I am not trolling, as I remember, alf1 started the pre alpha builds, then adamg continued, as I said, the numbers confused me.
It doesn't really matter, try them, but they are both pre alpha, so expect problems.
Actually gendo started them first then me then afl1
Gendo stopped after I made my first release
I asked afl1 if he would like to combine our repositories and releases so there was less confusion for users and so it was less maintainence for the both of us as sometimes he will fix the latest code and then at other times I will, we both benefit from the collaboration and so do users.
Now kszaq is also concentrating on 9.x so there is even greater collaboration now as everyone is upstreaming their contributions to a single location.
Version numbers are developer specific and not related in anyway to any official version.
