<p><em>Sourced from <a
href="https://github.com/Stebalien/tempfile/blob/master/CHANGELOG.md">tempfile's
changelog</a>.</em></p>
<blockquote>
<h2>3.19.1</h2>
<ul>
<li>Don't unlink temporary files immediately on Windows (fixes <a
href="https://redirect.github.com/Stebalien/tempfile/issues/339">#339</a>).
Unfortunately, this seemed to corrupt the file object (possibly a
Windows kernel bug) in rare cases and isn't strictly speaking
necessary.</li>
</ul>
<h2>3.19.0</h2>
<ul>
<li>Remove direct dependency on <code>cfg-if</code>. It's still in the
tree, but we didn't really need to use it in this crate.</li>
<li>Add an unstable feature
(<code>unstable-windows-keep-open-tempfile</code>) to test a potential
fix to <a
href="https://redirect.github.com/Stebalien/tempfile/issues/339">#339</a>.</li>
</ul>
