&gt;  Now there are two reasons I can think of this happening<p>They are also churning at a pretty insane rate due their release schedule.  I did a very basic analysis of their repos at<p><a href="http:&#x2F;&#x2F;gitsense.github.io&#x2F;blog&#x2F;motion-bubble-charts.html" rel="nofollow">http:&#x2F;&#x2F;gitsense.github.io&#x2F;blog&#x2F;motion-bubble-charts.html</a><p>And this is the churn for this month in their master and 8-7-stable branch<p><a href="http:&#x2F;&#x2F;imgur.com&#x2F;PfyFrzS" rel="nofollow">http:&#x2F;&#x2F;imgur.com&#x2F;PfyFrzS</a><p>I also included the <a href="https:&#x2F;&#x2F;github.com&#x2F;atom&#x2F;atom" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;atom&#x2F;atom</a> master branch (blue line) for comparison.<p>In order to get a better picture what what&#x27;s going on, I&#x27;ll need to cross reference the churn to security issues, but this isn&#x27;t something my tool will support until later in the year.
