The interval can at most be one day and at least one hour currently. It has to cleanly divide one day, for rounding reasons.\n\nBecause of technical limitations, this endpoint returns at most 10000 data points. For example, if you select a 90 day window grouped by releases, you will see at most `floor(10k / (90 + 1)) = 109` releases. To get more results, reduce the `statsPeriod`.",
