We never had another component
We only migrated the codebase (~683615 Lines) to something what Joomla required due their heavy framework changes. We have to do the same work for any future Joomla version. Adapt the codebase to be compatible with the current stable Joomla version. For the moment is it Joomla 2.5 ... and maybe if we have finished that we can go over to the latest available Joomla version ... maybe 3.0 or maybe 3.5 or maybe 6.0, i don´t know that right now.
