Hi Vojtěch! The roadmap is referring to "react-navigation" - what we believe and certainly hope will be the end of navigation related API thrashing in the React Native community. ex-navigation is going to stick around until we’re confident that react-navigation can fully superscede it. We are working on providing a clear migration path from ex-navigation to react-navigation, but understand that not everybody can migrate immediately because neither can we, and we use it on several projects. If for whatever reason ex-navigation users decide that they would like to stick with it, we could hand the project over once react-navigation has surpassed ex-navigation in terms of stability and feature completeness.
