<p dir="auto">If I look at the backend section of the FAQ:</p>
<p dir="auto"><a href="https://matplotlib.org/faq/usage_faq.html#what-is-a-backend" rel="nofollow">https://matplotlib.org/faq/usage_faq.html#what-is-a-backend</a></p>
<p dir="auto">it seems like the backend table is missing notebooks. If I instead go to the backends section of the introduction:</p>
<p dir="auto"><a href="https://matplotlib.org/3.2.1/tutorials/introductory/usage.html#backends" rel="nofollow">https://matplotlib.org/3.2.1/tutorials/introductory/usage.html#backends</a></p>
<p dir="auto">I get a super similar table, but with (I think) a more up-to-date list, including the nbagg and ipympl backends.</p>
<p dir="auto">Tellingly, the <code class="notranslate">&lt;title&gt;</code> for the former page says "Matplotlib 2.0.2 documentation", despite having no version indicator on the URL.</p>
<p dir="auto">Apologies if this is a duplicate — I did try a quick search but did not turn up a similar issue.</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>
