 # Changelog
 
+## 2026-03-09 - 2.0.9 - fix(smartpdf)
+lazily initialize SmartPdf, stop it only when present, and make evaluateOnPage reliably close pages
+
+- Add private ensureSmartPdf() to lazily initialize and start SmartPdf only when PDF methods are called
+- Call ensureSmartPdf() in pdfFromPage() before using smartpdf
+- Stop SmartPdf in stop() only if it was initialized and clear the reference
+- Wrap evaluateOnPage() page operations in try/finally and safely ignore errors from page.close() to avoid resource leaks or uncaught exceptions
+
 ## 2025-01-03 - 2.0.8 - fix(core)
 Ensure consistent browser automation functionality
