I seen there is 6.x repo so i was thinking to try so i dont know what version of wow i need ??
Tnx and one more thing 3.3.5a-proc is that similar to 3.3.5a db or new
The only branches that “matter” are 6.x and 3.3.5. All the other ones are work in progress that will be merged eventually with one of the other two.
Sry for bother 
is it 6x stable ?
Read the first link I gave you. It answers all your questions.
Yeah it says experimental hmm i already working with 3.3.5a i dont want to wait time playing on 6x if is not stable for playing if u know what i mean
