" summary

Roadmap announces a Spring Framework 7 / Spring Boot 4 baseline with Jakarta EE 11, Kotlin 2, Jackson 3 and JSpecify nullability; recommendation to target JDK 25 for runtime benefits. Project Leiden AOT work on JDK 24 already cuts startup: AOT cache on JDK 24 yields 2.61s startup for PetClinic and prototypes drop to ~1.29s with AOT profiling plus Spring AOT; AOT repositories cut startup ~10% and render derived JPA queries as strings for up to 6x faster execution. Spring AI 1.0 ships with MCP support and a demo that updates a GitHub config to fix alert thresholds.
