 ### Change
 - Revert change that would cause the root tiles to "trickle" in over time if the root is empty and uses an "ADD" refinement. Tiles will now only render once a full set of child tiles can be rendered.
+- Update "BatchedTilesPlugin" to rely on three.js r170, leverage new copy capabilities.
