Dear Spring community,

It is my pleasure to announce that Spring Framework 4.2.4 and 4.1.9 are available from repo.spring.io and Maven Central!

4.2.4 addresses a few regressions in the 4.2.x line and includes many fixes and enhancements, with no immediate issues remaining. 4.2.4 is a recommended upgrade for all 4.x users now. Please note that the 4.2.x line moves into maintenance mode at this point, with a low-volume 4.2.5 maintenance release scheduled for mid February.

4.1.9 is designed as the last release in the 4.1.x line, backporting applicable bug fixes as well as selected recent enhancements from 4.2.3 / 4.2.4. Note that this is the ultimate 4.1.x release: Your next upgrade step beyond 4.1.9 is the above-mentioned 4.2.5 in February, even for compatibility issues and…

Wow! It's December 15th, friends; many of us on this planet will soon celebrate a new year! Hopefully, you've done a better job than I have of getting all my new year's resolutions finished in time for 2016! If you haven't, at least catching up on the latest and greatest in the Pivotal community won't be insurmountable! Let's see what's happened this week..

Greetings Spring Community,

I hope you enjoyed my blog series on React.js + Spring Data REST. In that series, you got to build up a rich web app with hypermedia controls, conditional operations, messaging, and security.

To make things even better, that series has been bundled up and converted into a tutorial: https://spring.io/guides/tutorials/react-and-spring-data-rest/

Some key updates made along the way:

• require.js has been replaced with webpack as the JavaScript module builder/loader of choice
• The code is upgraded to ES6. This means that some of JavaScript's newest features like classes, arrow functions, and more are being used.
• bower has been replaced by npm as the package manager of choice
…

We are pleased to announce that Spring Batch 3.0.6.RELEASE is now available via Maven Central, Github and the Pivotal download repository. This is the 6th maintenance release for the 3.0.x branch of Spring Batch and addresses a number of minor bug fixes and enhancements. Many thanks to all of those who submitted the many pull requests that went into this release.

We look forward to your feedback in Jira, StackOverflow, or to me directly via Twitter @michaelminella.

It has sometimes been suggested that Spring and Spring Boot are "heavyweight", perhaps just because they allow apps to punch above their weight, providing a lot of features for not very much user code. In this article we concentrate on memory usage and ask if we can quantify the effect of using Spring? Specifically we would like to know more about the real overhead of using Spring compared to other JVM applications. We start by creating a basic application with Spring Boot, and look at a few different ways to measure it when it is running. Then we look at some comparison points: plain Java…

I'm delighted to announce that Spring REST Docs 1.0.1.RELEASE is available from Maven Central, JCenter, and our release repository.

This maintenance release includes a number of changes, including improved support for documenting attributes in XML payloads. An immediate upgrade is recommended for all Spring REST Docs users.

Dear Spring Community,

I'm pleased to announce the release of Spring Social Facebook 2.0.3.RELEASE. This is a maintenance release that addresses a few bugs, the most significant of which was a breaking change introduced recently in Facebook's Graph API which prevented connections and sign-in from working with Spring Social Facebook. In addition, the API binding has been adjusted to target Graph API v2.5.

Welcome to another installation of This Week in Spring! This week I'm in Chicago speaking to customers and then it's off to Washington D.C., and New York City for Cloud Native meetups! I hope you'll consider joining us at either event!

Time sure is flying! We're darned close to 2016!

Anyway, as usual, lots to cover so let's get to it!

• I really like the looks of this Caffeine local cache. It uses a pretty interesting algorithm to ensure near optimal cache hits It already features a JSR 170 (JCache) integration which means using it could be as simple as configuring the JCache adapter along with Spring's Cache abstraction.
• I really enjoyed Pivotal Labs' Brian Kelly's presentation, Spring Boot for Rails Developers. Check it out!
• 3Pillar has an interesting post on using Spring Boot with Docker
• Spring Framework lead Juergen Hoeller has revisited the Spring 5.0 roadmap in light of the recent 6 month delay for JDK 9
• Spring RestDocs lead, Spring IO Platform lead, and Spring Boot ninja Andy Wilkinson …
