Hi, Spring fans! As I write this, I'm winging my way to lovely London, UK, for the amazing Devoxx UK event! I'll be looking at the wide and wonderful world of Springdom. Then, from there, it's off to Code Remix in Miami. I'll also be speaking at the Tampa JUG while I'm there, so look out! After that, I'll be headed back to Europe—a wee bit further north this time—to Stockholm for the amazing JForum event, where I'll be doing a much deeper dive into all things Spring.

You know what I'm most excited about? You don't have to look far to figure it out—just check out the ol' Spring Calendar. Spring AI releases on May 20th! And then, a few short and sweet days later—which, by the way, I'll be spending in beautiful Barcelona, Spain at Spring I/O—out comes Spring Boot 3.5! Let's goooo!

Speaking of Spring I/O, I'll be there along with Spring legends Rod Johnson and Juergen Hoeller, co-founders of the project more than 20 years ago, doing a talk called From Beans to Boot, Aspects to AI. Do NOT miss this!

I'll also be doing a presentation with GraalVM founder Thomas Wuerthinger.

Spring Boot is a big release, but we've already got plenty of exciting GA versions of Spring Boot. Spring AI, on the other hand? Not so much. This is a big deal—years in the making! (Listen, if anybody could've predicted the rate of change in the AI space when we first started, I bet we would've released things a little differently…)

Anyway, my friends, we've got a ton of things to look at this week, so let's dive right in!

• Dynamic Tool Updates in Spring AI's Model Context Protocol
• On last week's installment of A Bootiful Podcast, I talked to Spring instructor Mary Ellen Bowman
• Spring Cloud 2025.0.0-RC1 (aka Northfields) has been released
• Spring AI 1.0.0-M8 Released
• Did you see the presentation that Dr. Mark Pollack, lead of Spring AI, and I put together for Devnexus a month or so ago?
• Similarly, have you seen my end-to-end tutorial on building Spring Boot applications?
• I also did a short video looking at Spring AI co-lead Christian Tsolov's review of Google's Prompt Engineering book
• Why does Spring use bubble sort (instead of something more efficient)? There's nobody better to chronicle this tale than Spring Framework legend Arjen Poutsma!
• This content on evaluation testing with Spring AI couldn't be more pertinent! Remember, you wouldn't deploy code to production without testing—so why would you deploy AI results you haven't evaluated?
• Good news, everybody! Instance main methods move from preview to final in JDK 25!
