15.0.0 changes

[Semigradsky]

By doc, I see that you use semver - https://github.com/algolia/react-element-to-jsx-string#release

But I don't see any breaking changes in CHANGELOG - https://github.com/algolia/react-element-to-jsx-string/blob/master/CHANGELOG.md
A bug fix is just patch version updating. Have any other changes been done?
