v1.1.0

• Null annotate library
• Use readonly structs
• Enable SourceLink and deterministic builds

v1.0.0

Initial release 🎉

v0.6.0

• Rename Simulation.GetTotalEnergy to GetTotalKineticEnergy as it doesn't consider potential energy.
• Add optional maximum distance to ColoumbForce.
• Simplify ILocalForce and related internal code.
• Fix double-calculation in ColoumbForce. Turns out as a nice optimisation, though requires re-calibrating physical constants.

v0.5.0

• Replace PointMass.Damping with new ViscousForce force.
• Add PointMass.ApplyImpulse(Vector2f) for one-off effects that work independent of the update time step.
• Make more properties settable:
  • Spring.Length
  • Spring.K
  • PointMass.Velocity
• Optimisation for FixedTimeStepUpdater.

v0.4.1

Simulation.Remove methods no longer throw if item being removed isn't found.

v0.4.0

Considerable changes to public API.

• Merge Physics and Graph classes into new Simulation class
• Remove Boing.Forces namespace, hoisting contained types to the parent Boing namespace
• Rename Node to PointMass
• Rename Edge to Spring
• Rename IForce to IGlobalForce
• Introduce new ILocalForce, implemented by Spring
• Remove HookeForce which is now replaced by the local equivalent Spring
• Consolidate Add/Remove methods on Simulation class
• Add FixedTimeStepUpdater
• Increase required version of the .NET Framework from 2.0 to 3.5

Internally, physics simulation accumulates forces rather than accelerations.

v0.3.2

Fix invalid precondition in Rectangle2f.
Fix bug in Rectangle2f corner positions.

v0.3.1

Fix bug in Rectangle2f.TryIntersect.
Modify assembly metadata.

v0.3.0

Add LineSegment2f and Rectangle2f types.

v0.2.0

• Make Node.Position settable.
• Modify Node constructor to take Nullable<Vector2f> for initial position.
• Migrate code to C# 6 (no change to public API)
