Hi, Spring fans! Welcome to another illustrious installment of This Week in Spring! It’s Thanksgiving week here in the United States. Thanksgiving is traditionally celebrated with friends and family every fourth Thursday of November, gathered around a table full of food and, usually, a giant stuffed turkey. When celebrated well, it’s a time to come together and revel in gratitude for life’s good fortunes. And so, in that spirit, my friends, I want to remind you — and I’m sure I can speak for the entire Spring team here, too! — that we are so grateful for you. The community is the most amazing…

This Week in Spring - November 18th, 2025

Hi, Spring fans! I'm thrilled to be in New York City for an exciting week of joint presentations on Spring AI + Bedrock and Spring Boot with the legendary James Ward.

First up: we'll present a workshop at the AI Native Dev Conf today, then speak at the Garden State JUG tonight, then deliver a talk tomorrow at the conference, and finally speak at the New York Java SIG tomorrow night. It might be cold out, but we're bringing the heat!

This past week saw Spring Framework 7 go GA, and with it a whole release train of new releases that will eventually culminate in Spring Boot 4. Once Spring Boot 4 is released, Spring AI, Spring Modulith, and Spring Cloud will all be able to release as well.
