Changes for version 2.4.1

API Changes

• Extended distance joint to have a minimum and maximum limit.
• Removed rope joint. Use the distance joint instead.
• B2_USER_SETTINGS and b2_user_settings.h can control user data, length units, and maximum polygon vertices.
• Default user data is now uintptr_t instead of void*
• b2FixtureDef::restitutionThreshold lets you set the restitution velocity threshold per fixture.

BREAKING Changes

• BREAKING: distance joint 0 stiffness now means the spring is turned off rather than making the joint rigid.
• BREAKING: distance joint minimum and maximum must be set correctly to get old behavior.

Infrastructure

• Library installation function available in CMake.
• Shared library (DLL) option available.
• Bug fixes
