IntelliJ IDEA 2025.2 is the latest release from JetBrains, introducing a range of new features and improvements to enhance developer productivity. Key highlights include enhanced AI-assisted workflows with improved AI Assistant capabilities, now available for free. The AI Assistant supports a wide array of languages, including SQL, YAML, JSON, and Markdown, and the Junie coding agent is now 30% faster thanks to the Model Context Protocol.
Privacy-minded users will appreciate the offline AI-powered code completion for Java, which eliminates the need for cloud APIs while ensuring privacy. This update also brings support for Java 25 in its Long-Term Support (LTS) version, including early access builds, alongside full compatibility with Maven 4.
Spring developers will benefit from major improvements, such as enhanced debugging tools, a new debugger plugin, and support for Spring Modulith. Virtual thread debugging capabilities further streamline the development process. Users of the Ultimate edition gain real-time runtime insights, enhancing the Spring development experience.
For remote development, significant improvements make it as responsive as local development, thanks to reworked WSL integration for better performance with Maven and Gradle projects. Continued evolution of the Kotlin K2 mode with new inspections and refactorings, and performance optimizations including a reworked terminal, enhance the overall developer experience. Additionally, native Bazel support and quality upgrades for Kotlin Notebook make this release a robust tool for modern software development.
JetBrains has also redesigned their approach to updates, offering separate ‘What’s New’ and ‘What’s Fixed’ communications, providing clearer insights into the improvements. As IntelliJ IDEA 2025.2 rolls out, developers will find a focus on stability and quality enhancements across various facets of their workflow.
