 ## 2.1.5
+* crossfilter is loaded by its module name (crossfilter2), not its filename (crossfilter). This is intended to help webpack and other automatic module loaders. This is likely to break requireJS configurations; see [#1304](https://github.com/dc-js/dc.js/issues/1304) for details. ([#1213](https://github.com/dc-js/dc.js/issues/1213), [#1214](https://github.com/dc-js/dc.js/issues/1214), [#1261](https://github.com/dc-js/dc.js/issues/1261), [#1293](https://github.com/dc-js/dc.js/issues/1293), [#1302](https://github.com/dc-js/dc.js/issues/1302))
  * Default capMixin.ordering to sort decreasing by value, to emulate old group.top(N)
- * `numberDisplay` was picking lowest instead of highest value in the case where it was given a regular group
+ * `numberDisplay` should pick the highest value in the case where it is given a regular group
 
 ## 2.1.4
  * Simplified `capMixin.othersGrouper` default implementation by passing the rest of the items as well as those before the cap. This is possible because of [#934](https://github.com/dc-js/dc.js/issues/934) relying on sorting of `group.all()` instead of `group.top()`. The default implementation is now easy to understand and it should be easier to customize (if anyone should want to).
