A GitHub link is not necessarily the most stable reference, and also appears to only list the top 100. The updated text is intended to make it clear that this lists may not be fully accurate (as JuliaLang does not have full control over it), and inform the user of an alternate method of listing the JuliaLang authorship history through git.
