The documentation for org-agenda-custom-commands <https://orgmode.org/worg/org-tutorials/org-custom-agenda-commands.html> at https://orgmode.org/worg/org-tutorials/org-custom-agenda-commands.html uses
org-agenda-ndays in the customization instead of org-agenda-span org-agenda-ndays is deprecated in org-version 9. Can somebody update it because it took me an embarrassingly long time to figure out what was wrong with my customization.
