#Changelog
## Version 0.7.0 (March, 2018)
### Added
- Dedicated Sphere vs Capsule collision detection algorithm.
- Dedicated Capsule vs Capsule collision detection algorithm.
- Allow a Rigid Body to have zero mass (for static bodies for instance).
- Add single frame memory allocator for faster memory allocation in a frame.
- Make possible to have a profiler per DynamicsWorld instead of a unique one.
- Make possible to use your own allocation/deallocation methods instead of default malloc/free
- Make possible to display the AABB of the bodies in the testbed application.
- Add RigidBody::setInverseLocalInertiaTensor() method to directly set the inverse inertia tensor of a rigid body.
- More unit tests have been added
### Changed
- Use single-shot contact manifold computation instead of incremental across several frames.
- Replace the EPA narrow-phase collision detection with SAT algorithm.
- The collision detection is now faster and more robust.
- Code has been refactored such that we do not use STL containers anymore.
- The way to create a ConvexMeshShape has changed (see the user manual)
- The vertex indices stride has changed in the TriangleVertexArray for ConvexMeshShape (see the API documentation)
- The raycasting of a ConvexMeshShape does not use GJK algorithm anymore.
- The test do detect if a point is inside of a ConvexMeshShape does not use GJK algorithm anymore.
- A lot of optimizations have been performed and the library is now faster.
- Documentation has been updated
### Removed
- Quaternion constructor with Euler angles has been removed. The Quaternion::fromEulerAngles() method should be used instead.

## Version 0.6.0 (April 15, 2016)
### Added
- Support for static concave triangular mesh collision shape.
- Support for height field collision shape.
- Support for rolling resistance.
- It is now possible to change the local scaling of a collision shape.
- Add new constructor of ConvexMeshShape that accepts a triangular mesh.
- It is now easier to use your own narrow-phase collision detection algorithm.
- The CollisionWorld and DynamicsWorld now automatically destroys bodies and joints that have not been destroyed at the end.
- New testbed application with demo scenes.
### Changed
- The DynamicsWorld::update() method now takes the time step for the next simulation step in parameter.
## Version 0.5.0 (March 4, 2015)
### Added
- It is now possible to use multiple collision shapes per body.
- Ray casting support.
- Add methods to check if a point is inside a body or a proxy shape.
- Add collision filtering using collision categories (with bit masks).
- It is possible to attach user data to a body or a proxy shape.
- It is now possible to create a quaternion using Euler angles.
- It now possible to activate of deactivate a body.
- Differentiation between dynamic, kinematic and static bodies.
- Gravity can now be changed after the creation of the world.
- The center of mass and inertia tensor of a body can be set manually (center of mass can be different from body origin).
- Add a simulation step callback in the EventListener class that is called at each internal physics tick.
- Add methods to transform points/vectors from/into local-space/world-space coordinates of a body.
- Add CollisionWorld::testAABBOverlap() method to test overlap between two bodies or two proxy shapes.
- Add a ray casting example.

### Changed

## Version 0.4.0 (October 7, 2013)
### Added
- Add collision shapes (Capsule, Convex Mesh).
- Add joints (Ball and Socket, Hinge, Slider, Fixed).
- Add sleeping technique for inactive bodies.
- Add velocity damping.
- It is now easier to apply force and torque to a rigid body.
- Add the EventListener class to allow the user to be notified when some events occur (contacts, …).
- Add examples for the joints and collision shapes.
- Make possible to modify the collision margin of some collision shapes.
- Add a Material class to keep track of the properties of a rigid body (friction coefficient, bounciness, …).
- Add a hierarchical real-time profiler.
### Changed
- Collision shapes now use the internal memory allocator.
- New internal memory allocator.
### Removed
- Remove the world gravity force from the external force of rigid bodies and allow the user to disable the gravity on a given body.
- Reduce the allocated memory of the broad-phase when several bodies are removed from the world.
### Fixed
- Fix issue in the Sweep-And-Prune broad-phase collision detection (thanks to Aleksi Sapon).
- Fix issue in the contact solver resulting in less jittering.
## Version 0.3.0
### Added
- Implementation of a dedicated collision detection algorithm for spheres against spheres instead of using GJK/EPA algorithm.
- Make possible to use a unique instance of a collision shape for multiple rigid bodies.
- Create the API documentation using Doxygen.

### Changed
- The Sweep-and-Prune broad-phase collision detection algorithm has been rewritten according to the technique described by Pierre Terdiman at http://www.codercorner.com/SAP.pdf to be much more efficient than the previous naive implementation.
