Features

• Extensions — a sandboxed add-on system. Install extensions per workspace to extend the app through six contribution types:
  • Panels in the left sidebar or bottom dock, custom file viewers/editors (fileHandler), language/syntax support, commands, file-tree context-menu items, and status-bar widgets.
  • A phased, sandboxed runtime exposing a controlled canv.* API; bottom-dock panels also surface in the pop-out window.
  • Install from a folder or a packaged file, with an install-consent step that discloses each extension's capabilities (workspace.write, activeDoc.read, net, ai, …) and the network hosts it may reach.
  • A two-layer trust gate — workspace trust plus per-extension trust — so opening someone else's workspace never runs code silently. Enable/disable, reload, crash recovery, and uninstall from the Extensions tab.
• Theme system overhaul. A proper theme catalogue replaces the old dark/light radio and accent picker:
  • New themes — Dracula, Synthwave '84, Solarized Dark / Light, Nord, Tokyo Night, Gruvbox, Dark 2026, and an Alucard light variant — chosen from a single dropdown in Settings → Appearance, plus a Match system option.
  • Semantic colour tokens across the whole UI (enforced by a canv/no-raw-color lint rule). The window titlebar overlay now syncs to the active theme and persists the last pair, so launch paints in-theme from the first frame.
• @-mention file picker in chat. Type @ in the chat box to fuzzy-find a workspace file and drop a reference to it into your message — full keyboard and click flow, with parity in the popped-out dock.
• Generative sites. Ask the assistant to build a small interactive view (timeline, board, chart) as a static site under .canv/sites/; it's registered in the Sites panel and served back at a local URL.
• Services & contributions architecture. A typed ICanvServices registry with a ServicesProvider, a contribution loader, and Disposable / DisposableStore primitives. App.tsx is split into focused contributions — theme/accent application, idle autosnapshot, app commands, the dock bridge, extension keybindings, and the quota-error toast.
• Editor & filesystem hardening. Inline selection tracking in the floating toolbar; per-cursor-move large-string allocations eliminated; debounced word-count with a gated recompute window; autosave widened to 5s. The filesystem layer now preserves EOL/BOM, refuses non-UTF-8 and oversize files behind a single MAX_OPEN_BYTES limit, and threads encoding through tool writes.
• Settings. A schema-driven settings form, an MCP server configuration UI, model pricing overrides, and a per-agent model picker.
• Removed: remote (SSH) workspaces. Remote-workspace support is gone — the renderer UI, Electron main support, the remote filesystem service, preload branches, and the ssh2 / ssh-config dependencies are all removed, and WorkspaceKind collapses to a single local kind. For remote files, use a file-sync tool (rsync, sshfs, your sync of choice) with a local Canv workspace on the synced folder.

Fixes

• Sidebar provider/model picker — empty-state now hides unconfigured providers and models, and the placeholder is shortened so it no longer clips.

Chores

• App version is interpolated from package.json into the welcome chrome (migration modal and empty-state) via Vite's define, so the version on screen always matches the build.
• Docs — the user guide was regenerated against 0.7.x/0.8.0: new pages for connecting an AI (including local Ollama) and for extensions plus the trust model; all remote-workspace content removed; appearance/themes and the chat @-mention picker documented.
