v0.9.1

GPUI Kit v0.9.1

GPUI Kit 0.9.1 is a backward-compatible patch release. It adds a draggable GridLayout, right-pinned table columns, Markdown task checkboxes, link tooltips and motion transitions that outlive their element, along with a large batch of input, text, slider, accessibility and gpui-shell hardening fixes. The default backend moves to gpui-pre 0.3.12 and the optional GPUI Fast backend to 0.1.14.

New APIs

• GridLayout: a grid whose items the user drags and resizes, also registered in the gpui-shell component catalog. (#3770, #3789)
• Table: ColumnFixed::Right pins columns to the right edge. (#3833)
• Text: on_task_toggle makes Markdown task checkboxes clickable; block surfaces in TextView; pointer-following link tooltips. (#3811, #3830, #3793)
• Motion: TransitionState for transitions that outlive their element. (#3841)
• Components: Button::selected_accent, Slider::track_focus, Dialog::accessibility_label, TimeField::separator, Toolbar::axis for vertical toolbars, and a ratio-sized PieChart hole. (#3775, #3824, #3826, #3829, #3821, #3784)
• WindowBorder: the frame colour comes from the window.border theme token, and window corners can be rounded on request. (#3849, #3848)

Editor and text input

• Keep the first typed character in the editor search panel, compose decoration styles deterministically, draw a placeholder for a folded line, and show the arrow over the gutter. (#3772, #3777, #3791, #3806)
• Tell the platform when the caret moves, publish layout at the end of prepaint, notify a moved input only while focused, and wait for the first layout before shaping an early value. (#3827, #3831, #3828, #3864)
• Keep the caret's visual line at soft wraps. (#3842)

Markdown and text rendering

• Supply editor foreground ranges through the render context and give span-less HTML paragraphs unique ids. (#3754, #3771)
• Tables: highlight the hovered body row, select aligned cell text where it is drawn, and size columns to their images. (#3812, #3813, #3787)
• Limit selection highlights to selected glyphs, draw unsized inline images at their own size, and avoid quadratic paragraph highlight merging. (#3799, #3786, #3846)

Components

• Table / DataTable: name rows after their cells, centre default header names, Tab and Shift+Tab leave a focused DataTable, and a selected cell gets a border distinct from hover. (#3773, #3731, #3800, #3866)
• Slider: allow min above the default max while building, snap dragged values to steps from min, and step one thumb from assistive technology. (#3823, #3822, #3840)
• Menu: size items and default max width in rems, and open a scrollable menu on its checked item. (#3809, #3814)
• Settings: follow locale changes in the search placeholder, clear search on Escape, show an empty state for unmatched searches. (#3815, #3816, #3692)
• Motion: reverse an interrupted transition as CSS does, and keep value-transition timing under reduced motion. (#3820, #3839)
• Scrolling: stop smooth-scrolling wheels at the edge on macOS, let the parent scroll a swipe over a fitting horizontal area, and keep the overscroll stream alive through sideways packets. (#3781, #3779, #3790)
• List, Tab, WindowBorder: accent rows use accent_foreground, icon-only tabs keep their width, the element id path stays stable across decoration changes. (#3774, #3792, #3783)
• Diff: reject invalid hunk prefixes before slicing UTF-8. (#3473)
• WebView: fix an X11 abort when a WebView is dropped on Linux. (#3862)

Accessibility

• Report a disabled SliderThumb to assistive technology. (#3825)

gpui-shell security and robustness

• Require a network grant for WebViewState pages, accept only "*" as the unrestricted execute grant, and check Link.href against the URL scheme rule. (#3782, #3802, #3804)
• Refuse bundle values that would break generated scripts, bound script-supplied counts, nesting depth and self-nesting views, and leave proxy URLs out of the default process.env. (#3803, #3805, #3808, #3817, #3810)
• Stop a Git dependency selector being read as a git fetch option, honor the manifest entry when bundling, expose group hover to scripts, and shrink materialize_node frames. (#3778, #3682, #3796, #3807)

Dependencies

• Update rustls-webpki and webpki-root-certs for CVE-2026-111943. (#3801)
• gpui-pre 0.3.12 and gpui-fast 0.1.14. Under GPUI Fast 0.1.14, views that were not notified reuse the previous frame instead of rebuilding. (#3867)
