Breaking changes

QuantityButton

The quantity is now a real input, you can type a number instead of only able to click +/- button. To make that work the API had to change, so v11 is a breaking release for this component.

Migration: quantity becomes value, and the two click handlers become one onValueChange that fires for both typing and the buttons (stepping is handled internally now):

{/* before */}
<QuantityButton
  quantity={guests}
  onClickPlus={() => setGuests((n) => n + 1)}
  onClickMinus={() => setGuests((n) => n - 1)}
  min={1}
  max={20}
/>

{/* after */}
<QuantityButton
  value={guests}
  onValueChange={setGuests}
  min={1}
  max={20}
  aria-label="Guests"
/>
