Hi, Spring fans! Welcome to another exciting installment of This Week in Spring! It's April Fools day, so be wary of things you read on the internet, but it's also the 11th anniversary of Spring Boot 1.0, which was released this day in 2014! (that's not an April Fools). Happy birthday!

I'm in excellent Austin, TX, at Dr. Venkat Subramaniam's phenomenal Arc of AI show. I love this show! So many amazing people - many of whom also happen to be world-class speakers and engineers - converge in one place to synthesize their vantage point on "A.I." in one hour. Of course, I will be talking about…

Salut fans de Spring! In this installment I'm joined by the legendary Anthony Dahanne. If you've enjoyed success in production using Spring's built-in spring-boot:build-image capability, you've got today's guest Anthony to thank for it!

In 2025, we are evolving that story to bring more added value for Spring developers, either in Java or Kotlin. But before having a deeper look to the changes we are working on, let me explain why we do that and what are the expected benefits.
