Release v1.7.1 · globalroo/markdown-viewer

What's New

Error boundary — React crashes now show an error screen with stack trace and a recovery button, rather than a blank white window. Uncaught renderer exceptions are surfaced and logged instead of silently wrecking the app.
Fewer ways to crash on close-all-tabs — Closing the last tab now fully resets edit state (editMode, editContent, editDirty, editFilePath) so no orphaned draft data can trigger a subsequent render crash.
Cmd+W no longer closes the whole window — preventDefault() now fires unconditionally on Cmd/Ctrl+W, ahead of the settings/editing guards, so Electron never falls through to native "Close Window". Cmd+W still closes the active tab while typing in the editor.
Print from edit mode works reliably — Replaced an inline display: none on the preview with a CSS class so the @media print override wins the cascade cleanly. Prints the rendered preview instead of the editor textarea.
10 new close-all-tabs E2E tests — Covers collapsible mode, mixed fold states across files, links panel, mermaid diagrams, themes, rapid close, and edit-mode scenarios.

Four rounds of multi-agent review (Gemini + Codex + Claude) with ship/no-ship verdict. Unanimous SHIP after addressing two findings:

Codex caught that the original Cmd+W preventDefault() was bypassed by the settingsOpen and isEditing early returns — fixed by hoisting it above the guards.
Gemini caught that hoisting it naively would silently discard unsaved drafts while editing — fixed by whitelisting the tab-close path in the isEditing block.
