- TODO: Enumerate changes.
+This minor release introduces support for animating more key paths and support for drop-in UIView animation API replacements.
 
+## New features
+
+The MotionAnimator can now implicitly animate the following CALayer properties: `anchorPoint`, `borderWidth`, `borderColor`, `shadowColor`, and `zPosition`.
+
+There are now UIKit equivalency APIs that can be used as drop-in replacements for existing UIView animation code.
+
