On behalf of the team and everyone that contributed, I am pleased to announce that the fourth milestone of Spring Boot 2.3 has been released and is available from our milestone repository.

This release closes 99 issues and pull requests. Thanks to all those who have contributed.

Highlights of this milestone include:

• Support for liveness and readiness probes.
• Improved support for building OCI images.
• Improved support for building layered jars, including customization when using Gradle.

For a complete list of changes and upgrade instructions, please see the Spring Boot 2.3 Release Notes on the wiki and the updated reference documentation.

2.3.0.M4 is the last 2.3 milestone with 2.3.0.RC1 scheduled for release in three weeks' time. All being well, 2.3.0.RELEASE will then follow a couple of weeks after that in early May.

If you want to get started with 2.3 and try out the new features, you can bootstrap a new project on https://start.spring.io.
