group, pivot, and treegroup now allow you to specify aggregate functions. ...like sum(), count() and so on. Additional interesting ones are only() (which deliberately crashes if there's more than one value, indicating that you should revise your query), cat() (which concatenates all the values into a single string), and first() (which just pulls the first value when there's more than one).
