## What changed


- **PR review**: New inline experience in Cursor 3 with Reviews (threads/comments), Commits (commit history), Changes (file tree + picker) tabs, reviewer status, and quick action pills
- **Build in parallel from plans**: "Build in Parallel" button identifies independent tasks and runs them simultaneously via async subagents, maintaining dependent step ordering
- **Split changes into PRs**: Quick action uses chat context to identify logical slices, creates backup snapshot, proposes split plan for approval
- **Pin skills as quick actions**: Pin frequently used skills as quick-action pills
- **Improvements**: Explore subagent model config (specific model, inherit, or disable), general model name support for subagents (e.g. `model: opus`), `/multitask` in editor, improved undo grouping, reduced long-chat jumpiness, predictable MCP connection with stale token cleanup on re-auth
- **Bug fixes**: Terminal interaction bugs in agents window, slash menu/input-approval regressions, MCP auth edge cases (401 handling, stale credentials), multi-repo environment selection/cache, cloud agent timing and hydration edge cases
