Release v8.0.0

This release makes changes to the StateMachines framework, which break compatibility. Projects will need to be modified if using this version or beyond.

• IState, IStateMachine, State, and StateMachine have all been discontinued. Their reliance on state registers to transition to another state was messy, and gave states the explicit capability to interact with one another. This is undesirable.
• IStateT, IStateMachineT, StateT and StateMachineT have been modified. They no longer use a state register, and a state's update methods must now return a clean . This allows enum-based states to operate independently, with their state machine being the only one able to locate the next state to transition to.
• As a result, StateT and IStateT may no longer return null. If a state update should not cause a state transition, return the enum's default value instead. It is recommended to have the enum's 0 value remain unused (don't associate an IStateT with it) and return this where you would previously return null.

Release v7.7.0

Introduced "Variables" namespace, with a series of classes to track variables by reference to a ScriptableObject. This is useful to decouple data and retain flexibility. Classes are based on code shown in Ryan Hipple's Unite Austin 2017 presentation on Game Architecture with ScriptableObjects.

Variables, ScriptableObjects to store a field value

• BoolVariable
• ColorVariable
• DoubleVariable
• FloatVariable
• IntVariable
• StringVariable
• Vector2Variable
• Vector3Variable

References, classes to store a local value or a reference to a Variable

• BoolReference
• ColorReference
• DoubleReference
• FloatReference
• IntReference
• StringReference
• Vector2Reference
• Vector3Reference

(All references have matching custom PropertyDrawers for use in Editor.)

Note: The "StephanHooft.VariableRanges" namespace was removed. Replacing with "StephanHooft.Variables.Ranges" should fix any issues.
