Cursor 3.4: Full-Screen Tabs & Compact Chat Views

TL;DR

• Full-screen tabs let you expand Files, Changes, Canvases, PRs, and Terminals to fill your workspace
• Compact chat responses with three density levels (Compact, Balanced, Detailed) make agent conversations easier to scan
• 9 bug fixes across PR tabs, background tasks, cloud agents, and MCP/OAuth reliability

New

• Full-screen tabs — Expand any right panel (Files, Changes, Canvases, PRs, Browsers, Terminals) to fill the working area. Toggle with Cmd/Ctrl+Shift+M or the expand button in the panel header.
• Compact chat responses — Control agent tool-call density with three modes: Compact (minimal traces), Balanced (important steps), Detailed (full context). Read long conversations faster without losing context.
• Improved PR tabs — Clearer review states, better reviewer/thread visibility, and more predictable tab actions.
• Better long-chat scrolling — Smoother scrolling, improved undo grouping in prompt input, and better streaming behavior.
• Clearer status text — Background and resumed tasks now display more informative status updates.
• Environment/repo selection — Cleaner UI with better persistence when switching contexts.
• MCP auth improvements — Better token lifecycle handling for Model Context Protocol integrations.
• Faster search and navigation — Improved reliability in large workspaces.

Fixed

• PR tab bugs affecting branch lookup, header state, and diff loading
• Background task reliability issues including resume failures and incorrect status scoping on resumed subagents
• Cloud agents setup, state merge/persistence, and multi-repo identity bugs
• MCP/OAuth transient 401 errors, stale-token cases, and large-token handling edge cases
• Slash menu approval regressions, ask-question flow issues, and paste-chunk handling
• Keyboard shortcut bugs in modals and vim/emacs caret style leakage
• Hook invocation/path-length issues and Git prompt regressions
• Model-routing mismatches, proxy body normalization, and thought-chunk forwarding
• Webhook auth/hostname resolution, GHES installation persistence, and mirrored-repo behavior
