"Spring Boot 4's modularization significantly improves startup times by reducing classpath checks for auto-configuration classes and producing smaller uber jars, although performance was not the primary driver of this change."
"Spring Framework 7 integrates features such as RetryTemplate, @Retryable, and @ConcurrencyLimit directly into the core framework, eliminating the need for extra dependencies."
"Users must select an appropriate HTTP API version strategy in Spring Framework 7, considering options like path, header, query parameter, or media type parameter due to the variety of HTTP servers and client stacks."
"Some members of the Spring team view AI coding tools as transformational and are actively researching ways to provide Spring-specific context to AI assistants."
Spring Framework 7.0 and Spring Boot 4.0 were released in November 2025, introducing REST API versioning, JSpecify annotations for null safety, and built-in resilience features. Spring Boot 4 migrates to Jackson 3 and modularizes the autoconfigure JAR. The framework maintains a JDK 17 baseline while adopting JDK 25, Jakarta EE 11, and Kotlin 2.2. Upgrading from Spring Boot 3 to 4 is manageable with support tools, and Spring Boot 4.1 is anticipated in May 2026.
