+| 2026-11-10 | minor | `.ai` and EPS import: an envelope of type, which keeps its drawn art with its type hidden, now says so in the import notes ("type in an envelope comes in as the envelope's drawn art, not as editable type"); nothing said it before, while the other envelopes that keep their drawn art have a note. The type is still not editable in the envelope (part of #3179). Test `tests_native::envelope_options_keep_the_source_text_hidden_under_its_outlined_appearance` |
 | 2026-11-10 | minor | `.ai` and EPS import: the check that keeps a live envelope or warped type only where it draws as the art saved with it renders each on its own, over nothing, and compared the pixels seen on white, where white art looks like nothing. White contents that drew somewhere else passed it and opened live in the wrong place (white warped type off its banner, in users' files). Pixels now also differ when they look different seen on black, so such art keeps its saved art, as colored art does.

 | 2026-11-10 | minor | PDF import: an image in a DeviceN space of one colorant opens as a Separation image does (#6314): a grayscale image of its tints colorized by its ink. One of two or more colorants that are all process plates (Cyan, Magenta, Yellow, Black, and the ink `None`) opens as a CMYK image, each colorant's tint in its plate and its Decode array applied (8 or 16 bits a sample; one that can't be read, such as a JPEG, opens in RGB with the CMYK images' warning). Both used to open as RGB images, losing their inks. A DeviceN image that mixes a spot ink with other colorants, such as a duotone, still opens as RGB: an image holds one ink or the process plates, not both (#6348). Tests `colorize::a_devicen_image_of_one_ink_opens_colorized_by_it`, `colorize::a_devicen_image_of_process_plates_opens_in_cmyk`, `colorize::a_duotone_devicen_image_still_opens_as_rgb` |
 | 2026-11-09 | minor | `.ai` import: an image whose color space `XC` sets to one ink (`n [c m y k /DeviceCMYK (name) /Separation] XC`, or an RGB alternate) opened as a gray RGB image: its samples, the ink's tints (255 at 100 %), were read as gray levels, so the tints drew inverted and the ink was lost. It now opens as a grayscale image of the tints, black at 100 %, colorized by the ink at 100 %: a spot swatch, a process plate's CMYK color (no swatch of its name), or Registration; the ink's color counts toward the document's color mode as a fill's does. Its alpha channel becomes its opacity mask, a reduced large image's too: a colorized image reduced to fit the limits (an image mask included) now keeps its alpha as an opacity mask rather than in its pixels, as at its full size. 8-bit and 1-bit samples, binary or in hex comment lines. A device space (`/DeviceGray XC` after a linked image's file name) and the ink `None` change nothing, as before; linked images (`XF`) keep their placeholder. Tests `import::ai::tests::separation_images_are_colorized_with_their_ink`, `separation_images_of_process_plates_and_registration`, `a_separation_image_with_hex_comment_lines_keeps_its_ink`, `a_reduced_separation_image_keeps_its_ink_and_its_alpha_as_a_mask` (#6350) |

The file still opens from its page or PDF part when no box can be found, when live art or another unread object shares the page art inside it, when the object spans two artboards or lies on an artboard that has no page, when no page art lies inside its box, when that page art is inside a page group with a clip, mask, transparency or appearance, when the object holds a frame of threaded type, when the page art uses a pattern, image or swatch that the page lacks or that differs from the editing data's, or when the page art doesn't carry the object's transparency (#4806; `crates/eps/src/import/tests_native.rs`, `crates/engine/src/cmd/fileio/tests_aiimport.rs`).

An envelope that can't be read, or that VectorCraft draws differently from the file's drawn art, keeps that drawn art, with a note.

     In a `.ai` opened from its editing data, Convert to Shape on a whole path or type object opens as a live Rectangle, Rounded Rectangle or Ellipse effect with its Absolute or Relative size, its corner radius, its place among the object's effects and whether it is hidden. A relative size in the file is added to each side. A relative Ellipse, or a setting VectorCraft doesn't read, keeps the drawn art (`crates/eps/src/import/ai/style/tests.rs`, `crates/eps/src/import/ai/tests.rs`, `crates/eps/src/import/tests_native.rs`).
     In a `.ai` opened from its editing data, Bas Relief in an art style takes its Detail, Smoothness and Light direction from the style's settings block, and an object other than type with it opens as itself with the live effect. A settings block that VectorCraft can't read (malformed, another effect's, a value out of range or a key it doesn't know) keeps the object's drawn look (part of #637; [raster effects reference](https://helpx.adobe.com/illustrator/desktop/special-effects-styles/apply-filter-effects/raster-effects-reference.html), [Photoshop File Formats Specification](https://www.adobe.com/devnet-apps/photoshop/fileformatashtml/), [scripting the filter gallery](https://community.adobe.com/questions-712/scripting-support-for-the-filter-gallery-1064646); `crates/eps/src/import/ai/style/tests.rs`, `crates/eps/src/import/ai/tests.rs`).
