#SpringCloud 2025.1.0-RC1 will be released early next week and will be compatible with Spring Boot 4.0.0-RC2.

I am happy to share that we have released Spring Boot 4.0.O-RC2.

RC2 adds some fine tuning for Spring projects that had to do a second RC as well. We've also swiftly reacted to changes in the community: Jersey released a 4.0.0 that is compatible with Jakarta EE 11 so its support was reinstated.
Spring Boot 4.0.0-RC2 available now

The backend work for this feature was done by Sijun Yang (github.com/YangSiJun528), the frontend work was done by Yusuf Özacet (github.com/devysf).

Thank you both very much!

A new feature dropped on start.spring.io!

Because you all love YAML so much, we've added radio buttons to switch the configuration format from properties to YAML. Hope you brought a ruler and don't live in Norway!

I am happy to share that we have released Spring Boot 4.0.O-RC1.

This release candidate concludes our modularity efforts, migration to Jackson 3 with support for using Jackson 2 in a deprecated fashion, and more.

Please give it a try and let us know what you think!

Thank you to everyone who joined our session on boosting Java performance with Project Leyden, Java 25, and Spring Boot! 🚀

@0.5ritter.de and I hope that you will apply the optimizations and tips we shared today. The slides we used:
www.slideshare.net/slideshow/su...

#JDK25 #SpringBoot #Performance
Supercharge your JVM performance with Project Leyden and Spring Boot
Many modern applications and tools rely on Java. Yet, their startup time and time-to-peak performance remain challenging, especially for microservices and Kubernetes workloads that require fast scaling and responsiveness. Project Leyden, an ambitious OpenJDK initiative, aims to overcome these performance bottlenecks. In this session, Ana and Moritz showed how you can take advantage of Leyden’s optimizations using Java 25 and Spring Boot. You also got practical techniques you can apply today, along with a peek into the ongoing work inside Leyden and what that means for the performance of your Java application. - Download as a PDF or view online for free
