<p>Version: 2026-04-02 — v0.9.2</p>
<ul>
<li>FIX: URLhaus (abuse.ch) integration now requires an API key (Auth-Key header); added URLhaus API Key field in Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> Security scanning. Without a key the URLhaus check is skipped gracefully.</li>
