1. Why Spring Boot 3 Matters Spring Boot 3.0, released in November 2022, represents a fundamental shift in the Java ecosystem. It is not merely an incremental update but a modern foundation for cloud-native, container-first applications. Built on Spring Framework 6, it requires Java 17 as a baseline and fully embraces Jakarta EE 9+ (replacing the old javax.* namespace).
