There was an update around the 17th or 18th. Now, I see that all of the sites have been updated as of the 25th. I know that there was a time when a weekly or every-two-week update cycle was planned, but I couldn't find any confirmation of this having been implemented.
The Data Explorer FAQ still says monthly, but there had been a delay of a few months at one point, so I'm not entirely sure that the FAQ is trustworthy on all points.
Every other post that I've found about the Data Explorer is at least a few months old, and this appears to be a recent change.
