- stores/versions-store.ts, hooks/use-session-manager.ts,
lib/session-storage.ts: remove the diagramHistory conversion layer,
the localStorage chat migration and the empty templates store
- stores/canvas-store.ts, lib/drawio/editor-bridge.ts: remove the
pages list nothing read
- components/chat/chat-engine.tsx: use the context's chartXMLRef and
latestSvgRef instead of local copies, subscribe to one settings field,
stop prefetching quota limits (lib/use-quota-manager.tsx takes the
values from the 429 body), readDiagramFile delegates to the MCP
loader (which now strips XML prologs and accepts <svg:svg>)
- contexts/diagram-context.tsx: one requestTaggedExport path for
thumbnails, validation, fetch and save; fetchDiagramXml replaces
handleExport plus the exported resolver map
- hooks/use-validate-diagram.ts and app/api/validate-diagram: plain
fetch returning JSON instead of a streamed object nobody consumed
- hooks/use-diagram-tool-handlers.ts: drop the DEBUG blocks; canvas
vars inheritance lives in placeOnPage (lib/diagram-pages.ts)
- lobby-hero, icon-button, drawio-frame: remove unreachable branches
and unused props
* feat: redraw the app icon on a white tile with shorter bottom boxes
Same org chart shape as before, redrawn as a vector so edges are sharp.
The white tile keeps the icon visible on dark docks, taskbars and tabs,
so dark mode now uses the same image and favicon-white.svg is removed.
The desktop icon is now 1024x1024.
* chore: add SVG sources for the app icon and favicons
resources/icon.svg renders resources/icon.png; resources/favicon.svg renders
the favicon .ico and .png files.
* fix: add a title to the icon SVG sources for the Biome a11y check
Start screen
- The five examples are one row of picture tiles (title under the picture); the old cards cut their descriptions off with an ellipsis
- "Open .drawio file" leaves the example grid and sits with "Start with a blank canvas" below it, both as outlined buttons
- The "Paper to diagram" example gets a thumbnail of its result (public/paper_demo.svg) like the other four
- The caption says what happens: examples use saved answers, so they appear at once and do not call the AI
- Shorter lede
Chat panel
- The version card's "</>" icon button becomes a "Show XML" text link in the summary line; the summary runs under the title row, so Undo is the card's only button
- Settings uses the gear icon; new diagram uses a file-plus icon instead of the pen that reads as "edit"
- The message box has the same side padding as the message column
Copy
- The model picker says "Server model" instead of "Default" when the server's model is in use
- The theme description no longer claims the diagram always stays on a white sheet (the canvas follows the theme)
- en, zh, ja and zh-Hant dictionaries updated together
The canvas now fills the window and the chat floats on its right. draw.io is
served from our own origin (public/drawio, downloaded at build time and
checked against the release's SHA-256), so the app can drive the editor
directly:
- every AI change becomes a version card with a thumbnail; compare, restore
or undo it, and Ctrl+Z on the canvas takes an AI change back in one step
- shapes the AI just changed are highlighted on the canvas
- selected shapes appear as a chip and are sent to the model
- draw.io's own simple UI: its toolbar, menus (auto layout, Mermaid, CSV
import) and page tabs; the shape library starts closed
- new start screen, session rename and switcher, open .drawio files
- settings split into Models & keys, Appearance, Advanced and About
- Bedrock in the model settings also takes an API key instead of access keys
- phones switch between canvas and chat
- dark mode uses draw.io's own dark mode, with neutral greys around it
With an external draw.io (NEXT_PUBLIC_DRAWIO_BASE_URL) the features above
that need same origin are off.
The chat logic moved from the 1500-line chat panel into a chat engine plus
small UI components; zustand holds canvas, versions, settings and UI state.
