the official version is 1.3
but the github is the WIP code and you can compile it, for a version the might be BUGGY like a pre-relesse version, it will be updated to an official version when is ready to be one.
thanks
well i hope if SLiV3R is right and the original creators arent working on blarg anymore, other people can freely pick it up from github and develop it further?
i think its very hard tho
