  • New OCR version, significantly more accurate in many cases -- The OCR button will prompt to update. This can be disabled with the NoUpdatePrompt flag in appsettings.xml -- Not supported on Windows XP (will use the older version instead) -- You can choose between multiple modes: Fast (recommended), Best (slow), and Legacy (to simulate the older version)
