Tests: `board_route_tests` (three). Numbers unchanged. |
 | 2026-10-31 | minor | M12: as the help describes, holding Cmd/Ctrl while moving a connector's end places it on any part of an object instead of snapping to a side. It keeps that spot as a fraction of the object's box, so it follows the object when it moves or resizes, and without the key an end snaps as before. `board.connector {fromAt, toAt}` and `board.reattach {at}` take it; saved only when set. Numbers unchanged |
 | 2026-10-31 | patch | M12, #1708: a connector end dropped on the outer half of a shape takes the side it is towards, instead of only within 10 px of a side's middle, so a drop anywhere along an edge chooses that edge (dragging a selected connector's end and with the connector tool, ring included); a drop in the middle of a shape still takes the facing side. |
 | 2026-10-31 | minor | M12, #1710: a selected elbow or curved connector shows path handles. Dragging a run moves it and a first or last run gains an extra run to stay on its end; a curve's middle goes where it is dragged (`board.reshape`, one undo step). The shape travels with what the connector joins, is saved with the file, and goes back to routing itself when the style changes or an end moves to something else. |

With `team_files = "edit"` (or `comment`, `view`) everyone who reaches the server sees the files shared from it now (a link of theirs has a join code: Share ▸ Start sharing) and joins them by a team list link, `figcraft://join?server=…&file=…&team=1`, which carries no secret: the server hands out the file's team link while it stays shared (`ResolveTeam`, answered like a join code), and Stop sharing revokes it with the others, disconnecting whoever joined with it. Turning the list off or changing its access refuses the old team links at once. `collab.files {refresh}` asks the server in Preferences for its list (`Admin::Team`; not the public server FigCraft ships with), and Home ▸ Online shows it below your own files: a row joins its file, its menu copies the link for the app or, with the server's `web_url`, for the browser build (`<web_url>#join=…`). A browser build served beside its server names it with `<meta name="figcraft-server">`, the page's default for sharing, codes and the team list.

+| 2026-11-06 | patch | M3: a glass's light angle bound to a number past ±180 turns round to the same direction (270 is -90), as the angle drawn from it does, instead of stopping at 180. Tests: `effects_tests::a_bound_light_angle_turns_round_instead_of_stopping`. Grade unchanged. |
+| 2026-11-06 | patch | M3: a layer's effect binding (`variable.bind`, `effects/<i>/<field>`) takes only a field its effect has, as an effect style's does: `effects/0/refraction` on a drop shadow, or a binding on an effect the layer doesn't have, is refused instead of being kept and doing nothing (a binding an older file has there still does nothing, and unbinds).

The file opens in a tab, or an open tab comes to the front, on the main's page with the main selected and zoomed to: a nested instance goes to its own main, a variant to that variant. A main deleted from the library file since it was published leaves the file open with a note; a library file that moved, a team library on a server and a path off this computer are refused with a message.

 | 2026-11-02 | minor | M3, #1885: glass effects take variables, as the reference tool's do: its light angle, intensity, refraction, depth, dispersion, frost and splay bind to number variables on a layer (`variable.bind`, `effects/<i>/<lightAngle\|lightIntensity\|refraction\|depth\|dispersion\|radius\|splay>`, `radius` being the frost) and in an effect style (`style.bind`), and the Design panel's glass fields take a variable like the shadow and blur fields. A variable reads as the field shows it: intensity, refraction, dispersion and splay in percent. Tests: `binding_lists_tests::glass_fields_take_number_variables`, `effects_tests::glass_fields_take_bound_numbers_as_the_panel_shows_them`. Grade unchanged. |
 | 2026-11-01 | patch | M3: Delete on a layer inside an instance hides it (an override) instead of being refused ("You can't delete a layer or object from an instance. If you try, Figma will only toggle the layer's visibility instead of removing it", Guide to auto layout); `edit.delete` reports those ids under `hidden`, the structure and the main component stay as they were, one undo step; deleting the instance itself still removes it. Found by a documentation audit of the auto layout page.

Four new UI strings (English only; other catalogs fall back). |
 | 2026-10-30 | minor | Bosnian (`bs`, Bosanski) draft catalog: every UI string (1,906), command label (629) and menu wording (31), machine-drafted in Latin script with ijekavian forms and marked as a draft awaiting native review. Bosnian plurals: one for 1, 21, 31… (not 11), few for 2–4, 22–24… (not 12–14), other for the rest. Grade and hours unchanged (Bosnian is not one of the twelve key languages) |
 | 2026-10-29 | minor | German terminology corrections (M10): gradient stops, OpenType stylistic sets and the Home-screen preference; partial review, catalog remains a draft. Nine existing translations corrected; keys, placeholders, coverage, grade and estimates unchanged |
 | 2026-10-28 | minor | Arabic draft: 1,857 UI entries, 620 command labels and 31 menu wordings, with count-neutral plurals. AI-assisted, native review pending. Desktop uses the existing Arabic fallback and bidi; web requires an embedded Arabic face. No panel mirroring or parity-grade increase claimed |
