Others join from the desktop app (invite links open it) or from the browser build. See [`docs/collab-protocol.md`](docs/collab-protocol.md).
 - **A server of your own (preview):** `figcraft-server` keeps a team's files, publishes them from the app (File ▸ Publish to server…, or Share ▸ Online with your server in Preferences) and hands out share links and join codes that let people edit or only view; files survive restarts and apps reconnect where they were. No accounts yet: links are the access.

 | Date | Change | Summary |
 |---|---|---|
+| 2026-10-20 | minor | Layer data reads back (#879): `node.get` (the command, the control method and MCP `get_node`) and `document.inspect` report a layer's or page's `pluginData` as `{key: value}` when it has any, so a tool that keeps state in a file with `node.set {props: {pluginData}}` can read it on its next run (`plugin_data_tests`). Numbers unchanged |
+| 2026-10-20 | minor | Measuring while nudging (#894): with Alt held over another layer, the arrows nudge the selection (Shift: the big step) and the distances follow every nudge (Alt+arrows used to do nothing); while measuring, the selection's handles and size label hide and both layers keep their outlines (`measure_nudge_tests`). Numbers unchanged |
+| 2026-10-20 | minor | Release fonts (#885): the web release embeds craft-fonts again (Inter), so the browser version draws text and lists fonts; it had none since releases moved to the shared workflow. The craft-fonts pin goes back to the commit with the Latin manifest (the Georgian change had moved it to one without Inter, which would have failed the next release). Numbers unchanged. |
 | 2026-10-17 | minor | Community batch #753 (10 PRs): Selection colors for mixed selections (#403); smart-selection spacing fields and canvas handles (#402); a Present tab with device and scale controls (#537); adding auto layout to an empty frame keeps its size (#369); `node.set` applies auto layout keys to frames only and warns about font styles a family lacks (#603); canvas images on whole device pixels (#359); Adwaita window controls on Wayland without server decorations (#592, not run on GNOME or KDE by the maintainers); the keyboard shortcuts panel closes on the home screen (#548); macOS paste modifiers in tests (#750); credits column tests (#347). `cargo xtask parity` re-run: 212 / 212 menu items (100%; the catalog gained View ▸ Full screen with #227 on 2026-10-14), 561 commands. Language table re-measured from the catalogs (2,272 entries): the drafts read 95–99% (strings added since 2026-10-12 show English), Indonesian has a draft (99%; it read none), and Russian, Swedish (its command labels from #599), Turkish and Czech are listed with their counts. Per-area parity rows for the day's landings in `docs/gaps.md`, `target-app-parity.md` and the area docs. Numbers unchanged |
 | 2026-10-17 | minor | Control channel while the window is minimised (M8, #720): a minimised or covered window answers every request that acts on the app's state (edits, `ui.inspect`, `ui.pointer`, `ui.key`, `ui.type`, `ui.set`, `app.quit`…) without drawing, and what needs a drawn frame (`ui.screenshot`, `ui.input`, `window.new`) is an error at once; before, those waited up to 60 s and held up every later request on the connection (an attached agent's `inspect_ui` or window screenshot stalled until the window came back). Measured on Windows 11, minimised: requests ~100 ms each (eframe wakes a minimised window at most ten times a second; ~2 ms on screen), a window screenshot fails in ~100 ms instead of 60 s, idle CPU 0. Numbers unchanged. |
 | 2026-10-17 | minor | Community fixes from #524 up (batches #727, #728, #733, #735, #736 and #729; 55 PRs) and a crash guard. `.fig` import: explicit instance identity, overrides by key, text style precedence, grid track sizes, slot content, connector labels, skip ink, paragraph options and hanging lists, list start numbers, vertical trim, per-point stroke joins, text on a path, image adjustments and embedded images; large files open within budgets from the file's own size; an import report after opening; imported bytes stay out of the command journal. Files and paste: save a copy as `.fig`; Cmd/Ctrl+V pastes images copied in other apps and layers copied from another design app (`edit.pasteDesignLayers`); paste over and paste properties; clipboard reads on Linux and the BSDs time out after 2 s. Editor: live font preview on hover; Shift+I and Resources open Assets; Shift-drag moves the selection; thin strokes take a nearby double-click; dropped points merge; Flatten keeps open paths; the Actions palette gets tabs, ranked search, a keyboard highlight and recents; the colour picker opens on a new fill or stroke; text strokes follow their alignment; selection highlights after line breaks; a draggable pages/layers divider; variant properties reorder by drag; submenus keep their hover with a safe triangle; menu actions that need a value ask for it; File ▸ Rename edits the name in place. Engine: bad paint indexes, non-finite geometry and pages in copy/cut are refused; a param naming a layer says so when it isn't one; a CLI script is one undo step and resolves `$step`. Server and collaboration: message limits follow `max_file_mb` (client capped at 1 GiB); a damaged generation field no longer drops flushed edits; the web build joins a session from a `#join=` link. Also Swedish command labels, Nix CI through the shared workflow, paint bounds once per render, and a guard that turns a panic inside the boolean-op library into bad input (the stroke draws unclipped).
