    • The Universal download should work for all users. Or you can use the Intel/Apple Silicon downloads for a smaller download/install size if you know which one your Mac has.

    • Mono is no longer required
    • The UI should now feel like a native Linux app

  • PDF import and export have been rewritten to leverage Pdfium
    • This means better support for importing different kinds of PDFs
    • In some cases this means much faster import/export
    • Pdfium is bundled with the NAPS2 download so there is no longer an extra download needed to import non-NAPS2 PDFs
