 # ggplot2 2.1.0.9000 
 
+*   `geom_boxplot` gain new `outlier.fill` argument for controlling the fill of
+  outlier points independently of the alpha of the boxes.
+  Analogous to outlier.colour, outlier.shape, etc.
+  (@schloerke, #1787).
+
 *   Overhaul of how discrete missing values are treated (#1584). The underlying 
     principle is that we can naturally represent missing values on discrete 
     variables (by treating just like another level), so by default
