Spring Boot 4 and Spring Framework 7 are major upcoming releases scheduled for 2025 that modernize Java development. Spring Framework 7 introduces built-in resilience features with annotations like @Retryable and @ConcurrencyLimit, enhanced API versioning support, Jakarta EE 11 compatibility, and requires JDK 17+ with JDK 25 recommended. Spring Boot 4 features modular architecture for smaller JARs, mandates Java 17+ baseline, integrates Micrometer 2.0 for better observability, and improves GraalVM native image performance. Both versions adopt JSpecify annotations for null safety, support Jackson 3.x, and focus on developer productivity improvements while maintaining compatibility with modern servlet containers.
