I mean this change:
Specifically the number in the orange square, which is related in some vague to the number of posts that have needed review in the last day or so.
When it shows "20" this implies to me that there are 20 outstanding reviews required. Only there aren't. When I click the "20" or the "review" link there are no reviews pending. This used to show the number of edits pending, and I can see the case for making it show the number of pending reviews of all kinds. However I can't see the case for making it show effectively random numbers.
