So just how many times has the addon been downloaded recently?
I got charts for 2014 and 2015 to show:
The spike in July of 2015 was about 2600 downloads in a single day!
Whats is curious is the stuff at the bottom of the charts.
After a release is made, predictably, the old version drops off dramatically and the new version spikes up. But there are rather steady dribs and drabs of old software being sucked for long periods of time.
