What's new

Agent skills

Skills give your agents reusable domain knowledge and instructions, making them more accurate and efficient when working with a given tech stack or topic. To help you get started quickly, IntelliJ IDEA now allows you to discover, install, and manage custom agent skills directly in the IDE.

Some of the most useful skills are already bundled in the IDE and marked accordingly in the skills manager.

Java 27

IntelliJ IDEA continues to provide support for the latest Java releases from day one, as well as early support for upcoming Java releases, for example, by allowing you to install early access builds directly from the IDE.

Logpoints and extended debugging experience

Every developer has used println for debugging at least once. But sometimes it is not the best approach. It can pollute the code, fail to get enough context from the print, and make identifying where it came from difficult. On top of all that, it doesn’t work inside libraries.

Logpoints offer a clean alternative and deliver dramatic UX and performance improvements. Built on top of non-suspending breakpoints, logpoints allow you to inspect internal application states and execution context, as well as send custom messages at runtime without modifying the source code. This approach also makes it possible to diagnose code behavior inside compiled third-party libraries.

Spring Security insights

With the Spring Debugger plugin in IntelliJ IDEA, it is now easier to verify endpoint behavior without changing your Spring Security configuration or restarting the application.

You can see Spring Security inlays near Spring MVC endpoints. They show how a route is protected, allow you to inspect where the effective rule comes from, and let you navigate to the corresponding security configuration. During a debug session, you can also test an endpoint with custom user details and roles or temporarily unlock it in the running debug context.
