5.0.0 - 2026-06-06

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

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

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

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
