About Versions (100)

v2.4.5

2026-02-06

Desktop changes

  • Windows desktop MSI to support headless installation with custom parameters to set up server URL and login mode, an example for this would be msiexec /i "Stirling-PDF-windows-x86_64.msi " /qn STIRLING_SERVER_URL="http://192.168.1.53:2357/" STIRLING_LOCK_CONNECTION=1

STIRLING_SERVER_URL auto sets the URL and STIRLING_LOCK_CONNECTION=1 sets the connection mode to be ONLY self-host server, ensuring no mistaken connections to external servers. Please note this feature is currently in testing, if you have feedback or have tried it please let us know! (Even if it worked perfectly its good to know!)

  • SSO UI changes
  • support for login method restrictions in desktop
  • remembers last entered selfhost URL for easy reconnection

  • New strict mode for PDF/A conversion for issues were conversation isn’t perfect
  • redaction improvements

Bug fixes
