I was looking at the revision history of the question "Is all ordinary mathematics contained in high school mathematics?" on MathOverflow (revision history, edit suggestion). I was curious what was actually the difference between the old and the new title - the revision history shows difference between the titles in the two revisions.
So I tried to check SEDE - to see what titles are shown in the
Text field of the
PostHistory table. Then I realized that the edit isn't shown in the PostHistory table at all (among the entries for this post).
The edit was made on July 24 - the database was updated since then. (SEDE shows "Data updated 2 days ago". There were some problems with SEDE, but according to answer there, they should be resolved now: Weekly SEDE refresh stuck at Gaming.SE. When I check the most recent post in database, I see some posts made on July 31.)
