Stable Releases

v0.14.0:

Bumped target Swift version to 4.2.

v0.13.0:

Bumped target Swift version to 4.1.
Renamed JointLinkType to JointLink.
Removed body parameter from init from body component classes.

v0.12.0:

Fixing me meddling w/ pushed tags gone wrong ‌‌ఠి.ఠిన

v0.11.0:

Deprecated methods where removed.
Adding optional plasticity settings to internal springs and spring body joints. Plasticity permanently deforms a spring's resting distance over time as it stretches past a limiting yield. Plasticity is disabled by default.
Correcting parameter lables/orderings in SpringComponent.
Adding method Body.withComponent<T: BodyComponent>(ofType:, do:) that fetches a body component of a specified type and passes it to a closure, if it exists within a body.
Fixing Body.updateAABB() w/ non-static bodies w/ forceUpdate flag set to false.
Fixing World.update() calling Body.updateEdgesAndNormals() one more time than necessary.

v0.10.0:

This is a breaking release. See bellow BodyComponent and CollisionObserver changes.

Adding World.relaxWorld() and World.relaxBodies() that allows relaxing all/a set of bodies into a more proper rest shape that will not 'pop' into their rest shape when starting to simulate. Can be called at any time during simulaton.
Making BodyComponent a protocol instead of a class.
Removing deprecated CollisionObserver.bodiesDidCollide(_ info: BodyCollisionInformation) protocol method.

v0.9.1:

Adding macOS to supported platforms.

v0.9.0:

This release affects behavior of simulations, specially ones using EdgeJointLinks!

Allowing rest distance of internal body springs to be expressed using RestDistance, same way as body joints.
Correcting implementation of edge link to properly calculate the mass of the link, and to apply proper torque on links that lie exactly half-way across the edge. This makes the edge act in a more natural way by applying proper torque to the affected body, as well as making it behave exactly as a PointJointLink when set at edge ratio 0 or 1.

v0.8.0:

Replacing '...' operator for ranged resting distance for body constraints with '<->' operator.
Marking Vector2's inlineable implementations with @inline(__always) instead of @_transparent (easier to debug, as well).

v0.5.1:

Using unchecked arithmetic operators in some tight loops that we know won't overlow under reasonable circumstances.

v0.5.0:

Making corrections to method parameter labeling on Vector2 methods to make them more idiomatic to swift.
Adding World.bodiesIntersecting(closedShape:at:) to query bodies that intersect a specified closed shape in world space.
Adding @_transparent annotations to some members of Vector2 that really don't have to be opaque.

Note: Some operations with transformation of Vector2 lists using ClosedShape w/ rotations might become slightly more imprecise due to usage of Matrices to reduce calls to cos/sin.

v0.4.0:

Fixing crash issue with nan floats generated during body point mass normal calculation.
Adding support for Vector2 affine transformations using simd to allow speeding up operations.
Now the optimized build builds with -Owholemodule.
Added ClosedShape.create static method.

v0.3.0:

Re-working API of ClosedShape to flow more naturally when coding.
Re-working BodyJoint.restDistance property to be an enumeration with two distinct values: case fixed(CGFloat) and case ranged(min: CGFloat, max: CGFloat). This change simply aims to collapse the old restDistance and maxRestDistance into a more cohese format.
- This enum can be created by int/double literals and from the range operator ... between two CGFloat values.
Adding a small fix for a case where NaN would cause crashes during collision resolving.

v0.2.0:

First public Cocoapods release.
