See the release compare page and the changelog for a detailed list of changes.

Migration ⌲

• Behaviour and similarity is in practice the same (a fractional difference from improved accuracy)
• API is the same other than:
  • Matter.Detector replaces Matter.Grid (which is now deprecated but will remain for a short term)

  • Matter.SAT is renamed Matter.Collision
  • Matter.SAT.collides is now Matter.Collision.collides with a slightly different set of arguments
