March 2026

​
Features

​
12.7.4.1
January 2026

​
Features

  • Added support for re-routing /dev/shm to the local filesystem as an option for environments with limited and insufficient memory.
  • Improved stability of recognition engine when handling invalid characters.

​
Bug Fixes

  • Fixed a crash when converting some documents to Word.
  • Fixed a crash that could occur when processing certain PDF files.

​
12.7.2.2
November 2025

​
Features

  • Added an option in CompressImageModeEnum to use uncompressed images (CIM_NoCompression) to reduce image processing time
  • Improved auto-detection for page inversion
  • Improved initial checks to avoid layout analysis if not needed by later processing steps
  • Improved parallelization when processing multiple blocks on a page
  • Optimized performance with managing page deletion

​
Bug Fixes

  • Fixed: some barcodes were not properly recognized by the engine
​
12.7.1.1
October 2025

​
Features

  • New parameter added to RTFExportParams: WriteSpaceAtCJTLineBreaks=true/false [default true]. This new option allows for disabling adding a whitespace character during export when linebreaks are detected from the original document.
  • New parameter added to PageProcessingParams : ResolutionDetectionMode=RDM_Auto/RDM_Fast, [default RDM_Auto]. This new option allows for controlling which document resolution detection implementation is used. DocumentArchivingSpeed and TextExtractionFast configurations were changed to use RDM_Fast.
  • Made several changes to the FAST profiles to further optimize them for speed when processing documents.

​
Bug Fixes

The following issues have been fixed:
  • If the image source typically can’t provide a reliable resolution but the ⁠CorrectResolution operation was explicitly turned off, the engine will no longer assume A4 page size and will instead use the original image resolution.
  • Fixed a rare crash that could happen while processing images under specific circumstances and would result in an unhandled internal error
