It has 4 changes compared to b23: Screen fade-ins and fade-outs are faster; Tactical Combat is turned on by default in the Game Setup screen; missiles default to x2 shot racks instead of x5 in the Design Dock console; and the cheat ALT+menlo gives 30.000 instead of 9.999 research points. The zip file includes a changelog and the source code of the 1.40 patch.
