# 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 # Changes for version 2.4.0 ## Infrastructure - Documentation in Doxygen format - CMake build system - Unit test support - Continuous integration testing using Travis CI - Limited use of C++11 (nullptr and override) - Restructured folders and renamed files to better match open-source standards - MIT License - Removed float32 and float64 - Linked the Box2D project to GitHub Sponsors ## Collision - Chain and edge shape must now be one-sided to eliminate ghost collisions - Broad-phase optimizations - Added b2ShapeCast for linear shape casting ## Dynamics - Joint limits are now predictive and not stateful - Experimental 2D cloth (rope) - b2Body::SetActive -> b2Body::SetEnabled - Better support for running multiple worlds - Handle zero density better - The body behaves like a static body - The body is drawn with a red color - Added translation limit to wheel joint - World dump now writes to box2d_dump.inl - Static bodies are never awake - All joints with spring-dampers now use stiffness and damping - Added utility functions to convert frequency and damping ratio to stiffness and damping ## Testbed - Testbed uses dear imgui - glad OpenGL loader - OpenGL 3.3 required # Changes for version 2.3.0 - Polygon creation now computes the convex hull. Vertices no longer need to be ordered. - The convex hull code will merge vertices closer than dm_linearSlop. This may lead to failure on very small polygons. - Added b2MotorJoint. - Bug fixes.
