<p><em>Sourced from <a
href="https://github.com/rust-fuzz/libfuzzer/blob/master/CHANGELOG.md">libfuzzer-sys's
changelog</a>.</em></p>
<blockquote>
<h2>0.4.5</h2>
<p>Released 2022-10-18.</p>
<h3>Added</h3>
<ul>
<li>Added the ability to tell libfuzzer whether to keep files inputs in
the corpus
or not. See the <code>Corpus</code> type and extended documentation for
the
<code>fuzz_target!</code> macro for details.</li>
</ul>
<h3>Changed</h3>
<ul>
<li>Ensured that there is always at least one inline-never frame on the
stack per
fuzz target. This helps prevent oss-fuzz from &quot;deduplicating&quot;
different bugs
from different fuzz targets into the same bug.</li>
</ul>
