Dear Spring community,

On behalf of the core framework team, it is my pleasure to announce that the first Spring Framework 6.1 milestone release is available from repo.spring.io/milestone now. This release introduces the main themes for the 6.1 generation, with initial features for all themes present in 6.1.0-M1 already:

• Embracing JDK 21 LTS
• Virtual Threads (Project Loom)
• JVM Checkpoint Restore (Project CRaC)
• Data Binding and Validation, revisited

Note that Spring Framework 6.1 provides a first-class experience on JDK 21 and Jakarta EE 10 at runtime while retaining a JDK 17 and Jakarta EE 9 baseline. We also embrace the latest edition of GraalVM for JDK 17 and its upcoming JDK 21 version while retaining compatibility with GraalVM 22.3.

Check out our What's New page for details about the specific features in M1. Watch out for the first Spring Boot 3.2 milestone coming in July, based on Spring Framework 6.1. Please give 6.1 an early try and let us know how it goes, helping us to shape it up towards general availability in November!

Cheers, Juergen
