This is a major upgrade from Spring Boot 2.x to 3.x, which introduces significant breaking changes and requires a careful migration. Highlights: Java 17 Baseline: Spring Boot 3.0 requires Java 17 as the minimum version. The application's JDK will need to be upgraded if it's on an older version like Java 8 or 11. Jakarta EE Migration: All dependencies have been migrated from Java EE to Jakarta EE. This requires changing package imports from javax.* to jakarta.* across the entire codebase. Source: Spring Boot 3.0 Migration Guide Recommendation: This upgrade requires significant developer effort, including a JDK upgrade and codebase refactoring for the new Jakarta EE packages. It is strongly recommended to follow the official migration guide and perform thorough testing before merging.
