Cursor 3.3: Streamlined PR Reviews, Parallel Builds, and Split PRs

TL;DR

• Cursor 3.3 introduces a brand new, integrated PR review experience.
• Plans can now be executed faster by building in parallel using async subagents.
• A new quick action allows users to easily split changes into separate Pull Requests.
• Users can now pin frequently used skills as quick-action pills for quicker access.

Cursor has just rolled out version 3.3, bringing a suite of significant enhancements designed to boost developer productivity. The headline features include a completely overhauled PR review experience, dramatically improved parallel build execution for development plans, and a handy new way to split large changes into smaller, more manageable Pull Requests. These updates aim to streamline workflows from code creation to final merge, making the development process smoother and more efficient.

The revamped PR review system is a major focus in this release. Developers can now manage Pull Requests entirely within Cursor, from their initial creation all the way through to merging. This integrated experience features a dedicated "Reviews" tab that displays inline threads and top-level comments, a "Commits" tab for a focused view of commit history, and a "Changes" tab equipped with a file tree for effortless navigation of extensive PRs. This comprehensive approach ensures all necessary review context is readily available without leaving the IDE.

Performance has also seen a substantial upgrade, particularly in how Cursor handles development plans. The new parallel build capability allows the platform to execute tasks simultaneously. By identifying independent parts of a plan, Cursor can run them concurrently using async subagents, significantly cutting down execution time. This means less waiting and more coding, a welcome improvement for any development team. You can learn more about these exciting updates on the Cursor Changelog 3.3.

Another key addition is the ability to split changes into separate PRs with a simple quick action. This feature leverages chat context to intelligently identify logical segments within your codebase, proposing a split that creates independent PRs unless dependencies necessitate otherwise. This helps maintain cleaner commit histories and simplifies the review process for complex features. For even faster access to your most-used functionalities, Cursor now allows you to pin frequently used skills as quick-action pills directly in the interface.
