-- Confirmation step added when deleting cards.
-- Can now choose to use either local or UTC time when marking tasks as complete.
-- Shows the year of a task on the card if it is not due in
-  the current year.
-- Bugfix: filter definitions dropdown is now scrollable.
-- Bugfix: card content respects the _Text Font_ setting in

-  in unexpected columns when there is an `Other Tags` column.
