Broken version warning
Executing org-drill gives:
"Warning: org-drill requires org mode 7.9.3f or newer. Scheduling of failed cards will not work correctly with older versions of org mode. Your org mode version (7.9.3f) appears to be older than 7.9.3f. Please consider installing a more recent version of org mode."
This doesn't make sense. But: Are my cards in danger?
org-version: Org-mode version 7.9.3f (release_7.9.3f-17-g7524ef @ ... )
