Maria Kosukhina

March 25, 2026

IntelliJ IDEA 2026.1 is here, and it comes packed with an array of new features and enhancements to elevate your coding experience!

You can download this latest release from ourwebsiteor update to it directly from inside the IDE, via the freeToolbox App, or using snap packages for Ubuntu.

As always, all new features are brought together on the What’s New page, with detailed explanations and demos.

In addition to the What’s New page, our developer advocates got together to discuss and demonstrate the key updates. If you prefer watching to reading, check it out.

IntelliJ IDEA 2026.1 brings built-in support for more AI agents, including Codex, Cursor, and any ACP-compatible agent, and delivers targeted, first-class improvements for Java, Kotlin, and Spring. The release also advances IntelliJ IDEA’s mission to provide support for the latest languages and tools from day one.

_Please note that some AI features may work differently or be unavailable in your region. Learn more._

Any agent, built-in:

• ACP Registry: Browse and install AI agents in one click.
• Git worktrees: Work in parallel branches and hand one off to an agent while you keep moving in another.
• Database access for AI agents: Let Codex or Claude Agent query and modify your data sources natively.

Intelligence in the platform:

• Quota-free next edit suggestions: Propagate changes throughout a given file with IDE-driven assistance.
• Spring runtime insight: Inspect injected beans, endpoint security, and property values without pausing execution.
• Kotlin-aware JPA: Detect and fix Kotlin-specific pitfalls in Jakarta Persistence entities.

First-class language support:

• Java 26: Enjoy day-one support, including preview features.
• Kotlin 2.3.20: Enjoy day-one support, including experimental features.
• C/C++ in IntelliJ IDEA: Access first-class C/C++ coding assistance for multi-language projects.
• Support for JavaScript without an Ultimate subscription.

Productivity and environment:

• Expanded command completion, now with AI actions, postfix templates, and config file support.
• Better performance for large-scale TypeScript projects.
• Native Dev Container workflow: Open containerized projects as if they were local.

Along with new features, 2026.1 delivers numerous stability, performance, and usability improvements across the platform. These are described in a separate What’s Fixed blog post.

As always, your feedback plays an important role in shaping IntelliJ IDEA. Tell us what you think about the new features and help guide future improvements.

Join the discussion on X, LinkedIn, or Bluesky, and if you encounter any issues, please report them via YouTrack.

For full details of the improvements introduced in version 2026.1, refer to the release notes.

Thank you for using IntelliJ IDEA. Happy developing!
