Prerelease: no

Release notes:

Minor Changes

• 50d4251: Add DatePicker component built on react-day-picker v9

New Component: DatePicker

• Three selection modes: single, multiple, and range
• Forwards all react-day-picker props for maximum flexibility
• Styled with Kumo tokens (no external CSS import needed)
• Supports localization via date-fns locales
• Supports timezone via timeZone prop
• Custom modifiers for highlighting specific dates
• Footer prop for messages/usage limits
• Accessible keyboard navigation with Kumo-styled focus rings

Usage:

// Single date


// Multiple dates


// Date range

Composing with Popover:

Pick a date

Note: Consider using DatePicker with mode="range" instead of DateRangePicker for new projects - it offers more flexibility and a smaller bundle size.

Internal changes:

• Added react-day-picker v9 as a dependency
• Updated lint rule to allow components without KUMO\_\*\_VARIANTS exports
• Updated component registry codegen to handle variant-less components
• Disabled jsx-a11y/no-autofocus rule (intentional prop forwarding)

• 93361ed: feat(clipboard-text): add slide animation with tooltip on copy

Patch Changes

• c71bd9b: Updated the MenuBar so its child buttons align with the container’s outer corners.

• 46ecf42: Fix kumo add to consolidate imports from @cloudflare/kumo into a single statement using inline type syntax.

Previously, running kumo add DeleteResource would produce non-conformant code with duplicate imports:

import { Dialog, DialogRoot } from "@cloudflare/kumo";
import { Input } from "@cloudflare/kumo";
import { Button } from "@cloudflare/kumo";

Now it produces a single consolidated import:

import {
Dialog,
DialogRoot,
Input,
Button,
type DialogProps,
} from "@cloudflare/kumo";

This satisfies ESLint's import/no-duplicates rule with prefer-inline: true.

• a9167fa: Fix z-index stacking issues with nested portaled components (e.g., Select inside Dialog)
• Remove unnecessary z-index values from Dialog, Select, Combobox, and Dropdown
• Delete .z-modal { z-index: 9999 } - DOM order now handles stacking naturally
• Components opened later correctly appear on top without z-index wars

• f02494d: fix(dropdown): improve external link detection to handle http:// and protocol-relative urls

updated the external link check to use a regex that matches https://, http://, and protocol-relative URLs (//). previously only https:// links opened in a new tab.
