+## NEW FEATURES
+
+* Added `inherit` argument for all `add_()` functions to avoid inheriting attributes from `plot_ly()`.
+* Added the `add_fun()` function to add layers to a plot without modifying the original data associated with a plotly object.
+* Added the `add_annotations()` function to make it easier to add annotations.
+* Added the `layerData` argument to `ggplotly()` to make it possible to retrieve the data from a particular __ggplot2__ layer.
