Android platform

🎉 DirectlyManipulable now uses AnchorPointAdjustable interaction to ensure pivot always aligns with the gesture centroid.

🎉 ReactiveProperty instances are now shared for the same target property. This allows interactions to affect each other by reading and writing to the same properties.

🎉 Spring is now an interaction.

📝 Tossable interaction

ReactiveProperty<Float[]> destination = ReactiveProperty.of(new Float[]{500f, 500f});
runtime.addInteraction(new Tossable(destination), target);

Apple platforms

🎉 Implemented arc move and an arc move example.

Web frameworks

🎉 Built prototype of createDragStream() atop MotionObservable, with translated and read operators

Tooling

🎉 mdm git tree output now includes the diff url:
