<h2>Summary of changes</h2>
<p>The 3.2.0 release contains several new features, configuration options and bug
fixes.
<p>We added SVG support for <b>math formulas</b> and other simple SVG images by
patching the <a href="https://github.com/memononen/nanosvg">nanosvg library</a>.
This is specially relevant for Wikipedia math articles <sup><a href="#fn1">1</a></sup>.

rendered vs the new release where the formulas are shown
properly"src="wiki-math.png"></a>
</figure>
We also added optional support for WebP images via
<a href="https://chromium.googlesource.com/webm/libwebp">libwebp</a>.
You can use the new option <code>ignore_image_formats</code> to
ignore image formats that you may not trust (libwebp had
<a href="https://cve.mitre.org/cgi-bin/cvekey.cgi?keyword=libwebp">some
CVEs recently</a>).
<p>A new <b>scrollbar page navigation mode</b> was introduced to help read
websites as if they are books, reducing the usage of the mouse wheel. To enable
it, set the option <code>scrollbar_page_mode</code> to <code>YES</code>.
Clicking anywhere on the vertical scrollbar with the left mouse button will
scroll the view one page down. With the right mouse button, one page up. You can
also configure how much overlap from the previous page is shown in the next one
with the new option <code>scroll_page_overlap</code>.
<p>The vertical scrollbar can now be placed on the <b>left side</b> of the page
with the option <code>scrollbar_on_left</code>. While this may be strange at
first, I find it more pleasant as it keeps it next to the beginning of the
text where I'm usually already looking while reading.
<p>A new option <code>link_action</code> allows users to define <b>custom
commands to open new URLs</b>. These appear on the link menu when
right clicking an hyperlink. You can define multiple options to create multiple
entries.

for a youtube link, with MPV player being shown while Open in MPV is
selected in the menu"></a>
</figure>
<p>Websites can now be <b>zoomed</b> by using the shortcuts <code>Ctrl +</code>
to make text bigger and <code>Ctrl -</code> to make it smaller, <code>Ctrl
0</code> to reset the normal size. Set the default zoom level with the
<code>zoom_factor</code> option.
<p>The SIGUSR1 signal now causes the current page to be reloaded. This is useful
to implement a <b>live view</b> while editing a web page. Here is a simple way
to do it with the <a href="http://eradman.com/entrproject/">entr(1)</a> tool:
<pre><code>$ ls index.html | entr killall -USR1 dillo</code></pre>
