Ehm.
Major.whatever
whatever == every patch contains different fixes: script fixes or master fixes or launcher fixes etc. and each different fix increases the version by 0.0.0.1
E.g the first english version of Enderal was 1.1.0.0 and the first english patch was 1.1.0.3, since it contains some Script (1.1.0.1), some master (1.1.0.2) and finally Launcher fixes (1.1.0.3).
