# Changelog
## 2026-01-29 - 3.41.3 - fix(dees-pdf-viewer)
use in-memory PDF data for download and print; add robust print wrapper, cleanup and error handling
- Download and Print now use pdfDocument.getData() to create Blob URLs so in-memory PDFs (pdf.js) can be saved/printed.
- Print flow now opens an HTML wrapper with an iframe to allow onafterprint handling, auto-close, popup-fallback and timed cleanup of Blob URLs.
- Added try/catch logging, URL.revokeObjectURL calls and safety timeouts to avoid resource leaks.
- Removed context menu items that relied on the raw PDF URL (Open in New Tab, Copy PDF URL); Download/Print actions now await the async handlers.
## 2026-01-28 - 3.41.2 - fix(dees-pdf-viewer)
account for devicePixelRatio when setting canvas dimensions and scale 2D context to render crisp PDF pages and thumbnails on high-DPI displays
