 ### Changed:
 
+- [MetricMaker cleanup and simplification](https://github.com/yahoo/fili/pull/127)
+    * Simplified raw aggregation makers
+    * `ConstantMaker` now throws an `IllegalArgumentException` wrapping the raw NumberFormatException on a bad argument
+    * `FilteredAggregation` no longer requires a metric name to be passed in. (Aggregation field name is used)
+    * `FilteredAggregationMaker` now accepts a metric to the 'make' method instead of binding at construction time.
+
 - [Used Metric Field accessor to simplify maker code](https://github.com/yahoo/fili/pull/124)
     * Using metric field accessor simplifies and enables streaminess in maker code
