Warning: Accessing PropTypes via the main React package is deprecated

Getting the above warning in 'react-modal-bootstrap'. Please upgrade the react library and import right propTypes.

Also I get the below warning, this one as well is because of react version.
Warning: Style: React.createClass is deprecated and will be removed in version 16. Use plain JavaScript classes instead. If you're not yet ready to migrate, create-react-class is available on npm as a drop-in replacement.
