 | 2026-11-03 | minor | M12, #1919: as the quick create help says ("Click to select and create the next shape in that direction, or drag the preview to any location on your board"; "A new shape is created with a connector and its text field active"), a "+" beside the selected sticky or shape can be dragged: the preview follows the pointer and, let go on empty board, the next one is made there, centred on the pointer, and joined by a connector leaving by the handle's side and arriving by the side facing it (`board.addConnected` gains `at: [x, y]`, a point of the page placed in the parent's coordinates); let go on another sticky or shape, inside a section or frame too (`board::sticky_or_shape_at`), a connector joins the two instead (`board.connector`), that object outlined while the pointer is over it; let go off the canvas or over the toolbar, nothing, and the bar above the selection stays away meanwhile, as for any drag. The click is as before. A shape picker on drop and choosing the connector type are not done (the help doesn't describe them). Tests: `board_connect_tests` (the drag ones), engine `board_connected_tests::the_next_one_goes_where_it_is_dropped`. Numbers unchanged. |
 | 2026-11-04 | minor | M12, #1916: a connector end attached to a side starts 4 pt outside the border (`board_route::END_GAP`), as FigJam's do (the issue's screenshots: the line starts a few pixels outside, with a round cap), so the stroke never lies on the fill; elbows leaving one side share their first run along its normal, curves leave tangent to it and straight ones fan out from the same point; the `.jam` importer's routes, re-attached ends, path handles and labels follow the route's points; an end placed by hand with Cmd/Ctrl held keeps its exact point. Tests: `board_route_tests` (three). Numbers unchanged. |
+| 2026-11-04 | patch | M6, #1910: a `.jam` elbowed connector saved with its path (FigJam's `connectorControlPoints`) keeps it on import: the points become the `ConnectorPath::Runs` a connector reshaped by hand has and the line is walked along them, so a connector drawn around a layer stays around it; one whose points don't make a path from its ends' sides is routed as before. Still a vector, not a native board object. Details in [`file-format-parity.md`](file-format-parity.md). |
 | 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. |
