CDS with Spring Framework 6.1

Engineering | December 04, 2023 | ...

As a follow-up to the Runtime efficiency with Spring blog post, I am happy to share that our exploration of Project Leyden optimizations has led to some interesting discoveries regarding the JDK's little-used CDS ("Class Data Sharing") feature and has materialized into a new feature that we have been able to ship in Spring Framework 6.1.

Runtime efficiency with Spring (today and tomorrow)

From Spring Native to Spring Boot 3

Engineering | February 23, 2023 | ...

Today, we are finishing to transition the Spring support for building native executables from the experimental Spring Native project to the official Spring Boot GraalVM native image support.

In practice, that means we are archiving the Spring Native GitHub repository and moving it to the https://github.com/spring-attic organization. There will be no new release of Spring Native (based on Spring Boot 2.x) and we are encouraging all Spring Boot users to migrate to Spring Boot 3.x to leverage its official native support.
