May 2026: Focused on enabling Spring Boot 4 adoption in LangChain4j by adding Spring Boot 4 starter dependencies to the BOM, aligning with existing Spring Boot 3 entries, and updating documentation to reflect the new compatibility scope. This work reduces upgrade friction for customers and ensures parity across major Spring Boot versions.

Month: 2026-04 — LangChain4J: Focused documentation-driven delivery to enhance Spring Boot 4 integration support. The primary deliverable this month was updating the Spring Boot 4 integration documentation with new dependency naming conventions and explicit version compatibility notes. No major bug fixes were recorded; the emphasis was on reducing integration friction, improving developer onboarding, and aligning cross-module documentation for the Spring ecosystem. This work strengthens adoption readiness, reduces support overhead, and lays groundwork for smoother future feature rollouts across Spring Boot modules.

Monthly summary for 2025-11 highlighting delivered documentation alignment for Spring Boot 4 APIs and related documentation changes. The work reduces developer confusion and supports downstream adoption of the new RestTemplateBuilder and RestTemplateCustomizer package structure. Key driver: Spring Boot 4 package realignment migrating RestTemplateBuilder and RestTemplateCustomizer from org.springframework.boot.web.client to org.springframework.boot.restclient, with updated reference and Javadoc links. Impact: clearer guidance for users, improved onboarding, and alignment with codebase changes; potential reduction in support overhead as developers follow the updated docs.
