== WDQ data dump updates == 

 Hi, I am greatly interested in your WDQ query interface and currently testing it. It says "the data used here is from WikiData "dumps", so it can be a few hours old". The question is how old it is or can be? and is there a way to find the timestamp of the current dump? The question arose from this discussion in Russian. Bridges across the Danube returns 38 items. It is much lesser than should be because many bridges entries do not have P177 (crosses) set at all or having it set wrongly. Yet I manually set this property for one of bridges at Sep. 11. Today is Sep. 16 and still nothing is changed in query results.
