1.3.3

• PMTweenPhysicsSystem (used internally by PMTweenPhysicsUnit) now uses a fixed timestep, which though rudimentary, helps smooth out tween value jittering
• Fixed bug with physics timer not properly removed

1.3.2

• PMTweenPhysicsUnit now updates its physics system independently of property updates, at a frequency of 120 fps by default (to provide double the resolution of a normal 60fps app). This can be changed by PMTweenPhysicsUnit's new property physicsTimerInterval.
• PMTweenPhysicsSystem now handles friction values with less accumulated error.
• PMTweenPhysicsUnit's velocity is now expressed in units per second. Prior to this the velocity acted as units per frame, which obviously caused inconsistent simulations.

1.3.1

• Updated project architecture to use single header import
• Fixed string equality check in PMTweenSupport when comparing keyPaths
• Miscellaneous project cleanup

1.3.0

• Added support for CGVector structs as property tweening targets.
• Added support for tvOS as a target.
• Updated init methods to use instancetype
• Changed minimum iOS target to 7.0.

1.2.0

• Implemented additive animation in PMTweenUnit!
• Updated PMTweenObjectUpdater to provide additive updating support.
• Updated tests.
• Updated Examples project to include additive demos.

1.1.2

• Fixed multiple tweens targeting same object property incorrectly overriding initial value of first tween.

1.1.1

• Fixed PMTweenUnit and PMTweenPhysicsUnit failing to tween object properties specified by a single-element keyPath.
• Fixed NSNumber object properties with a nil value not tweening. Such properties are now initialized with the specified starting value during the init method.
• Changed all init methods to return instancetype instead of id.
• More tests.

1.1.0

• Added PMTweenPhysicsUnit and PMTweenPhysicsSystem classes to provide dynamic, physics-based tweening! PMTweenPhysicsUnit adopts PMTweening, so you get all the standard PMTween functionality – use it in groups and sequences, add reversing, pause it, etc. See the documentation and examples project for more info.
• Fixed bug where PMTweening classes set to reversing wouldn't reverse properly inside a PMTweenGroup that wasn't itself reversing.
• currentValue property wasn't being set to startingValue in PMTweenUnit on setup.
• New tests.
• Updated examples project.

1.0.1

• PMTweenBeat: Fixed this class not having a default tempo or setting child tween tempos to nil.
• PMTweenGroup: Base init method was not calling setTempo.

First release!
