This is a major version upgrade from Spring Boot 2.x to 3.x, which introduces significant breaking changes and requires a major migration effort. Highlights: Java 17 Required: Spring Boot 3.0 requires Java 17 as a minimum version. Applications running on Java 8 or 11 must be upgraded. Jakarta EE Migration: All dependencies have been migrated from Java EE to Jakarta EE. This requires changing all javax.* package imports to jakarta.* throughout the application, which will cause compilation failures until addressed. Configuration & API Removals: Numerous configuration properties have been renamed or removed, and APIs deprecated in Spring Boot 2.x have been removed. Source: Spring Boot 3.0 Migration Guide Recommendation: This upgrade cannot be merged without significant developer intervention. A dedicated migration plan is required to address the JDK requirement, package name changes, and other breaking API updates.
