# 2.1.0
This minor release introduces new implicit animation APIs. These APIs provide a migration path from
existing UIView `animateWithDuration:...` code.
## New features
New APIs for writing implicit animations in UIView style:
```swift
animator.animate(with: timing) {
view.alpha = 0
}
```
## Source changes
* [Add a unit test verifying that the completion handler is called when duration == 0. (#34)](https://github.com/material-motion/motion-animator-objc/commit/81b140a9b8bd412443fa6822c0838db1a49585a8) (featherless)

## API changes
### MDMMotionAnimator
**new** method: `animateWithTiming:animations:`

# 2.0.2
This patch release includes minor fixes for CocoaPods unit tests.
CocoaPods Swift modules require that header dependencies be imported using `<>` notation.
## Source changes
* [Use <> framework import for MDMMotionAnimator.h in order to support module builds. (#28)](https://github.com/material-motion/motion-animator-objc/commit/f8fd0506320c31e1c471477639332b2ccb6b09fc) (featherless)

# 2.0.0
This major release includes several new APIs, bug fixes, and internal cleanup.
## Breaking changes
The animator now adds non-additive animations with the keyPath as the animation key. This is a
behavioral change in that animations will now remove the current animation with the same key.
## Bug fixes
Implicit animations are no longer created when adding animations within a UIView animation block.
## New features
New keypath constants:
- backgroundColor
- position
- rotation
- strokeStart
- strokeEnd
New APIs on CATransaction for setting a transaction-specific timeScaleFactor:
```swift
CATransaction.begin()
CATransaction.mdm_setTimeScaleFactor(0.5)
animator.animate...
CATransaction.commit()
```
## Source changes
* [Add support for customizing the timeScaleFactor as part of a CATransaction (#25)](https://github.com/material-motion/motion-animator-objc/commit/17601b94b19320eb4542fca12ba1fa5a2b487271) (featherless)
