Hi Spring fans! Welcome to another installment of This Week in Spring!

What a week it's been since we last talked. I was in Barcelona, Spain, for the amazing Spring I/O event there. It has become my favorite show, full stop. Just such an amazing experience. So many wonderful things going on there. So many amazing community members. So much joy. And a little sangria, being 100% honest. Then, after that, I went and spent a little time in a beautiful village south of Barcelona, then I went to the south of France for a little fun in the sun. Then I went to two cities in lovely Poland, where I was thrilled to see some of the amazing community members. And now I'm winging my way to Paris, where I'll be presenting at Devoxx France and seeing some of the community there. And, yes, I did just speak at the Paris JUG not more than a few weeks ago. Later this week, Friday, I'll be in amazing Athens for the Devoxx Greece show, too! If you're about, don't forget to say hi!
