+
+### Timeline
+
+- Select event now triggers repeatedly when selecting an already selected item.
+- Renamed `Timeline.repaint()` to `Timeline.redraw()` to be consistent with
+  the other visualisations of vis.js.
+- Fixed `Timeline.clear()` not resetting a configured `options.start` and 
+  `options.end`.
+
+### Graph
+
+- Fixed error with zero nodes with hierarchical layout.
+- Added focusOnNode function.
+- Added hover option.
+- Added hover events (hoverNode, blurNode).
+
+### Graph3D
+
+- Ported Graph3D from Chap Links Library.

+  The class name of the Graph3d is <code>vis.Graph3d</code>.

+  Graph3d can load data from an <code>Array</code>, a <code>DataSet</code> or a <code>DataView</code>.
