1.3 patch was made by RA2.. but requested by ACAMS I think, he said it was a fight and a half to get that from them... thats why asking for the source code is seemingly pointless
but it is official none the less, it just doesnt edit the number written in the credits
1.4 is mine, I refered to it as u1.4 but its slowly taking off, it basically enabled the AI parts, added preview images to them (they normally lacked on some) fixed names (some had odd asterisk's in names and such) and enabled the 140cm extender too.
