Cursor 3: PR Review, Parallel Builds & Split PRs

TL;DR

  • New PR review experience with inline threads, commit history, and file navigation
  • Build in parallel — agents now multitask across independent plan steps simultaneously
  • Split changes into PRs automatically based on logical dependencies
  • Pin custom skills as quick-action pills for faster workflows

New

  • PR review experience — Reviews tab shows inline threads and top-level comments, Commits tab displays focused history, Changes tab adds file tree and picker for easier navigation of large PRs
  • Build in parallel — Click "Build in Parallel" to run independent plan steps simultaneously using async subagents while keeping dependent steps in order
  • Split changes into PRs — Quick action automatically identifies logical slices, creates independent PRs unless dependencies exist, generates backup snapshot, and proposes split plan for approval
  • Pin skills as quick actions — Save your most-used custom skills as quick-action pills for instant access
  • Explore subagent control — Configure which model Explore subagents use, inherit parent agent model, or disable them entirely from settings
  • /multitask command — Run async subagents in the editor to parallelize requests instead of queuing them sequentially

Fixed

  • Terminal interaction bugs in agents window — editing shortcuts and approval overlays now work correctly
  • Slash menu and input-approval regressions resolved
  • MCP auth edge cases including transient 401 handling and stale credential cleanup
  • Multi-repo environment selection and cache issues
  • Cloud agent timing and hydration edge cases that degraded reliability

Improvements

  • Prompt input undo grouping now feels more natural during edits
  • Long-chat handling improved with reduced jumpiness and unexpected behaviors
  • MCP connection behavior more predictable with explicit stale token cleanup on re-auth
  • General model names now supported for subagent configuration (e.g., model: opus always uses newest Opus)
