v0.4.0-beta.1

What's New

Canvases

• Build documents, tables, charts and App interfaces as one kind of canvas, backed by editable React source and shown in a single canvas library.
• Create canvases with the built-in Canvas Authoring app in Code mode: start from a document, report or dashboard template, preview with real App data, inspect the rendered result and activate a version when it is ready.
• Give canvases their own icons and colors. App changes made from a canvas are confirmed one at a time and recorded.
• Existing canvases are converted to editable source on upgrade. Images that are no longer available become a placeholder instead of blocking the upgrade.

New Desktop Layout

• A redesigned shell with an activity rail, and matching sidebars, home pages and breadcrumbs for conversations, canvases, apps, scheduled tasks and projects.
• Settings open as a full page with grouped sections, one content width and consistent headings.
• Mentions for apps, skills and canvases share one @type/id(name) format.
• Conversations keep your reading position while panels resize or collapse.

Models and Reliability

• New model presets: Claude Fable 5.1, Opus 5.5 and Sonnet 5.5; GPT 6.1 Sol and GPT 6 Luna; GLM 5.3. OpenRouter cost estimates assume an 80% cache hit rate.
• Live updates resume after a slow connection catches up, cancelled turns are recorded as cancelled, and daemon token checks and attachment responses are hardened.
• Electron 44.4.5, Go 1.26.6 and patched dependencies.
• The database moves from schema v24 to v26 with an automatic backup first. After upgrading, 0.3.10 can no longer open the data.
