  Reduce processing time and output file size with a new CAD rendering mode optimized for performance—ideal for large or complex DWG files.
• Unlink Table of Contents in Word Documents:
  Render TOCs as plain text, removing hyperlinks while preserving layout—useful for secure or static document exports.
• Automatic JPEG Rotation via EXIF Orientation:
  Ensures correct image orientation by interpreting embedded EXIF metadata automatically during rendering.
