 ScrollInfo Node Plugin Change History
 =====================================

+
+* Added an `isNodeOnscreen()` method that returns `true` if the given node is
+  within the visible bounds of the viewport, `false` otherwise. [Ryan Grove]
+
+* Improved the performance of `getOffscreenNodes()` and `getOnscreenNodes()`.
+  [Ryan Grove]
+
+* Fixed a bug that caused `getOffscreenNodes()` and `getOnscreenNodes()` to
+  return incorrect information when used on a scrollable node rather than the
