13.0.0-alpha.1 (2021-09-13)

Features

• Use concurrent React when available (#937) (c888cb6)

BREAKING CHANGES

• If you have React 18 installed, we'll use the new createRoot API by default which comes with a set of changes while also enabling support for concurrent features.
  To can opt-out of this change by using render(ui, { legacyRoot: true } ). But be aware that the legacy root API is deprecated in React 18 and its usage will trigger console warnings.
