Notable new functionality

• Support for double precision simulation for large worlds (see announcement)
• Performance optimization that allows solving large islands on multiple threads (see announcement)
• Vehicles now support suspensions that are at an angle with the vehicle body (instead of 90 degrees)
• Supporting cylinder based wheels for vehicles
• Experimental motor cycle physics (see announcement)
• CharacterVirtual can now move relative to a moving object (e.g. a space ship)
• Added 2D physics example
• Added functionality to estimate the collision impulse in the contact added callback
• Added a JobSystemWithBarrier class that makes it easier to integrate with your own job system
• Support for 32-bit object layers to allow easier integration with existing collision filtering systems
