On behalf of the team and everyone that contributed, I am pleased to announce that the first milestone of Spring Boot 2.4 has been released and is available from our milestone repository. This release closes over 120 issues and pull requests.

Please note the slight change in the format of the version. 2.4.0-M1 is the first Spring Boot release to use the new versioning scheme.

With Spring Boot 2.4, we have switched to a 6-month release cadence. All being well, you can expect to see 2.4.0 reach general availability in October or November.

Highlights of this first milestone include:

• Preliminary support for JDK 15
• Spring Batch 4.3 M1
• Spring Data 2020.0 M1
• Spring Framework 5.3 M1
• Spring Security 5.4 M1
• Filtered metric scraping with Prometheus
• Numerous other dependency upgrades

For a complete list of changes and upgrade instructions, please see the Spring Boot 2.4 Release Notes on the wiki and the updated reference documentation.

If you want to get started with 2.4 and try out the new features, you can bootstrap a new project on https://start.spring.io.
