stops and stop flattened the path twice, once for the points and once
for its length, and stop did both before rejecting an index past the
last object. place validated the path with attachable_path first, and
transform measured the old and new paths up to three times each.
A private Measured value now holds the flattened first subpath with its
length and closed flag, and path_length, stops, stop and transform use
it. stop returns None for an out-of-range index without measuring, and
a move of the group measures no path.
attachable_path now uses path_length, so a path whose length overflows
to infinity is no longer offered as one objects can attach to when
placement cannot measure it.
A Smooth drag along the middle of a curved segment smoothed nothing when
neither of the segment's anchors was within the reach, and paths of two
anchors were never smoothed.
- path.smoothRegion searches each curved segment where it can come
within the reach, halving it down to pieces no longer than half the
reach, and adds an anchor in the middle of each stretch in reach; the
existing reach split then cuts the segment where the drag enters and
leaves the reach. A drag that only grazes a curve finds the place on
it nearest the drag. The search is bounded per drag and shared
equally by the segments in reach.
- Paths of two anchors are smoothed, open or closed.
- Alt with the Paintbrush smooths a selected two-anchor curve; a
two-anchor straight line still gets the closed stroke. Both sides use
one segment_is_straight test.
Part of #2224
- The clipping path of a clip group or a clipped layer takes no part,
the members of a compound clipping path included. Before, only a
plain clipping path was left out.
- In isolation mode only paths inside the isolated object are trimmed;
paths outside it still count as crossing.
- A rectangle or line that reaches so many paths that comparing their
boxes would take more than 50,000,000 tests is refused before any
work starts.
- A tool drag that goes 3 screen pixels or more from the press stays a
rectangle or line when it ends near the press. Before, it ran as a
click and could remove a whole path the final rectangle did not
touch.
Docs: docs/mcp.md.
The current File formats rows of docs/target-app-parity.md now name the legacy .ai manual kerning, discretionary hyphen and hyphenation language reading and writing, with their tests. Score, gaps and hours are unchanged.
While the Smooth tool drags with a path selected that it can smooth, a
dashed outline shows the band its release smooths: every point within
the tool's radius (12 screen pixels) of the drag, round at both ends.
Alt smoothing with the Pencil, Paintbrush and Blob Brush shows the same
band. A selection with no path the tool can change shows none.
- The band is kept in squares eight radii wide, and each step of the
drag adds its area only to the squares it reaches. A piece of a
square's outline along a side is left out only where the square
across holds band area.
- A drag segment too long for the squares (a jump drawn zoomed out and
viewed zoomed in) keeps its band near each end in the squares and
shows the rest as the two sides of its band. A step that cannot be
added whole is added one segment at a time.
- A coarser grid of cells lists the squares and long segments, so a new
one is checked only against those near it, and an outline is made
again only where the band near it changed.
- After a zoom change mid-drag the band is outlined again a few hundred
points per frame, and the work on long segments stops for the frame
after a fixed budget. Tools report unfinished overlays with
Tool::overlays_pending, and the canvas then draws again on the next
frame, so the band covers the whole drag even while the pointer holds
still.
A threaded story measured each type-on-a-path frame, and each area frame
whose lines align to the center, the bottom or justify vertically, with
the whole rest of the story. A story of 1,500 one-line paragraphs through
40 such frames was laid out over about 2.1 million bytes while the frames
were measured.
- Area type without Shrink Text to Fit now takes the paragraph probe for
every vertical alignment. A reflow pass that places less text is
undone, so when the final layout stops before the last paragraph break
measured, every pass placed the same lines as with the whole rest.
- Type on a path takes it when its line starts at the start bracket: no
Dynamic Text, Optical Margin Alignment or Roman Hanging Punctuation,
the first paragraph aligned Left, Justify Left or Auto, and vertical
type or no right-to-left text in the rest of the story. The story is
scanned for right-to-left text once per distribution.
- Shrink Text to Fit, the other path settings and a share that ends in
the story's last paragraph are still measured with the whole rest.
The same 40 frames are now measured over 21,035 bytes (aligned to the
center) and 20,583 bytes (paths aligned Left). Each frame's share is
unchanged: the tests compare every slice with the whole-rest result for
both distribution entry points, across alignments, frame shapes, wraps,
path settings, right-to-left text, styles, lists and seeded stories.
The Hindi catalog called a variable चर, परिवर्तनीय, वैरिएबल or
वेरिएबल from one row to the next: the Variables panel, Load and Save
Variable Library, Variable Options and the data-merge messages mixed
them, and so did variable widths, the font technology label and
environment variables. Every such row now says वेरिएबल (plural
वेरिएबल्स).
Close or Join, Join Point Text, Join the lines of each paragraph and
most of the path join messages said शामिल हों, which means joining a
group; the other join messages used जुड़ना, जॉइन or the English word.
