 | Date | Change | Summary |
 |---|---|---|
+| 2026-11-01 | minor | G13: Artboard background colors in output (#4937): raster exports (a transparent background too), PDF, SVG and EPS pages, `.ai` files' PDF pages, Export for Screens and print (and its preview) draw each artboard's color behind its art, inside the artboard and in the color's own model; Export for Screens has Include Artboard Fill beside Include Bleed (on by default, remembered; `includeArtboardFill`, also on `document.export` and `file.print`); editing data keeps the color as the artboard's, and Export for Screens' document rows keep it too; estimate unchanged. |
 | 2026-11-01 | minor | G5: Select › Start Global Edit on a group takes the groups like it (the same objects at the same places, moved or scaled; Appearance, Size and the artboard options apply) and gives an edit made to an object inside one to the object at its place in each of the others, in proportion, as one undo step (#4939); rotated copies and Shift-click exclusion remain. Estimate unchanged. |
 | 2026-10-31 | minor | G4: PDF import finds an installed font whose PDF name holds hyphens (`Noto-Sans-Bold` is Noto Sans, Bold: the longest part before a hyphen that names an installed family) and a composite font by its CIDFont's name rather than its base name, which ends in the CMap's (`Name-Identity-H`, [ISO 32000-1 §9.7.6.1](https://opensource.adobe.com/dc-acrobat-sdk-docs/pdfstandards/PDF32000_2008.pdf)); a missing font is split only before a style part (`Helvetica-BoldOblique`), so it is reported as `MS PGothic`, not `MS`. Estimate unchanged. |
 | 2026-10-31 | minor | G13: Direct Selection snaps the end of an existing straight line, dragged by its end anchor, square to straight paths and grazing curves (Smart Guides › Geometric Guides: Snap to Perpendicular and Snap to Tangent), the case the public Snap to Perpendicular and Snap to Tangent pages add to drawing with the Line Segment and Pen tools (#2530). Scores and estimates unchanged. |
