+
+### Improved generated document consistency
+
+There was a number of places in code that generated names for different
+resources semi-randomly. That made hard to verify if document has any unexpected
+changes. There was some effort to improve consistency.
+
+(Alexander Mankuta)
+
+
+### Improved gradients
+
+Gradients can have multiple stops to blend more than two colors
+
+Previously, only two colors could be specified in a gradient: the start and end
+colors.  This change allows any number of colors to be specified, along with the
+position between 0 and 1 as to where they should be displayed.
+
+This change also comes with a change to the format of the `fill_gradient` and
+`stroke_gradient` methods.  You can continue to use the old method parameters
+and only specify two colors, or use the new keyword arguments to specify
+arbitrary stops.
+
+As a bonus, if you use the new method style, `apply_transformations` is set true
+automatically.

+### Supported Rubies has changed
+
+* Removed MRI 2.0, JRuby 1.7, and Rubinius support
+* Added MRI 2.4 and JRuby 9k
+
+
+### Catch unexpected manual changes
+
+For a long time changes to manual were hard to spot because it was a manual
+process. There was no way to know for sure if the manual has changed or not.
+
+Now manual changes are caught during build.
