<p>Not directly, in that <a href="https://stackoverflow.com/a/10971038/6309">it cannot display diff</a>.<br>
You would <a href="https://gist.github.com/thbar/4943276" rel="nofollow noreferrer">need an external diff</a> like <a href="http://www.qtrac.eu/diffpdf.html" rel="nofollow noreferrer"><strong><code>diffpdf</code></strong></a> for that.</p>

  <p>Maybe github can provide the version control for Arxiv.org.</p>

<p>Right now, GitHub is not used by Arxiv.org. Their <a href="http://arxiv.org/new" rel="nofollow noreferrer">"new" page</a> mentions in 2008:</p>

<blockquote>
  <p>We have implemented version control for papers submitted prior to November 1997 in the same way as for papers submitted later.</p>
</blockquote>

<p>In 2011: </p>

<blockquote>
  <p><a href="http://arxiv.org/help/bulk_data_s3" rel="nofollow noreferrer">Bulk data available on Amazon S3</a>: The bulk data available for download from Amazon S3 has been extended to include both PDF and source files of the latest versions of all arXiv articles.</p>

does github support version history for pdf files?
<p>Many papers are archived in <a href="http://arxiv.org/" rel="nofollow">Arxiv.org</a>. A lot of them might also have version histories. But it seems we can't get the update information for one paper when it is updated. Does github support the version history for pdf files? Maybe github can provide the version control for <a href="http://arxiv.org/" rel="nofollow">Arxiv.org</a>.</p>
