This upgrade from Spring Boot 3.0.12 to 3.4.11 contains multiple breaking changes across several versions. Key Breaking Changes: Spring Boot 3.2: Support for Jetty 11 as an embedded web server has been removed in favor of Jetty 12. If you are using Jetty, you must upgrade and can no longer override the Servlet API version to 5.0. Spring Boot 3.3: This version upgrades to Prometheus Client 1.x, which includes breaking changes to metric names. It also upgrades to Flyway 10, which has been modularized and may require adding new database-specific dependencies. Spring Boot 3.4: Validation of nested @ConfigurationProperties now requires a @Valid annotation to cascade, which may prevent validation from running as it did previously. Recommendation: This is a significant upgrade. Review the release notes for versions 3.1, 3.2, 3.3, and 3.4 to identify all potential impacts. Pay close attention to dependency upgrades like Jetty, Prometheus, and Flyway, and validate your configuration properties. Source: Spring Boot Release Notes
