training course for O’Reilly on building cloud-native Java-based applications. In less than two days I’ll be home for the first time in almost a month to celebrate the 4th of July. If you’re in America, let me be the first to wish you a happy holiday. As usual, we’ve got a ton of things to dive into so I’ll leave you to it. Let’s get going.
