What's with the version numbers?
The sources for the charts are of such varied levels of quality that there are
bound to be mistakes in the way the data is assembled. There is a continual
effort to fix the most obvious problems in the data, and to add in additional
charts as they become available. The version number tracks these changes, so
if an issue is identified it can be tied to the version of the data that it
was fixed in.
The version number of this particular data set is 1.5.0036. There is a
CSV File that lists all the entries.
