detail and milestones in [`docs/roadmap.md`](docs/roadmap.md). | Date | Change | Summary | |---|---|---| +| 2026-10-30 | minor | M9, #1130: the server key is compared by its hash. `Store::manage` hashes the presented and the kept key with SHA-256 and compares the two digests; the key on disk, `figcraft-server key` and rotation are unchanged. Regression tests in `store_tests` (`operator_key_*`). Numbers unchanged | | 2026-10-30 | minor | M8, #1082 (the rest): the SVG and PDF exporters drew a pattern fill's source from depth 0 again, and the renders they embed (a layer with effects drawn alone, a pattern cell with effects) started at 0 too, so an export could nest its own levels, the renderer's and a pattern's on top of each other. A pattern source now exports one level below the layer it fills, and what the renderer draws for a layer goes on from that layer's depth (`figcraft_render::at_layer_depth`), so one cap bounds the whole export; the render of what lies beneath a layer (background blur, glass) is of the page's own layers and still counts from the page. Canvas masks, mask content and boolean and outline walks already carried the depth or have their own small caps. Numbers unchanged. Tests: `render_depth_tests`, `figcraft-svg` and `figcraft-pdf` `pattern_depth_tests`. | | 2026-10-30 | minor | M8, #1082: a pattern fill drew its source as a fresh render from depth 0, so patterns in patterns could stack three renders of 256 levels; its source now goes on from the depth of the layer it fills, and the one cap bounds the whole render. Measured, a level takes about 6.5 KB of stack in a render (6.8 KB in a debug build), so the deepest allowed render needs about 1.7 MB: the canvas render threads, the save thread (it renders the thumbnail) and a band pool of their own now get 8 MiB stacks, like the desktop app's main thread (rayon's and other threads' default is 2 MiB). Numbers unchanged. Tests: `render_depth_tests` (the cap reached through a pattern; three 250-level chains of patterns in patterns rendered on a render thread's stack). | | 2026-10-30 | minor | M8, #1114 (explicit variables files only): sibling variables files were read with a 256 MiB cap and a regular-file check, but an explicit path given to `variable.import`, or as the `variables` of `file.open` and `file.import`, was read whole with no limit. That path now goes through the same capped read: an oversized file, a folder or a device fails with "not a file of at most 268435456 bytes" and the document, tabs and recent files stay as they were. The check reads the file's size before reading it, so a file that grows or is replaced in between is not bounded; primary document reads and `image.place` are left for the rest of #1114. Tests: `import_export_tests::an_explicit_variables_path_is_capped_like_the_sibling_file`, `variables_io_tests::variables_import_caps_the_file_it_reads`.

the key file, `figcraft-server key` and rotation are unchanged. Numbers unchanged. | | 2026-10-30 | minor | M8, #1074: `figcraft-server` keeps a file everyone left loaded for a minute (at most 16 files, 256 MiB together), so rejoining it reads nothing, and writes a file's open time at most hourly (and when it stops) instead of at every join and leave: join/leave cycles of an unchanged file do no disk I/O on the hub thread. Edits are saved as before. Numbers unchanged. | | 2026-10-30 | minor | M9, #1415 (the rest): `comment.people` lists names that were only @mentioned, and `comment.next` and `comment.prompt` carry each thread's mentions as `comment.list` does. Numbers unchanged. | | 2026-10-30 | minor | M9, #1525: share links can comment. A third access level, `comment`, sits between `edit` and `view`: someone who joins with a comment link (or its join code) sees the file live, as with a view link, and adds comment threads, replies, reactions and resolves them; any other edit is refused, by their app and by the server, which accepts a comment link's batch only when every change in it touches comment threads. Sharing online makes a comment link and code beside the edit and view ones, and the Share popover offers Can edit, Can comment and Can view; the toolbar shows a "Can comment" badge with Move, Hand and Comment. `collab.share {access: "comment"}`, `collab.manageFile {action: createLink, access: "comment"}` and `figcraft-server links create FILE --access comment` make and pick it. Older apps are unaffected: one that joins with a comment link is welcomed as a viewer, links listed to it read as view links, and a level an app doesn't know reads as view; an older server makes no comment link and sharing goes on without one. Comment authorship is the name in Preferences, as before (no accounts), so a commenter can edit or remove other people's threads. Tests: `comment_access_tests.rs` (collab), `comment_link_tests.rs` (engine, server end to end), the Share popover and toolbar in `live_share_tests.rs` and `live_server_tests.rs`. | diff --git a/docs/roadmap.md b/docs/roadmap.md index 889eccb07..97cd0e4c8 100644 --- a/docs/roadmap.md +++ b/docs/roadmap.md @@ -1,6 +1,6 @@ # FigCraft roadmap: milestones and what's next -> **Last reviewed:** 2026-10-10 · **Last updated:** 2026-10-30 · **Change:** minor (SVG and PDF exports count pattern sources and the renders they embed from the layer's depth, so one cap bounds a whole export (#1082);
