Kiro CLI v2.7.0 Changelog

This update is all about giving you a sneak peek at the future of Kiro. It matters most to developers who use the command line (the text-based interface on your computer) and want to try out new tools before they are officially finalized, without messing up the stable version they rely on every day.

What's new

• Early access to V3: You can now try out the next generation of the Kiro CLI. It runs on a "unified agent harness"—meaning the core software engine is now exactly the same across the Kiro terminal, desktop app, and web browser. Because they share the same brain, new improvements will roll out to all of them at the exact same time.
• Spec-driven development in the terminal: This means you can write out the rules and requirements for your code first, and the software will help guide the terminal to build it to those exact specs.
• Capability-based permissions: Instead of the tool having total access to your computer, you can now grant it specific "capabilities" (like only allowing it to read files, but not delete them) for better security.
• Enhanced hooks with standalone files: "Hooks" are custom triggers that run automatically when certain things happen (like running a test right after you save a file). These hooks are now getting their own separate file format, making them easier to organize and share.
• Tag-based agent configuration: You can now use tags (simple keywords) to quickly set up and customize how your automated coding agents behave.

Improvements

• The new V3 engine ensures that any feature or performance boost made to the Kiro desktop or web apps instantly improves the command-line tool, keeping everything perfectly in sync.

Fixes

• No specific bugs were mentioned for this release, as the focus is entirely on launching the V3 early access preview.

Breaking changes

No breaking changes in this release. Your current 2.x setup stays exactly the same until you specifically choose to turn on the V3 preview.
