Licensing stores statistics about how many customers have updated to the new version of your software. These numbers are fairly accurate, but not 100%.
To view detailed information click the More link next to where it says Updates.
The percentage of installations that have been updated is displayed in a progress bar.
In addition to the progress bar, a line chart is displayed that shows the number of updates over time.
This is limited to show the first 14 days of updates. A pie chart is also displayed showing up to the top 5 versions your customers have updated from when installing the new version.
