Hi, Spring fans! Welcome to another wonderful, fanciful installment of This Month in Spring! It's been a busy month since we last spoke! I spoke at the Kotlin and Java User groups in Chicago with my friend and Gradle CTO Justin Reock. I spoke at Kotlin Conf in Amsterdam with my friend and Google Kotlin Program Manager James Ward. I spoke at Devoxx France. I spoke at the Great International Developer Summit in Bangalore, India. I was just this last weekend at the first Devoxx GR, in the sunny Mediterranean city of Athens, Greece. Uh, yah, this was a good'un, by the way. If you can get to it, you should. (Don't miss next year's installment if you missed this one!) And now, I'm in London, for one of my all-time favorite shows, Devoxx UK. (Are you going to Devoxx UK? Come find me! I'll be talking about Spring Boot 3, and it should be fun.) After this, I'm off to Germany where I may be appearing at a JUG near Wolfsburg (I'll keep you posted). Then, it's off to Spring IO in beautiful Barcelona, which is sure to be a ton of fun. Seriously, if you get one show in Western Europe, make it this one. And then, finally, it's off to ITKonekt in Belgrade. If you're in any of those places, come find me! We'll bring some Spring and have some fun along the way.
