As Illustrator's help describes (Filter fonts by classification, Font Technology › Variable), the font menu gets a Font Technology row whose Variable choice lists only the families with variation axes, together with the script, kind, favourites and search filters, and stays set from one opening to the next. A family is variable when any of its faces, loaded or scanned, has an `fvar` table, so a family installed as static files beside a variable one counts.

COLR and SVG glyphs, which have no outlines, were left out wherever type was taken as its outlines: geometry effects, Expand Appearance, EMF/WMF export.
A root size without a viewBox sets up the em, a viewBox that isn't square is centred in it, and a glyph element nested in others is drawn on its own, as if used.
A PDF names fonts by PostScript name. When the font isn't installed at import, the importer
splits the name (`Honoka-Mincho` → family Honoka, style Mincho) and the document keeps that
pair. Installing the font later didn't help when its family name shares nothing with its
PostScript name (ほのか明朝): the pair stayed missing. FontDb::canonical now also looks the
pair up, joined, among the PostScript names, and answers with that face's own family and style.
The renderer placed symbol art that holds a blend, an envelope or a
repeat again for every instance in every frame. The live object in the
placed copy was a new node each time, and the renderer evaluated it
again. Symbol art that is itself a live object, an opacity mask whose
art is one, and a live object in a clip group in Outline view were
drawn from an uncached copy in every frame. At 1000 x 1000 pixels,
2,000 instances of a symbol holding an envelope took 126 ms a frame on
main, and the same 2,000 envelopes on the page took 30 ms.
The renderer now keeps the placed art of instances and inline graphics
when it holds blends, envelopes or repeats, and when the art is itself
a live object. It draws kept live art, opacity-mask art and Outline
view clip members that are live objects from the live cache, which
evaluates them again when the symbols, patterns, fonts or color
settings they show change. The 2,000 instances take 28 ms a frame,
with the same pixels.

Review follow-up (CodeRabbit, clean-room): the test header, gaps.md and
target-app-parity.md quoted a phrase from the cited help page. Comments
and docs only.
The Simplify help page says a path can be simplified whole or "a specific
path region with the Direct Selection tool"
(https://helpx.adobe.com/illustrator/desktop/draw-shapes-and-paths/modify-paths/manually-simplify-paths.html).
Simplify refitted every selected path whole, whatever part of it was
direct-selected.
object.path.simplify now looks at each path's direct selection: the
segments picked as segments, or else every segment with both anchors
selected. Each run of consecutive selected segments is refitted on its own
(vectorcraft_pathops::simplify_part) between its two end anchors, which stay
where they are with their handles on the side away from the run; every
other anchor and segment stays exactly as it was. A closed path's run may
cross its start point (the path then starts at the run's end anchor),
separate runs on one path simplify independently in one undo step, and the
runs stay direct-selected (as segments when segments were picked). A path
with only lone anchors selected still simplifies whole, as before, and
wholePaths: true simplifies partly selected paths whole. The slider, its
preview, Auto-Simplify and the Simplify dialog all run the command, so
they act on the part too. simplify_with now shares its run fitting with
the part refit (same results).
Verification: crates/engine/src/tests_simplify_part.rs (unselected anchors
and segments equal bit for bit, run end anchors fixed, the run within the
tolerance, two runs equal to each simplified alone in one undo step, a
closed run across the start point, picked segments, wholePaths, slider
preview and Auto-Simplify, a run that can't be simpler records no step)
and simplify_slider_and_dialog_simplify_only_the_direct_selected_part_of_a_path
(the slider's preview, Enter and the dialog's OK). Live: the release build's
slider at level 20 on a 91-anchor wave with anchors 30–60 selected refits
only that stretch.
A file opened or placed off the UI thread waited while the active tool
reported busy. The Dimension tool also reports busy between its clicks,
so after one click a ready file stayed queued with its spinner until
the dimension was finished or canceled. Files also waited between the
clicks of the Blend tool.
The session now records whether the pointer button is held. A file
waits for a busy tool only while the button is held. A file that
opens between a tool's clicks resets the tool, as a switch of
documents does; a file placed in the active document leaves the
tool's clicks in place. Files still wait while a dialog is open, a
drag is under way or a preview is open, and a tool's preview between
its clicks counts as one (the Flare tool after its center drag, the
Dimension tool's line once the pointer moves after its second click).
The drawing modes help page
(https://helpx.adobe.com/illustrator/desktop/draw-shapes-and-paths/learn-drawing-basics/drawing-modes-overview.html)
has you draw or paste into the selected object in Draw Inside. The isolation
help page
(https://helpx.adobe.com/illustrator/desktop/manage-objects/select-objects/isolate-objects.html)
isolates a path, group or object on a double-click with the Selection tool,
and puts art added in isolation mode where the isolated art was once the mode
ends, so that art belongs with what is isolated.
Steps: select a path, choose Draw Inside, double-click the path with the
Selection tool (it is isolated), then draw or paste. The art went into the
clip group Draw Inside makes around the path, but isolation mode stayed on the
bare path, so the new art was outside it: drawn dimmed, passed through by
clicks and marquees, and a double-click on it selected the path and never
entered the clip group. Double-clicking an existing Draw Inside clip group
from outside isolation mode already isolated it, and pastes then went inside
it; that is unchanged.
Cause: create::insert_look_turned and edit::paste_clip put the art into
create::draw_inside_group's clip group but left DocState::isolation on the
object drawn into, and with a single object isolated, hit testing reaches
only that object.
Change: when the object drawn into is the isolated one, isolation moves to its
clip group (create::isolate_draw_inside_group), after new art and after Draw
Inside pastes. A drag's previews replay from its snapshot and make the group
under the same id, and cancelling the drag restores the isolation it began
with. Undo and redo end isolation mode when the isolated object is no longer
in the document (the undone clip group), as mask editing already does,
instead of keeping an id a later object may take.
Verification: drawing_inside_an_isolated_object_keeps_the_new_art_in_isolation_mode
fails without the change (isolation Some(NodeId(2)) instead of the clip group
Some(NodeId(6))). A whole-window egui run through the control channel's
ui.click/ui.drag (double-click the rectangle, drag an ellipse inside, paste,
click the copy) left isolation on the rectangle and the click selected the
rectangle before; after, isolation is on the clip group and the click selects
the copy.
Converting a frame of threaded text to point type left the frame's
text in the point type, and the re-flow also added that text to the
story, as it does for a frame that was deleted. The other frames then
held it a second time.
A frame that is still in the document as point type now leaves its
thread with the text it holds. The story flows through the other
frames without that text, so each character is held once. A thread
left with one frame is no longer a thread, and undo restores the
thread.
