Likely to cause new Flow errors:

• Referencing a react-component typed value in type position will now create a React$RendersExactly<typeof Component> type instead of React$Element<typeof Component> type. All existing usages intended to create an exact react element will now error as a result. Using it as type passed to render type, React.PropsOf, React.PropOf and React.RefOf is unaffected and will not be affected in the future. If you want exact react elements, the only way that doesn't trigger Flow error is by ExactReactElement_DEPRECATED<typeof Component>.

Library Definitions:

• React.Config type is marked as deprecated and will be removed soon. You can create your own equivalent type with

type ReactConfigShim<Props, DefaultProps> = $ReadOnly<{
  ...Omit<Props, $Keys<DefaultProps>>, ...Partial<DefaultProps>
}>;
