Agents excel when the specs are known, like a compiler, browser, or language server. But the harder part is deciding what to build and how. We still haven’t seen agents make those product decisions end-to-end. We covered this live: https://jb.gg/sdd-post-blue

JetBrains: Essential tools for software developers and teams JetBrains is a cutting-edge software vendor specializing in the creation of intelligent development tools, including IntelliJ IDEA – the leading Java IDE, and the Kotlin programming language.

Download the new releases from jetbrains.com, install them through the Toolbox App, or use in-product updates. Looking forward to your feedback!

RustRover:
- Improves the quality of code analysis.
- Supports faster test execution with cargo-nextest.
- Supports the Call Hierarchy action.
- Makes it easier to access macro expansions with a dedicated gutter icon.

GoLand focuses on supporting Go 1.26, with new inspections and code modernization workflows. For DevOps scenarios, it also adds support for Terraform Stacks.

In Rider:
- You can work with standalone .cs files without creating a project.
- Game developers will enjoy iOS debugging for Unreal Engine and a new Unity Profiler integration.
- For C++ developers, we've added CMake project support and .NET mixed-mode debugging.

CLion simplifies migration from VS Code for c_cpp_properties.json users. It also supports DAP debugging via TCP and adds code insight for external CMake projects, ideal for embedded developers. This release also brings multi-architecture project support for Bazel projects.

In RubyMine, we've rewritten the code insight for classes, modules, and constants: the experimental symbol-based modeling engine greatly speeds up completion and Find Usages. We've also improved support for Ruby 4.0 and Rails 8.1, and we redesigned linter and formatter settings.

In PhpStorm, we've improved indexing performance by excluding framework-specific directories with frequently changing files. We've also extended PhpStorm’s MCP server so agents can access the IDE’s inspections, quick-fixes, search tools, and settings.

What's New in PyCharm 2026.1 YouTube video by PyCharm, a JetBrains IDE

In PyCharm, we've added support for a debugpy backend for lower overhead, more stable connections, and full asyncio support. This release also introduces Django 6 template partials and remote uv support via SSH, in WSL, or inside Docker. More in video: www.youtube.com/watch?v=U2tY...

In IntelliJ IDEA, Java 26 and Kotlin 2.3.20 are now supported. Spring Debugger now shows you the state of your Spring app without pausing its execution. And the command completion supports even more actions and use cases.

Next edit suggestions go beyond code completion and suggest applying related changes across the entire file, giving you a seamless Tab Tab experience. Available in AI Pro, AI Ultimate, and AI Enterprise subscriptions without consuming your AI quota.

We're redesigning our support for Dev Containers. Instead of running the full IDE backend inside the container and using remote development, you now only need a lightweight agent. The new support is enabled in IntelliJ IDEA and RustRover. Other IDEs will follow soon.

For DataGrip and database support in other IDEs, we're changing the query UX. You now have the choice between storing SQL queries in files and using query consoles. To share data source templates between IDEs, store them in your JetBrains Account.

The biggest change in WebStorm – and the JS/TS support in other IDEs – is the switch to the TypeScript language service for code insight and type inference, improving performance and accuracy. Project configuration now also follows TypeScript 6 defaults.

Core JavaScript and TypeScript Features Become Free in IntelliJ IDEA | The IntelliJ IDEA Blog Modern Java development often involves web technologies. To make this workflow more accessible and smoother, we’re making some core JavaScript, TypeScript, HTML, and CSS features – previously included

Core JavaScript support is now available for free in IntelliJ IDEA and PyCharm. This includes highlighting, navigation, completion, refactorings, and basic React support. Integration with all frameworks and debugging require a full license. Read more: blog.jetbrains.com/idea/2026/03...

We've updated an essential part of the code editing experience – the caret and selection behavior. Selections are now clearer, and you can choose between "Snappy" and "Gliding" modes for smoother, easier-to-follow caret movement.

Git worktree support makes it easier to manage multiple working copies of your repository. Run your agents in parallel and make sure they don't clobber your work, or create a new worktree for an urgent hotfix without affecting your main branch.

Thanks to ACP (the Agent Client Protocol), JetBrains IDEs are now a fully open platform for agentic development. Junie, Claude Agent, Codex - take your pick. And Cursor, GitHub Copilot, and many more can be installed via the ACP Registry.

Release season again: The 2026.1 versions of JetBrains IDEs are out. We have something for every dev! As usual, the new features also apply to plugins you can install in IntelliJ IDEA and other JetBrains IDEs.
Check out all the big highlights in the thread.

If every decision becomes a spec, large projects can end up with thousands of them. How do you manage that volume and ensure an agent reads only the docs relevant to the task? That’s still an open question. We covered it live: https://jb.gg/sdd-post-blue

Agentic AI breaks when it stays inside tools – it needs a system! We tried to map that system, but it couldn’t fit on one screen 😅 Zoom in to see how agents, tools, and delivery systems actually connect – and where JetBrains Central fits in. Full announcement: https://jb.gg/central

Agentic AI speeds up code production, but the challenge is execution and control.

JetBrains Central is an open system for agentiс development across the SDLC, with governance, observability, and controlled execution.

Early access starts in Q2 2026.

AI agents can generate unlimited amounts of code. Most of it is fine, but a few wrong lines can cause major errors or inefficiencies. Can a human reviewer spot them without getting fatigued? We covered this live: https://jb.gg/sdd-post-blue

Koog Comes to Java: The Enterprise AI Agent Framework From JetBrains | The JetBrains AI Blog Build reliable AI agents natively on the JVM. Koog for Java provides idiomatic builders, persistence, and observability – no Python microservices required.

If you build enterprise Java backends, adding AI agents shouldn’t mean spinning up a separate Python service. Koog for Java, an open-source, enterprise-ready AI agent framework for the JVM, has just been released.

When AI agents enter production systems, governance is put to the test. Policies and approval flows that worked in controlled environments often fall short in the real world. Orit Golowinski, Product Lead for Enterprise AI Safety, explains what organizationss can do about this: https://jb.gg/7we1k9
