Significant mask and matte performance improvements by only calling saveLayer() on the intersection bounds of the content and mask/matte.
Added support for dynamic properties on rectangles, gradient colors, and gradient fill opacity.
Added support for inverted and intersect masks.
Improved support for multiple masks per layer.
Added support for optimized bodymovin json with static transforms removed (v5.5.0+).
Added support for optimized bodymovin json that will omit duplicated vertex out points to reduce json file size (v5.5.0+).
Added support for centered, multiline text, and emojis.
Added support for masked text.
Added support for skew and skew angle in transforms.
Added support for markers. You can now call setMinFrame, setMaxFrame and setMinAndMaxFrame with a marker name.
Added support for hidden layers and properties (the eye button in After Effects).
Added support for multiple trim paths to be applied on a shape.
Removed all memory allocations during playback including autoboxing.
Replaced enableHardwareAcceleration with a new setRenderMode API because it has a third (Automatic) option. Refer to the docs for more info.
Added an XML attr for animation speed (lottie_speed).
Removed the recycleBitmaps() API because it is not neccesary anymore.
Prevented invalidateSelf() from being called and recalculating bounds many times per frame.

Only redraw the animation when a value changed. This will have a major impact on animations that are static for part of their playback.
Optimized keyframes to recalculate values less frequently
Optimized static identity transforms so their matrix doesn't get recalculated on every frame.
Ensure that the last frame is played when setMaxFrame is called.
Prevent strokes from drawing when the scale is 0.
Prevented minFrame from being larger than maxFrame.
Return the correct (previous) bitmap when updating the BitmapAssetManager.
Properly use the in-memory cache for network animations.
Prevented color animations from interpolating before/after the start/end colors even if their interpolator goes <0 or >1.
Annotate fetchBitmap() as @Nullable
Fixed a bug in the local file cache that would save it with the wrong extensions.
Fixed a crash when an animation was missing gradient fill type.
Prevent shapes that have different numbers of control points in different keyframes from crashing.
Fixed an IndexOutOfBoundsException.
Pause Lottie in onVisibilityChanged.
Properly limited the LRU cache an enable its maximum size to be configured.
Prevented the cache from returning null values after a key was cleared.
Properly closed JsonReader in all cases.
Fixed text alignment for scaled text when drawn using fonts.
Use FutureTask rather than polling for composition parsing to complete.
[Sample App] Fixed Lottiefiles integration.
