Hi, Spring fans! Welcome to another rip-roarin' and exciting installment of This Week in Spring, wherein we look at the amazing week that was in the Spring community. And what a week it's been! In addition to tons of cool tooling and AI related stuff, this week saw the release of the first steps towards Spring Framework 7.0 and Spring Boot 3.5. Spring Framework 7.0, of course, is also the foundation upon which Spring Boot 4.0 will be based. So, that's exciting! Let's dive right in!

• Exciting news from Michael Minella: we're now publishing milestones to Maven Central.
• Spring Data 2025.1.M1 is out!. This is the first milestone in the 2025.1.0 line and has tons of nice new changes.

This release also finally does away with long-deprecated features like ListenableFuture. Spring Data JPA has seen major changes! Derived queries now use JPQL (not the Criteria API, as before), resulting in much faster performance thanks to Hibernate Query Structure Caching.
