SP3, currently at release candidate one, added an almost unlimited world size. Magnet, thruster and emitter settings were added, along with a corresponding magnetic option, as well as the option to add an infinite bouyancy plane to the model. Joypad button and keyboard support has been added through joystick emulation, and ruby script support (With global variables) for control of the simulation has brought unlimited possibilities for real-time interactivity. A new, breakable fixed joint was also added, for connecting thrusters and emitters to parent objects, and for breakable environments/objects. A recording and exporting option was also added, for rendering the simulation.
