This entry was showing alright in org-agenda in Org 7.8, if I remember correctly.
** Dinner <2016-02-26 Fri 12:00-13:30>
Not any more in Org 8.2. Now, it seems I need to have it this way to show up in org-agenda:
** TODO Dinner <2016-02-26 Fri 12:00-13:30>
How could I show appointments (items without a TODO keyword) in new versions of org-agenda?
