 | Date | Change | Summary |
 |---|---|---|
+| 2026-10-30 | minor | M8, #1079: a `.figcraft` file unpacks at most 6 GiB in all when it opens (2 GiB in the browser), every area together, beyond each area's own cap; what passes it is left out with a note (images stay in the file, #1313). Numbers unchanged. |
 | 2026-10-30 | minor | M8, #1077: `.fig` import: instance expansion no longer walks variable nodes per instance or copies every outer override row into each nested instance; crafted files that took 14 s and 40 s import in 21 ms and 98 ms, normal files map as before. Numbers unchanged. |
 | 2026-10-30 | minor | M12, #1342: a FigJam `.jam` file opens as a board, our whiteboard file kind, instead of a design file: the `.fig` reader marks a canvas with FigJam's `fig-jam.` header as `FileKind::Board`, so the file opens with the board toolbar, the dot grid and the board panels, and saves as a board. A `.fig` stays a design file, and `file.import` of a `.jam` adds its pages to the open file without changing its kind. Its stickies and shapes with text are still frames with their generated layers and its connectors vectors, not native board objects. Tests: `board_import_tests.rs` (the kind, `.jam` against `.fig`), `jam_open_tests.rs` (open as a board, import into a design file). |
 | 2026-10-30 | minor | M6, #1342: FigJam `.jam` files open. A `.jam` is the same archive as a `.fig` (its canvas header reads `fig-jam.`), and the `.fig` reader already took it when a copy was renamed; now File ▸ Open, its file filter, drag and drop (home screen and canvas), `file.import` and the command line take `.jam` too, and the home screen's recent files show their thumbnails. What comes in is what the `.fig` reader makes of FigJam layers: stickies and shapes with text as frames with their generated layers, tables, stamps and the like as frames with an import note, connectors as vectors, and a layer type it doesn't know left out with a note naming it. The file opens as a design file, not a board, and its objects carry no board metadata yet. Tests: a synthetic `fig-jam.` canvas, bare and zipped (`board_import_tests.rs`), a `.jam` made from our own `.fig` export opened and imported (`jam_open_tests.rs`), the extension checks (`home_tests.rs`). |
