What's new

AI Agents and ACP

In addition to Junie and Claude Agent, you can now choose more agents in the AI chat, including Codex. Also, Cursor and GitHub Copilot, along with dozens of external agents, are now supported via the Agent Client Protocol. With the new ACP Registry, you can discover available agents and install them in just one click.

Support for Java 26

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.

Unlike Java 25, Java 26 doesn't introduce any new stable language features, but it does bring previews for pattern matching and lazy constants, which are already supported in IntelliJ IDEA.

Runtime code insight for Spring applications

Spring Debugger now allows you to see the state of your Spring application directly in your code, without pausing its execution. This means no more guessing and no more jumping to the project tree to understand wiring, profile configuration, and the environment. You can detect wrong bean injections, test secured endpoints, and review the application configuration in the running code, saving you time and money on static code analysis.

Native AI support for databases

The AI chat integration for Junie, Codex, and Claude Agent now offers full, native support for your connected databases. Whether you're using Junie's autonomous planning to refactor data layers or leveraging the reasoning of Claude Agent, you can now query, analyze, and modify your database state using natural language right from the IDE.
