Org-mode's agenda view is behaving differently for me based on whether I use the Org-mode 8.2.10 that came with my Emacs or 9.1.1 as installed from Elpa. Specifically, on 8.2.10, the default "week" agenda view includes TODO items that are past due, but in 9.1.1, it does not. I am using the exact same configuration in either case. My
init.el is here in case that helps. I would be grateful for any hints as to what might be causing this difference in behavior.
For example, today (2017-09-24), the following overdue todo item would be included in 8.x, but not in 9.x:
* TODO review code DEADLINE: <2017-09-05>
I am using Emacs 25.2.2 from Debian.
