I finally have 5.0 up, which adds an option for windowed mode in the launcher app. It also adds a setting for mouse sensitivity in the main menu and combines rain effects and draw distance into something called "Performance Mode" (for slow computers). I also added a +2 damage bonus for melee weapons for the current player only to help balance out melee characters.
I never put in a mouse sensitivity option before now because rotating used to increase crosshair size.
There are also a couple of other fixes in the world editor, etc.
