Version 11.12.0 Changelog (April 1, 2026)

New In This Release

PDF Sanitization

  • The PDF Sanitization feature enables removal of hidden, sensitive, or potentially malicious content from PDF documents.

RTF, MSG, and EML Conversion

  • Introduced built-in conversion capabilities for RTF, MSG, and EML files within the Apryse Office conversion suite.

XLIFF 2.0

  • TransPDF: Implemented full XLIFF 2.0 integration, enabling both the export of document text and the import of translated content using XLIFF 2.0 files.

Handwriting Recognition

  • Added a new Handwriting ICR Module that uses AI to recognize handwriting in PDF files and outputs results in JSON format (HandwritingICRModule.ProcessPDF() or HandwritingICRModule.GetICRJsonFromPDF()).

New Options

  • Added default page and margin size options to OfficeToPDFOptions (SetDefaultMarginBottom, SetDefaultMarginLeft, SetDefaultMarginRight, SetDefaultMarginTop, SetDefaultPageHeight, and SetDefaultPageWidth). These options are useful for RTF, EML, and MSG document conversions, which do not have predefined page or margin sizes.
