Added Badge dot styling as a new variant for indicators that need a subtle visual cue. Updated badge docs and demo examples to reflect the new badge variant and dot-style behavior.

Update Base UI to 1.5.0.

Fix InputGroup focus ring thickness and color: container mode uses 1.5px ring (wraps entire group including buttons), hybrid container zone and individual mode use 1px ring (thin to avoid colliding with adjacent buttons), and all modes use ring-kumo-focus/50 (50% opacity) to match the standalone Input component.

Fix error state red border on Combobox, Select, Autocomplete, and SensitiveInput to match Input behavior

Add inline label layout and fix auto-assigned node colors in tooltips

Fix Tooltip popup overflowing viewport when content is wider than available space. The popup now constrains its width to var(--available-width), a CSS variable provided by Base UI's Positioner that reflects the space between the trigger and the viewport edge.

Fix language alias normalization in ShikiProvider

• Add normalizeLanguage() function that maps common language aliases (js, ts, sh, yml, py, md, gql) to their canonical SupportedLanguage names
• Normalize language aliases in ShikiProvider when preloading grammars, so passing ['js', 'ts'] works the same as ['javascript', 'typescript']
• Normalize language aliases in highlight() hook at runtime, so code fences using js or ts highlight correctly without warnings
• Export normalizeLanguage from @cloudflare/kumo/code for consumers who need to normalize aliases themselves
• Intentionally omit mdx alias since MDX has a distinct grammar that would lose JSX highlighting if mapped to markdown

fix(banner): remove variant selection background for legibility

Selected text inside Banner now uses the browser default selection color instead of a same-hue variant-tinted background. The previous selection:bg-kumo-{info,warning,danger} utilities produced low contrast between the selection background and the variant text color (most notably in light mode for the error and alert variants), making selected text hard to read.

Add left and right props to SankeyChart for controlling series layout padding

Fix tooltip popup exit transitions by animating the Tailwind scale property alongside opacity.

Add passwordManagerIgnore to Input for suppressing password manager overlays on non-credential fields.

Add scroll fade to segmented tabs. When tabs overflow, gradient masks appear on the edges based on scroll position via scroll-driven animations (Chrome 115+, degrades gracefully). Scrollbar is hidden; the fade is the scroll affordance.

Add size="sm" variant to Tabs component (h-6.5 / 26px, matching Input sm)

Forward toastManager prop on <Toasty> so code outside the React tree (timers, query-cache listeners, module-load callbacks) can dispatch toasts via a manager created by createKumoToastManager(). Also surface createKumoToastManager on the top-level package export (previously only available via the deep @cloudflare/kumo/components/toast path).

Add transparent background to SankeyChart component

Expose optionUpdateBehavior prop on TimeseriesChart to control how ECharts applies option updates

Add hideLabel prop to Field so components can skip the native <label> while keeping description/error wiring. Use it in Select with Base UI's Select.Label to fix hover/focus coupling between the label text and trigger.

fix(input): render error and description props without requiring a label

fix(radio): prevent radio button distortion with long labels by adding shrink-0 to the default appearance radio indicator

Fix overflowing segmented Tabs drag-to-scroll interactions so mouse and touch drags reliably scroll while normal tab clicks still activate tabs.

Create Sankey Chart component

Fix CommandPalette List bottom ring being clipped by Footer background. Add scroll padding to prevent items from clipping behind rounded corners.

Deprecate to prop on Link in favor of href. The to prop is a routing-framework concept that doesn't belong on a presentational component. Use href for all link destinations and configure a LinkProvider wrapper to bridge to your router. to continues to work but emits a dev-mode deprecation warning.

Allow LayerCard.Primary and LayerCard.Secondary to accept all standard HTML div attributes, including data-testid for testing.

Set cursor-default on Tooltip triggers so disclosure buttons don't appear clickable. Overridable via className.

Export Combobox.Trigger, Combobox.Value, and Combobox.Icon — the raw Base UI primitives for building custom combobox triggers. Use these when you need full control over the trigger's visual treatment (e.g. a sidebar account switcher that renders as a plain button instead of an input-like control).

fix(CloudflareLogo): remove registered trademark symbol from full logo variant

Fix Google Translate DOM mutation crash in Button

Remove z-50 from mobile Sidebar Dialog backdrop and panel. The z-50 caused portaled floating elements (Popover, DropdownMenu, Select, Combobox) opened from inside the Sidebar to render behind the Dialog backdrop. Matches the pattern used by Kumo's own Dialog component, which relies on DOM order for stacking with no explicit z-index. Also adds data-sidebar-backdrop and data-sidebar-popup attributes as stable CSS hooks.

fix(combobox): forward all props from TriggerValue to ComboboxBase.Value, enabling placeholder support and styled placeholder text via data-[placeholder]:text-kumo-placeholder

fix(registry): correct Select component metadata for AI-generated code

The component registry metadata was incorrectly typing Select's value, defaultValue, and onValueChange props as string, causing AI agents to produce broken code when implementing Select with object values (e.g., rendering object.value in the trigger instead of the label).

Changes:

• value type: string → T (generic, matches actual component interface)
• defaultValue type: string → T
• onValueChange type: (value: string) => void → (value: T) => void
• Added missing renderValue prop: (value: T) => ReactNode — required for object values
• Added missing items prop: supports both Record<string, string> and Array<{ label, value }> forms
• Added missing isItemEqualToValue prop: required for object equality comparison

Gracefully fall back to default variant instead of crashing when an invalid variant prop is passed at runtime. Previously 22 of 25 components would throw TypeError on unknown variant values; all 25 now use a shared resolveVariant() utility that returns the default config and logs a dev warning.

Forward all Base UI Panel props (including keepMounted and hiddenUntilFound) through Collapsible.DefaultPanel. Previously these were silently dropped because DefaultPanel used a standalone props interface instead of extending BasePanelProps.

Fix registry codegen to match demo examples when component export name differs from directory name (e.g. DropdownMenu vs dropdown). This restores missing examples for DropdownMenu and other affected components.

TooltipProvider props (delay, closeDelay, timeout) are now shown in the Tooltip component's API Reference on the docs site.

Rebalanced semantic text token usage to improve hierarchy and consistency across components, docs, and generated Figma output.

• Updated theme token definitions so text-kumo-strong represents high-emphasis text and text-kumo-inactive is lighter/inactive in both light and dark modes.
• Migrated affected UI surfaces from text-kumo-strong to text-kumo-subtle where content is supportive metadata, labels, or secondary text.
• Synced token usage in docs and Figma code generators with the updated semantic text mapping.