They now say जोड़ें, as the Join command already did. The Discord rows
keep शामिल हों, and the stroke corner names and the Join tool keep
जॉइन.
hindi_rows_use_one_term_for_a_variable_and_for_joining_paths checks
both terms in every row. docs/localization-hi.md lists the terms, and
the Hindi row counts in it and in docs/localization-parity.md are
current (8,782 rows, 3,014 @msg).
Global Edit does not take images or text, so a group holding type or an
image is not a missing case. docs/gaps.md drops it from G5's Missing
line and states the exclusion next to the similar-groups entry, with
the help page. docs/ui-parity.md states the same exclusion and no longer
lists highlighting the matches before the start as remaining, since it
ships with a regression test. docs/target-app-parity.md gains an
Evidence line.
Closing a modified tab that is not in front shows it while the Save
Changes dialog asks about it. After Save or Don't Save, the closed tab's
neighbor became the current document instead of the document that was in
front before the question.
Closing a background tab with its close button, or `file.close` with its
`index`, now remembers the uid of the document in front in the dialog's
protected `__front` field, and once the asked document closes, that
document is made current again while it is still open. The field
survives a Save dialog shown off the UI thread. Cancel keeps the asked
document in front, closing the document in front still brings its
neighbor forward, and Close All and Quit are unchanged.
Type with an inline graphic was resolved only in the layers, so type in
the art of another symbol, a graph design, a pattern tile or an opacity
mask kept the size its graphic had when it was made. The symbol holding
that type, its instances and the inline graphics that show it were
measured from the stale layout.
- Inline graphics are resolved in every tree that holds type. Symbols
are resolved in dependency order, so a symbol's type is laid out
before the type that shows that symbol inline. Edits, opening,
reverting and Refresh Font List use the same pass.
- The pass visits each object once: it resolves the children first and
copies a node only when something below it changed. It measures each
symbol's art once per pass.
- An inline graphic of a symbol whose art shows that symbol inline,
directly or through other symbols, is an empty slot. The symbols on
such a cycle are found once and cached until the symbols change.
- A changed inline graphic also clears the text's cached baselines.
With Enable Touch Gestures on, a two-finger tap on the canvas undid and a
three-finger tap redid even while a modal dialog was open, and in the Touch
workspace a two-finger tap switched modes behind it. Fingers already down
when a dialog opened could still complete a tap when they lifted, during
the dialog or after it closed.
While a modal is open, from the frame it opens:
- no finger tap runs a command and no multi-finger gesture begins; the
fingers already down are forgotten, so lifting them later runs nothing
- a primary press does not reach the tool, a middle-button press does not
start a pan, and a double-click does nothing
- a long touch does not drop the canvas press
- a click in Presentation Mode does not step to the next artboard
- a pinch, wheel turn or trackpad rotation does not move the view, and the
rest of a wheel turn made under the dialog is dropped after it closes;
a new wheel turn after the dialog closes moves the view at once

Legacy .ai type (version 7) now reads the operators it used to skip:
- `autoKern kernValue Tk` (and `TK` in overflow text) sets the manual
kerning of the character before the pair, or at the start of a line
the space before the line's first character; autoKern 1 sets the
pair back to automatic. Values are kept to -1000..10000.
- `T+` and `T-` (discretionary hyphens) become soft hyphens.
- `languageID XL` sets the characters' language (ids 0 to 11).
- A visible text object read while a line breaking value (`TG`) or
Japanese layout rules (`Xu`, `Tu`) are set opens with a warning,
once per file for each.
Final-form positions (Tc, Tw, Tm, Td, T*, TR) stay ignored.
Legacy .ai saves now write manual kerning as `0 value Tk` after each
character that has it and before a paragraph's first character with
space before it, and soft hyphens as `T+`; manual kerning is no longer
listed among the attributes left out. The writer's prolog defines Tk
and T+.

The UI chrome rows in target-app-parity.md listed SVG Interactivity and
context menus beyond the canvas as remaining work. The SVG Interactivity
panel ships, and the canvas, Layers rows, artboard rows, libraries,
rulers and toolbar grips have menus, so the rows now name context menus
in the panels that have none. ui-parity.md drops a second checklist row
that listed SVG Interactivity as missing; the row above it already
lists Retype, Comments and Version History.
The gap lists and area tables said Layers rows, panels and type have
no context menu. Layer, sublayer, group and object rows offer Collect
for Export for the row or every highlighted row, and right-clicking
type opens the canvas menu. The docs now list what ships and name the
remaining gaps: other row menu commands, guide and blend spine rows,
and panels without a menu. The Layers panel menu list adds Collect for
Export, and SVG Interactivity leaves the missing list.
docs/target-app-parity.md listed the "Preferences that act" bullet three
times. Two older copies disagreed on Highlight Alternate Glyphs (one said
on by default, the code sets it off in Prefs::default) and still counted
about 14 stored options. The newest copy is kept, now with the Highlight
Alternate Glyphs clause (off by default), and its count names the two
options still stored only: Scratch Disks and the legacy vector clipboard.
