+Reports Subtotals
+^^^^^^^^^^^^^^^^^
+Reports now allow group subtotals and grand totals.  By checking the
+new "Calculate grouping subtotals" checkbox under "Output Options",
+a new unlabeled row or column is created with the subtotals for each
+grouping and an unlabeled grand total row or column.
+
+This takes advantage of PostreSQL's built-in ROLLUP feature.  See the
+PostgreSQL documentation for details:
