Hi, Spring fans! Welcome to another installment of This Week in Spring, and Happy Devnexus 2025 to those who celebrate! That's right sports fans, I'm off to awesome Atlanta, Georgia later today for Devnexus, one of the world's largest annual gatherings of Java community and luminaries alike. I'll be doing a talk on the latest-and-greatest in Spring Boot as well as another talk looking at Spring AI with the legendary Dr. Mark Pollack, founder of Spring AI. And, of course, I'll be soaking up all the other talks by Spring luminaries like Glenn Renfro, Jonatan Ivanov, Ken Kousen, Ryan Baxter…

• The runtime support has been revamped to avoid the dependency on an external library to topologically sort application modules, so that they can be traversed in dependency order (GH-1060). This allows assuming a stable module order in the application metadata file that – previously only created in AOT mode – is now also written when generating documentation (GH-1063). That in turn allows us to avoid the full bootstrap of an ApplicationModules instance at runtime, for example, to execute ApplicationModuleListener beans (GH-1062, GH-1065…
