Spring Framework 4.3.5, 4.2.9 and 3.2.18 available now

It is my pleasure to announce that the Spring Framework 4.3.5, 4.2.9 and 3.2.18 maintenance releases are available now.

4.3.5 is a significant refinement release with 37 enhancements (including e.g. WebSocket support for the recently released Jetty 9.4) and several bug fixes, serving as the basis for the upcoming Spring Boot 1.4.3 release.

Please note that the 4.2.9 and 3.2.18 bug fix releases are the last in their respective line, with 4.2.x being superseded by 4.3.x now and 3.2.x reaching its EOL point. Going forward, we expect all users to upgrade to 4.3.5+ for further support.

This Week in Spring - December 20, 2016

Welcome to another installment of This Week in Spring! This week I’m in the winter wonderland of Toronto, Canada, hanging out with the amazing Pivotal Labs Toronto office and working with some of the largest financial institutions in all of Canada as they transition to Spring Cloud and to Pivotal Cloud Foundry. I love seeing seemingly large, lumbering companies run at startup speeds and crave it.

This week is the week of Christmas for some in the world, followed shortly by the western western new year. If you celebrate either (or both) of them, then, on behalf of the Spring team, let me wish you the happiest of holidays! I, for one, can’t believe we’re now less than two weeks away from 2017 (and with it, the beginning of the 7th year writing This Week in Spring!)

SpringOne Platform 2016 Replay: JDK 8: Lessons Learnt With Lambdas and Streams

Recorded at SpringOne Platform 2016.
Speaker: Simon Ritter, Azul
Slides: http://www.slideshare.net/SpringCentral/jdk8-lessons-learnt-with-lambdas-and-streams

Lambda expressions and the streams API add a more functional style of programming to Java; something developers have not really had in the past.

This session will start with a short summary of the key features of both Lambda expressions and streams before moving on to some real world examples of how to use them effectively, including a number of lessons learnt from trying to apply an imperative style of programming when it should have been functional.

SpringOne Platform 2016 Replay: Project Jigsaw in JDK 9: Modularity Comes To Java

Recorded at SpringOne Platform 2016.
Speaker: Simon Ritter, Azul Systems
Slides: http://www.slideshare.net/SpringCentral/project-jigsaw-in-jdk-9-modularity-comes-to-java-64849781

Project Jigsaw will bring modularity to the Java platform; something that will enable better security, performance and flexibility for deployment of applications. This talk will look at the fundamentals of how modularity in Java will work. Developers will need to understand that these changes go significantly further than just separating the standard class libraries into a number of discrete units.

SpringOne Platform 2016 Replay: Machine Learning Exposed!

Recorded at SpringOne Platform 2016.
Speaker: James Weaver
Slides: http://www.slideshare.net/SpringCentral/machine-learning-exposed-64845395
The term “machine learning” is increasingly bandied about in corporate settings and cocktail parties, but what is it, really? In this session we’ll answer that question, providing an approachable overview of machine learning concepts, technologies, and use cases. We’ll then take a deeper dive into machine learning topics such as supervised learning, unsupervised learning, and deep learning. We’ll also survey various machine learning APIs and platforms. Technologies including Spring and Cloud Foundry will be leveraged in the demos. You’ll be the hit of your next party when you’re able to express the near-magical inner-workings of artificial neural networks!
