<p dir="auto">There seems to be an outdated tutorial page online at <a href="https://matplotlib.org/users/beginner.html" rel="nofollow">https://matplotlib.org/users/beginner.html</a> . It has the old “Matplotlib 2.0.0rc2 is available – Install the release candidate now!“ banner.</p>
<p dir="auto">I guess it’s not reachable from the main page, but it comes up in Google results.</p>
<p dir="auto">On the current live docs, the examples page claims to be from release <code class="notranslate">2.0.2</code>, but it should be <code class="notranslate">2.1</code>: <a href="http://matplotlib.org/examples/index.html" rel="nofollow">http://matplotlib.org/examples/index.html</a></p>
