Cursor 3.3 Adds PR Review, Parallel Builds, and Auto-Split PRs
Cursor 3.3 shipped on May 7 with a new PR Review interface, async subagents that run independent tasks in parallel, and a quick action that splits one large change into multiple logically grouped pull requests.
Cursor 3.3 shipped on May 7, the next step after 3.2 introduced async subagents and worktrees. The headline additions push Cursor further into review and PR-shaping workflows, places where GitHub Copilot has had a head start.
PR Review With Tabs
The new PR Review interface organizes a pull request into three tabs: Reviews, Commits, and Changes. Inline threading and file navigation are built into the same view, so you can move from a comment to the relevant diff without bouncing between GitHub and the editor. This is Cursor catching up to Copilot’s review surface, and it lands in the editor where the rest of the work already happens.
Build in Parallel
The “Build in Parallel” action lets async subagents run independent tasks at the same time. The 3.2 release added subagents and worktrees as the foundation; 3.3 makes parallel execution a one-click thing rather than something you wire up by hand. Cursor also exposed /multitask in the editor for the same purpose.
Split Changes Into PRs
A quick action called “Split changes into PRs” takes one large set of modifications and divides it into logically independent pull requests. For anyone who has ever shipped a 40-file PR and watched the review queue go quiet for a week, this is the obvious shape for the feature. Whether the splits are clean enough to actually merge separately will depend on the change, but the framing is right.
Skills as Pinned Quick Actions
Skills can now be pinned as quick actions for faster access to ones you use often. It’s a small surface change, but skill discovery and reuse have been a friction point in agent-style editors generally.
Improvements and Fixes
The release also includes six improvements and five bug fixes. Notable items: Explore subagent behavior and model selection are now controllable via settings, subagent configuration accepts general model names like model: opus, and long-chat handling has been smoothed out to reduce jumpiness. On the fix side, MCP authentication now handles 401s and stale credentials more cleanly, multi-repo environment selection and cache issues were resolved, and cloud agent timing edge cases were addressed.
Why It Matters
Cursor has been racing up the SDLC stack: agents in 3.0, async subagents and worktrees in 3.2, and now PR review and PR splitting in 3.3. Each release narrows the gap with Copilot on the review side and widens the gap with Claude Code on the desktop-IDE side. If you live in PRs, 3.3 is worth opening today.
