M1: bound control connection transport waits
Fix #1726 with idle, absolute line and reply-write deadlines and connection-slot guards. Add real-loopback regressions and document reconnect behavior. Validated with cargo xtask ci: all seven gates passed; 6156 tests passed, zero failed, seven existing ignored.

|---|---|
|

| 2026-10-13 | Control sockets close after bounded idle, partial-line and reply-write waits, returning their connection slot (#1726); existing command processing timeout remains separate. |
|
||||
| 2026-10-13 | Image Trace: neighbouring colours share one fitted edge (gaps between them 22 to 50 px of area down to under 2), a 16 megapixel photo traces in 0.9 GB (was 3.9), stroked centre lines lie in the middle of their ink at its width (0.30 to 0.05 px off, 18 to 3 anchors a stroke), nearly level lines are levelled, more sharp corners are kept; new: Ignore Color, the Auto Color and Outline presets, and the Shapes, Auto Grouping and Gradients options (off by default) ([`docs/image-trace-quality.md`](docs/image-trace-quality.md)). |
|
||||
| 2026-10-13 | The interface is available in Polish (`pl`): menus, panels, dialogs and messages, with one/few/many plurals; AI-drafted, native review pending (#1498). Native documents with a lot of path data (traced or generated art, in layers, symbols or patterns) are saved as compact JSON, about a fifth of the size; small documents stay pretty-printed (#1492). Paste takes a PDF or EPS another app copied as editable vector art: from the macOS pasteboard (with SVG), EPS on Windows beside PDF, and `.eps` files copied in a file manager, with the new command `clipboard.importEps` (#1538, fixes #1499). Opening or placing a file with an image too large to decode says so, and the Links panel shows it on the row (#1540, part of #1479). Import: a multi-artboard `.ai` with notes beside its artboards opens from its editing data, a page's art past its artboard no longer lying over the page before it (#1528); a `.ai` gradient whose stops are listed upwards keeps each midpoint on the stop that starts its part of the ramp (#1530); SVG text on a path follows basic shapes (circle, ellipse, rect, line, polyline, polygon) as their SVG 2 equivalent paths (#1531, fixes #1527); PDFs whose alpha soft masks are drawn as images import with the mask instead of empty art (#1551); EPS and PostScript type set in Type 42 (TrueType) fonts imports at its size instead of 1000 times too large (#1553); PDF and EPS import keep a clipping path whose bounding box covers the page but whose shape doesn't (#1544, fixes #1542). Make Compound Path on a group (such as outlined type) keeps the paint of its backmost path instead of drawing nothing, and compound paths joined into one keep their holes (#1537). Live Corners: a round corner next to a curved side curves smoothly instead of sticking out of the shape, and the Smooth tool smooths only the stretch of path under the drag (#1547, fixes #1512). Join merges the selected anchor points that lie on one another, as after Average, into one anchor (#1582, fixes #1533). Guides: Lock Guides also locks the objects made into guides: they can't be selected, moved or deleted (#1543); they are drawn in the guide colour and style of Preferences, and a dragged selection snaps to ruler guides with Smart Guides on (#1583, fixes #1534). Edit › Keyboard Shortcuts lists Edit › Duplicate and the other commands that are in no menu but run without parameters (panel-menu commands such as Break Link to Symbol), so they can be given shortcuts (#1549, #1580, fixes #1539). Raster effects (blur, shadow, glow, grain) drawn after a pattern, radial or freeform gradient fill export at their place and size (#1541, fixes #1536). Fonts: the font scan on Linux also reads the folders fontconfig's configuration lists, such as TeX fonts under `/usr/share/texmf/fonts` (#1548, fixes #1529; not verified on Linux). |
|
||||
| 2026-10-13 | Image Trace's colour presets trace flat art with its own colours however many are asked for (noise no longer shatters it: 16 Colors 70 → 4 paths on the harness's flat art; no slivers of in-between colour along anti-aliased edges), and the photo presets trace a photo into smooth tones without specks or hairlines (High Fidelity Photo 3,653 → 121 paths, colour error 2.30 → 1.75; 16 megapixels traced where 4 were refused) ([`docs/image-trace-quality.md`](docs/image-trace-quality.md)). |

- [x] Release connection slots on worker exit, including timeout and failed worker creation.

- [x] Preserve correlated replies and persistent connections within the transport budgets.

| 2026-10-13 | minor | The interface is available in Polish (`pl`): menus, panels, dialogs and messages, with one/few/many plurals; AI-drafted, native review pending (#1498); Native documents with a lot of path data (traced or generated art, in layers, symbols or patterns) are saved as compact JSON, about a fifth of the size; small documents stay pretty-printed (#1492); Paste takes a PDF or EPS another app copied as editable vector art: from the macOS pasteboard (with SVG), EPS on Windows beside PDF, and `.eps` files copied in a file manager, with the new command `clipboard.importEps` (#1538, fixes #1499); Opening or placing a file with an image too large to decode says so, and the Links panel shows it on the row (#1540, part of #1479); a multi-artboard `.ai` with notes beside its artboards opens from its editing data, a page's art past its artboard no longer lying over the page before it (#1528); a `.ai` gradient whose stops are listed upwards keeps each midpoint on the stop that starts its part of the ramp (#1530); SVG text on a path follows basic shapes (circle, ellipse, rect, line, polyline, polygon) as their SVG 2 equivalent paths (#1531, fixes #1527); PDFs whose alpha soft masks are drawn as images import with the mask instead of empty art (#1551); EPS and PostScript type set in Type 42 (TrueType) fonts imports at its size instead of 1000 times too large (#1553); PDF and EPS import keep a clipping path whose bounding box covers the page but whose shape doesn't (#1544, fixes #1542); Make Compound Path on a group (such as outlined type) keeps the paint of its backmost path instead of drawing nothing, and compound paths joined into one keep their holes (#1537); a round corner next to a curved side curves smoothly instead of sticking out of the shape and the Smooth tool smooths only the stretch of path under the drag (#1547, fixes #1512); Join merges the selected anchor points that lie on one another, as after Average, into one anchor (#1582, fixes #1533); Lock Guides also locks the objects made into guides: they can't be selected, moved or deleted (#1543); they are drawn in the guide colour and style of Preferences, and a dragged selection snaps to ruler guides with Smart Guides on (#1583, fixes #1534); Edit › Keyboard Shortcuts lists Edit › Duplicate and the other commands that are in no menu but run without parameters (panel-menu commands such as Break Link to Symbol), so they can be given shortcuts (#1549, #1580, fixes #1539); Raster effects (blur, shadow, glow, grain) drawn after a pattern, radial or freeform gradient fill export at their place and size (#1541, fixes #1536); the font scan on Linux also reads the folders fontconfig's configuration lists, such as TeX fonts under `/usr/share/texmf/fonts` (#1548, fixes #1529; not verified on Linux); estimates unchanged |

| 2026-10-13 | minor | Direct Selection takes the selected object's anchor where anchors of overlapping objects coincide (#1508); commands and MCP `add_text` report area type that does not fit its frame (#1471), a tab stop in the Tabs panel drags from where the press landed (#1458); M9: 3D and Materials on outlined type and other shapes of many small curves (#1481), Twist 0° to 360° (#1524), twisted walls keep their faces (#1525); print-size images draw, export and crop (#1517), `vectorcraft-cli perf` reports load and memory on Windows (#1502); sliders in dialogs show their rail (#1483), a template layer stays in Preview in Outline view (#1486), French catalog complete again (#1511), a Hungarian message in the informal address (#1474); `graph.setData`'s CSV keeps each value exactly (#1485); estimates unchanged |
