-=-=-=-=-=-=-=-=-=-=-=-=-= -New Vehicle (Based on Bullet's RaycastVehicle) - Vehiclebody/VehicleWheel. Demo will come soon, old vehicle (CarBody) will go away soon too. -A lot of fixes to the 3D physics engine -Added KinematicBody with demo -Fixed the space query API for 2D (demo will come soon). 3D is WIP. -Fixed long-standing bug with body_enter/body_exit for Area and Area2D -Performance variables now includes physics (active bodies, collision pairs and islands) -Ability to see what's inside of instanced scenes! -Fixed Blend Shapes (no bs+skeleton yet) -Added an Android JavaClassWrapper singleton for using Android native classes directly from GDScript. This is very Alpha!
