Hey, thanks for the effort, however this PR is too big, and it would be risky to merge it alltogether, please separate this in different PRs. 🙏

Remove Body.preStep
Remove Body.postStep

• Cool, please make a PR only for those. Remove deprecated body.preStep and body.postStep #133

Remove Material.name

People still use the name property of the material for debug purposes, unfortunately this can't go. We can remove the @todo Deprecate this comment and just deprecate calling new CANNON.Material('test'), it can become new CANNON.Material({ name: 'test' }) instead.

Remove World.addMaterial
Remove World.materials

• Cool, please make a PR only for those. Remove world.addMaterial #135

Remove World.numObjects

• Cool, please make a PR only for this. Remove deprecated world.numObjects #134

Remove World.rayTest

Need to test this more deeply, please make a PR only for this.

Improve TupleDictionary implementation

Please make a PR only for this explaining the reasoning behind this.

[index.html] Update references to the current location of this repo

• Cool, please make a PR only for this. Update link to the current location of the repo #137

[Shapes] Now an abstract class

Cool, please make a PR only for this.

I think we should do a 1.0 release after this.

Unfortunately the 1.0 goals are much broader, please look at the project objectives in the physics poimandres board.
