v4.0.0 was a complete rewrite that utilizes React v16 Portal API. However, we dropped support for older Reacts. That can be a problem for library authors that still want to support older Reacts.

So, version v4.1.0. adds a fallback in case that Portal API doesn't exist. Now you can use the same react-portal with React v16 and v15.

It removes React.PropTypes and uses prop-types lib instead.

#105

• It doesn't rely on internal modules or React, so future React versions should not break this module again.
• It removes shallowCompare() since it doesn't really do anything
• It removes support to style (inline styles and className) the main react-portal div. Use a wrapper div (or other element) instead. This is a braking change if you rely on this functionality; thus, major release.

openByClickOn element is not wrapped by unnecessary div element anymore

• cleaner markup
• className openByClickOn removed
• this is good if this element is something like button that should be inlined
• this is a BC change; thus, major release
