This Week in Spring: Releases, Kotlin Support, and Spring Boot for Apache Kafka

Hi, Spring fans! Welcome to another installment of This Week in Spring! I’m in beautiful Krakow for the epic Geecon show, and then, I’m off to the spectacular Barcelona, Spain, for the Spring I/O show. I hope to see you in both locations! It’s sure to be fun. Next week, it’s going to be even more crazy! I’m off to Zurich, Switzerland, for a visit with some customers, and then, it’s off again to Paris, France, for the Spring One Tour event there. Next, I'm off to Minsk, Belarus, for the VOXXED Days Minsk show (my first time there! I’m so excited!). And then, right after that, I'm off to Barcelona, Spain, for JBCN. If you’re at any of these events in the next 12 days, I’d love to chat!
