Spring Blog

A critical piece of infrastructure, the Spring Artifactory instance repo.spring.io, lies at the heart of the Spring portfolio development work. Since 2013, JFrog, Inc. has generously sponsored the instance for the Spring developer community.

The Artifactory repository streamlines our project development by acting as a single location where Spring engineers can point their builds and by providing the community with early access to our snapshots and milestones.

Today, we are providing notice of some upcoming changes to the repository.

Dear Spring community,

On behalf of the Spring Framework team and our contributors, it is my pleasure to announce that Spring Framework 5.3 is generally available from repo.spring.io as well as Maven Central!

• What’s New in Spring Framework 5.3
• Upgrading to Spring Framework 5.3

Spring Framework 5.3 requires JDK 8 or higher and specifically embraces JDK 15 as the latest OpenJDK release, e.g. with binding support for record classes. As the last feature branch of the 5.x generation, the 5.3.x line is set up for an extended support phase, including JDK 17 LTS next year.

Dear Spring Community,

I am happy to announce the 4.8.1 release of the Spring Tools 4 for Eclipse, Visual Studio Code, and Theia.

quick reminder

• the Eclipse-based distribution of the Spring Tools 4 requires a JDK11 (or newer) to run on
