On behalf of the team and everyone that contributed, I am pleased to announce that the second milestone of Spring Boot 2.4 has been released and is available from our milestone repository. This release closes just over 250 issues and pull requests.

If you're trying this release with an existing Spring Boot 2.3 project, please note the slight change in the format of the version. 2.4.0-M2 is using our new versioning scheme.

Highlights of this second milestone include:

• Spring Framework 5.3 M2
• Spring Data 2020.0.0.M2
• An update to the way that application.properties and application.yml files are processed, including import support and support for volume mounted config trees.
• A a significant overhaul of the Neo4j support.
• 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.
