title: Tear-off Surfaces & Diff Review Hardening
---

> Any surface can now be torn off into its own window, Diff Reviews get smarter lifecycle handling, and a wave of stability improvements lands across the board.

## ✨ New

- Tear-off windows now support any surface — Chat, Workspace, Diffs, Kanban, and Plugin views can all be detached into standalone Electron windows

## 💎 Improvements

- Diff Review local-working-tree reviews stay in open status with a Live badge, reflecting their nature as live snapshots of uncommitted changes
- Diff Review agent fixes are now scoped to the revision they were created against, preventing stale planning runs from leaking into later revisions
- Composer drafts persist across tab switches
- Codex diagnostics now shows reset-credit count and deduplicates rate-limit cards
- Settings no longer appears in surface tabs
- Fuzzy model lookup uses token-aligned prefix matching for more accurate results

## 🐞 Fixes

- Fixed non-manual sessions not staying dimmed regardless of streaming state
- Fixed update staging directories not being properly isolated
- Fixed Windows installer server runtime packaging
- Removed health alert badge from tray title
