+    Optional attributes to group the summary by. The ``groupby`` elements are
+    defined in the collector YML settings. Therefore, one can group the
+    result using any of the ``groupby`` attributes defined in the collector
+    settings of CloudKitty. Besides those attributes, by default, starting
+    in CloudKitty ``2024.1`` release, we will have the following new groupby
+    options: (i) time: to group data hourly; (ii) time-d: to group data
+    by day of the year; (iii) time-w: to group data by week of the year;
+    (iv) time-m: to group data by month; and, (v) time-y: to group data by
+    year. If you have old data in CloudKitty and you wish to use these
+    group by methods, you will need to reprocess the desired timeframe.
+    The `groupby` options ``time-d``, ``time-w``, ``time-m``, ``time-y`` are the
+    short versions of the following `groupby` options ``day_of_the_year``,
+    ``week_of_the_year``, ``month``, and ``year`` respectively.

+    Introduce new default groupby options: (i) time: to group data hourly.
+    The actual group by process will depend on the ``period`` parameter. The
+    default value is ``3600``, which represents one hour; (ii) time-d: to
+    group data by day of the year; (iii) time-w: to group data by week of
+    the year; (iv) time-m: to group data by month; and, (v) time-y: to group
+    data by year. If you have old data in CloudKitty and you wish to use
+    these group by methods, you will need to reprocess the desired timeframe.
