Java Annotated Monthly – December 2025 | The IntelliJ IDEA Blog

The December 2025 edition of Java Annotated Monthly highlights significant updates in the Java ecosystem, including the announcement of JEPs for future Java releases and the introduction of Spring Framework 7 and Spring Boot 4, which offer new features like API versioning and enhancements to HTTP service clients. This issue also features content curated by Siva Katamreddy, a Developer Advocate at JetBrains, who shares insights into building cloud-native applications. Noteworthy changes in Spring Boot 4 include modularization of the spring-boot-autoconfigure JAR to reduce the runtime footprint, and Dan Vega's video series provides an overview of these updates. IntelliJ IDEA 2025.3 now supports these Spring advancements, enhancing its integration with tools like Spring Data JDBC. Additionally, the release of Spring AI 1.1 GA introduces a simplified annotation-based programming model for building GenAI-powered applications. The publication covers a variety of topics including Java tutorials, Kotlin updates, AI developments, and industry trends, along with announcing upcoming conferences and events for developers.
