What are the Differences Between Juggernaut & Juggernaut 2.0?

Hi. I see many people referring to the Juggernaut program but then when I look for more information, it is frequently referred to as the Juggernaut 2.0 (which seems to be different from Juggernaut AI, which appears to be the version for your cell phone).

Does anyone know if there are substantial differences between Juggernaut and 2.0? I think I understand the various waves and put together a spreadsheet to track my progress, but was curious if the 2.0 version is better than the original and why. Thanks
