[5.1.0] - 2026-06-08

Added

• Auto-update via electron-updater against GitHub Releases (default) or ConcreteInfo self-hosted feed.

• One-shot v4.4.1 → v5 settings migration with backup at settings.v4.bak.json.
• Local crash dump capture (cap 20, auto-prune) and a CrashReportModal.
• "Updates" section in Settings: channel picker, Check now, auto-check toggle.

5.0.0 - 2026-06-06

Added

• Complete React 19 + Vite + TypeScript renderer replacing the legacy vanilla-JS UI (Phases 1-9 of the React UI redesign)
• Native macOS/Windows/Linux menus with command palette and keyboard shortcuts
• Settings sheet with 5 tabs (editor, theme, keybindings, advanced, about) and 17+ persisted fields
• Modal layer with 13 modal kinds (export PDF/DOCX/HTML/Word, batch, settings, about, welcome, confirm, ASCII gen, table gen, find in files)
• 10 advanced tools: ASCII generator (figlet), table generator, Word export (.docx via docx lib), find-in-files (recursive regex), REPL (markdown snippet preview), print preview, zen mode (Esc exits), minimap, breadcrumbs-with-symbols, git status (porcelain parser)
• Sonner toast notifications at 4 wire points (file save, open file/folder, 4 export dialogs)
• 3 mount strategies: ModalLayer dialogs, App.tsx global overlays, editor/sidebar integrations
• ipc.file.writeBuffer for renderer-side binary file output (used by Word .docx export)
• ipc.file.search (recursive regex), ipc.file.gitStatus, ipc.print.show, ipc.app.showSaveDialog
• 305 unit + integration tests (vitest + React Testing Library)
• Per-package @radix-ui primitives (checkbox, dialog, select, switch, tabs, radio-group, scroll-area, slider, collapsible, label, context-menu)
• shadcn/ui (new-york style) primitives, manually pasted (CLI broken on Node 24)
• Feature-first main process decomposition: src/main/{files,menu,window,word-template,utils}/ + glue files

Changed

• BREAKING: Renderer is now React-only. The legacy src/renderer.js (5319 lines) and all vanilla-JS UI scripts/styles are removed.
• Main process decomposed from a 4311-line src/main.js into feature-first modules under src/main/
• New entrypoint: src/main/index.js (was src/main.js)
• src/index.html (1667-line legacy orphan) removed; renderer served by src/renderer/index.html (Vite root)
• IPC contract: handlers throw on error, safeCall catches → returns { ok: false, error }. result.ok is at top level, NOT nested in result.data.ok
• Settings store: useSettingsStore (zustand persist with zod validation), 17+ persisted fields
• Modal state: useAppStore.modal: ModalState discriminated union with 13 kinds; openModal uses TS conditional types to enforce prop requirements

Removed

• src/renderer.js (legacy vanilla-JS renderer, 5319 lines)
• 8 legacy stylesheets: src/styles.css, src/styles-modern.css, src/styles-concreteinfo.css, src/styles-sidebar.css, src/styles-zen.css, src/styles-welcome.css, src/fonts.css
• 5 legacy scripts: src/command-palette.js, src/print-preview.js, src/welcome.js, src/zen-mode.js, src/wordTemplateExporter.js
• 2 legacy HTMLs: src/ascii-generator.html, src/table-generator.html
• src/main.js (4311-line god file, replaced by src/main/index.js)
• src/index.html (1667-line legacy orphan at project root, replaced by src/renderer/index.html)
• 9 dead IPC channels from src/preload.js: toggle-command-palette, print-preview, print-preview-styled, open-ascii-generator, open-table-generator, show-ascii-generator, show-ascii-generator-window, show-table-generator, show-table-generator-window

[5.1.0] - 2026-07-23 - react-electron parity

Added

• Monospace font embedding — bundles JetBrains Mono + Fira Code TTFs and embeds the active font into PDF (xelatex fontspec), DOCX (post-pandoc zip patch with fontTable.xml), EPUB (--epub-embed-font + manifest), and HTML (woff2 base64 in CSS) exports. ASCII art and code blocks now render with the exact same font across machines.
• Monospace settings — get-monospace-settings / set-monospace-settings IPC, with monospaceFont (jetbrains-mono / fira-code) and monospaceLigatures (boolean).
• Renderer body-class toggle — useMonospaceClasses hook toggles mono-jetbrains-mono / mono-fira-code and mono-ligatures-on / mono-ligatures-off on document.body, driving --font-mono-active and --font-mono-feature CSS tokens.

Changed

• App renamed to Markdown Converter React (com.concreteinfo.markdownconverter.react, npm name markdown-converter-react, deb markdown-converter-react_*_amd64.deb) so the dev build coexists with the installed markdown-converter deb without single-instance lock conflicts.
• Window title shows Markdown Converter — React Dev in dev mode.
• download-tools.js pins Fira Code to release 6.2 with SHA-256 digests verified before atomic rename; downloads refuse to start on digest mismatch.

Security

• PdfFontHeader uses fs.mkdtempSync for an exclusive temp directory; the caller unlinks it after pandoc consumes the header (no racy Date.now()+pid filenames).
