how to access all revisions of Rapidminer

berkaykarakan

I am a doctoral student and I am currently  working on a research related to software repository mining. In my previous research I analyzed a revision of RapidMiner's source code from sourceforge. Now I am expanding my research and trying to analyze annual revisions from beginning of development of RapidMiner. But I realized RapidMiner's source code is not available on sourceforge anymore and it moved to github. But you don't have the previous revisions on the github. Is there a way that I can access all revisions of RapidMiner studio.

Thank you very much,
Sincerely,
