### Deprecated

The following classes were renamed. You can still use the old classes but when you do, you’ll get a warning in the console.

 - Matrix2x2 - use Matrix2 instead
 - Matrix3x3 - use Matrix3 instead
 - Matrix4x4 - use Matrix4 instead

The following methods in the math classes were deprecated. Most of the methods were shimmed, so you can use them as before - but you’ll get warnings. Don’t worry, there are alternatives, and the warnings should point you in the right direction.

### Breaking changes
 * all addons are now split in packs:
     goo/addons/p2/* -> goo/addons/p2pack/*
     goo/addons/box2d/* -> goo/addons/box2dpack/*
     goo/addons/terrain/* -> goo/addons/terrainpack/*
     goo/addons/cannon/* -> goo/addons/cannonpack/*
     goo/addons/howler/* -> goo/addons/howlerpack/*
     goo/addons/water/* -> goo/addons/waterpack/*
     goo/addons/ammo/* -> goo/addons/ammopack/*
     goo/addons/soundmanager2/* -> goo/addons/soundmanage2pack/*
     goo/addons/gamepad/* -> goo/addons/gamepadpack/*
 * the animation module has been extracted in its own pack:
     Any files which used to be under goo/animation have been relocated to goo/animationpack along with any animation-related handlers.
     To be able to load animations using the dynamic loader you need to require any animation-related handlers (SkeletonHandler, AnimationComponentHandler, AnimationStateHandler, AnimationLayersHandler, AnimationClipHandler) - all of them will register themselves with the dynamic loader.
     Also, the animation system is not pre-included in the world - it will need to be added manually (world.setSystem(new AnimationSystem())) for projects that contain animations.
 * the passes have been extracted in their own pack:
      goo/passpack contains the former goo/renderer/pass/PassLib along with pass-related shaders which used to be in goo/renderer/shaders/ShaderLib, any post-effect related passes (Bloom, Blur, Depth, DOF, DOG, MotionBlur, Nes, SSAO) and the PosteffectsHandler. To be able to load posteffects using the dynamic loader you need to require the PosteffectsHandler (which will register itself).
 * the transform gizmos have been relocated to their own pack, under goo/util/gizmopack

----------------------

 * new wave scripts (src/goo/scripts/newwave) are relocated to the parent folder, replacing some of the older scripts. The old FPCamControlScript, FlyControlScript, OrbitCamControlScript, OrbitNPanControlScript, MouseLookControlScript and WASDControlScript are thus replaced with new style scripts and are not backwards-compatible.
 - EntityUtils.createTypicalEntity has been removed as scheduled; use world.createEntity instead