The older of the two "Preferences audit (2026-10-30)" bullets, which still
listed five stored-only options, is removed, and the UI chrome summary row
now says 2 options, matching docs/gaps.md G12.
Brushes, Spot Color Objects, Pattern Objects and Gradient Objects left
out a fill or stroke that was hidden or at an opacity of 0, but still
listed an object that was itself hidden or at an opacity of 0, and the
objects inside such a group or layer. They now leave those out, their
characters' paints and colorized images included. With Selection Only,
an object selected inside a hidden group or layer, or one at an
opacity of 0, is left out too. Objects still counts every object.
While the Type tool edits text, holding Space no longer lends the Hand
tool or, with Shift, the Rotate View tool: the canvas does not show the
hand or rotate cursor, and a drag with Space held does not pan or turn
the view. Cmd+Space still lends the Zoom tool. The default keyboard
shortcuts help page lists the Spacebar as the Hand tool when not in
text-edit mode.
Test: canvas::tests::space_types_a_space_while_editing_text_and_does_not_pan
Edit > Edit Colors > Convert to Indexed Color... (edit.colors.toIndexed)
stores the embedded images in the selection as indexed-color PNGs: a
palette of at most 256 RGB colors, each pixel the index of one. The
dialog previews live and OK is one undo step.
- The palette is chosen as for a PNG-8 export (selective, perceptual,
adaptive, web, gray, black and white), as evenly spaced levels of red,
green and blue (uniform), or from the document's swatches. Dithering
is diffusion, pattern, noise or none, with an amount.
- Pixels under half opacity become one transparent entry; the others
become opaque in their own color. Linked images, colorized images and
color glyph images keep their pixels.
- An image that is already an indexed PNG and would show the same pixels
is left as it is, and no undo step is recorded when no image changes.
- An image of more than 134,217,728 pixels (33,554,432 in the web app)
is refused, read from its header before decoding.
- With Select All, locked and hidden objects that hold an image that is
not an indexed PNG yet are counted in notChanged, without converting
them.
- The quantizer gains quantize_to, which maps pixels to a given palette.

file.newProfiles.edit and file.newProfiles.reset returned the automation
access check and file system errors with the profile file's whole path,
so a client confined to read roots that leave out the preferences folder
learned where the folder is. The errors now go through naming_in_error,
like other paths the client did not give: whole inside the read roots,
otherwise by file name. docs/mcp.md and the params text say so.
The graph compares the paints a command leaves on it with the paints it
stored before the command, not with the value before each mark's
capture. Apply Fill to Stroke on two marks whose strokes already had
their fills stored the back mark's stroke and then the front mark's
again, and recorded an undo step with nothing changed. The same
comparison applies to the opacity and blend mode a series keeps.
docs/mcp.md states that only the topmost visible row's paint is stored,
and the Graphs line of docs/target-app-parity.md states that a series
that draws Filled Lines bands keeps no stroke paint or weight.
A document or brush library file could hold two brushes of one name.
Renaming the first in Brush Options moved every stroke of that name and
left the second brush unreachable, deleting by name removed both, and
the Brushes panel could not select the second row.
Reading a stored brush library now keeps the first brush of a name as
stored and numbers each later one with the first "Name 2", "Name 3" and
so on that the file does not already have. Strokes name their brush,
and a name always found the first brush, so every stroke keeps drawing
the brush it drew before. The rule applies to opened documents and to
brush library files; brushes added to a document that already has the
name keep today's numbering.
Docs: docs/mcp.md, docs/target-app-parity.md.
An envelope around type of only spaces and a rectangle mapped from the
union of the rectangle and the type's laid-out box, so the empty type
moved and scaled how the rectangle was distorted. Type that draws
nothing now adds no box while other content in the envelope has one,
in groups and layers and as a clipping path too. When nothing else in
the envelope has a box, the type keeps its laid-out box, so an envelope
of only empty type keeps its frame, Make with Mesh and Reset with Mesh
still work, and Release still gives back the warp shape.
This applies to Make with Warp, Make with Mesh, Make with Top Object,
Reset with Mesh, Edit Contents and the stroke margins. Type that has
not been measured yet keeps its laid-out box as before.
The PDF/.ai import's boxes for envelopes with Distort Appearance
measure each object as the whole contents measure it, so the margins
the import tries match the contents' geometric box. The three import
tests that measure type without registering the glyph measure now
register it first, so another test registering it while they run no
longer changes their result.
With automation read roots in force, svgInteractivity.info and the files
reply of addFile and removeFile returned every linked JavaScript file as
stored, including paths outside the roots. They now name such a file by
its file name alone, as document.json does; a file inside the roots and
a URL are named as they are, and the document keeps every path.
removeFile also unlinks a file outside the roots by that file name. When
the name fits more than one linked file, it returns an error that names
no stored path and unlinks nothing. addFile still treats only the same
text as already linked.
In a frame a request drives, the JavaScript Files dialog lists such a
file by its file name while its selection keeps the file as linked, and
ui.inspect gives the selected file the same way. The person's frames
show full paths.
