So it looks like as you tell that the OpenATV Team, OpenPLi Teams are doing no modifications on their version of enigma2 since the enigma2 was closed source... hum... look at their git.
It's just two different forks, as well as we could tell that MastaG's OpenPLi was based on Pyro,... humm... strange that's also the one for OE2.6... Pyro (DreamOne/DreamTwo/DreamSeven,
You just miss that OpenPLi/OpenATV etc teams also develop their enigma2 fork.. so they perhaps have OE3.0 then ;o), with what they added up, and we cannot compare as the other one is Closed source LOL.
