<blockquote>
<h1>5.9.1 (March 22, 2026)</h1>
<ul>
<li>Fix: batch result format corruption when using cached prepared
statements (reported by Dirkjan Bussink)</li>
</ul>
<h1>5.9.0 (March 21, 2026)</h1>
<p>This release includes a number of new features such as
SCRAM-SHA-256-PLUS support, OAuth authentication support, and
PostgreSQL protocol 3.2 support.</p>
<p>It significantly reduces the amount of network traffic when using
prepared statements (which are used automatically by
default) by avoiding unnecessary Describe Portal messages. This also
reduces local memory usage.</p>
<p>It also includes multiple fixes for potential DoS due to panic or OOM
if connected to a malicious server that sends
deliberately malformed messages.</p>
