 *Changed*
 +  The order in which sorting functions is applied has been reversed.  For example, ~:sort '(todo priority date)~ now does what ~:sort '(date priority todo)~ did in earlier versions.  (This change is made to enable the new ~reverse~ sorting method.)  Users who have customized =org-ql-views= will need to update the stored views' sorting methods to preserve the desired sort order.
