<h3></h3>
<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>
<li>FIX: Scan modal failed to open with “i18n is not defined” JS error — resolved by declaring i18n from cfg.i18n inside initScanModal().</li>
<li>FIX: PDF security report printed blank — modal is now temporarily moved to document.body before window.print() and restored afterwards so @media print selectors work correctly.</li>
<li>FIX: “Scanning…” text rendered as garbled bytes (double-encoded UTF-8) — replaced with an animated indeterminate progress bar.</li>
<li>IMPROVE: Scan badge button removed from card header; scan result (shield icon + date + status label) now appears as an inline row inside the card metadata block, consistent with the rest of the card layout.</li>

<li>IMPROVE: Top toolbar now shows a compact API keys notice with direct links to Google Cloud Console and abuse.ch, replacing the old generic description block.</li>
