<h2>6.6.2</h2>
<h2>Bug fixes</h2>
<ul>
<li>
<p>Fixed a memory corruption issue in the C implementation of
<code>_md_shrink()</code> that could lead to segmentation faults and
data loss when items were deleted from a
:class:<code>~multidict.MultiDict</code>. The issue was an edge case in
the pointer arithmetic during the compaction phase -- by
:user:<code>bdraco</code>.</p>

</li>
<li>
<p>Fixed format string compilation errors in debug builds on 32-bit
platforms by using portable <code>%zd</code> format specifiers for
<code>Py_ssize_t</code> values instead of <code>%ld</code> -- by
