New Features

• Tracked changes support in XLSX files via a new content management policy.
  • A tracked_changes content management policy can now be configured to sanitise, disallow or allow tracked changes content within XLSX files.
  • This feature currently sits behind the enable_ooxml_tracked_changes sysConfig feature toggle (disabled by default). See Configuration Management
  • A subsequent release will introduce tracked changes support in DOCX.
• Significant improvements to Export/Import memory usage and processing times.
  • For complex files such as office xml files with a larger number of structures, significant memory usage reduction (as much as ~80%) and processing time reductions (as much as ~50% and higher where system limits were reached).
  • New implementation currently off by default. See enable_xml_streaming and enable_sisl_streaming in Configuration Management to enable feature via sysConfig feature toggle.
• New API for translating error codes to descriptions.
  • Currently available in C++ and the .NET language wrapper. See GW2RetStatusErrorMsg.

Fixes and Improvements

• Updated Word Search to force interchange_type policy setting to 'xml' where no setting or a different setting is provided.
• Fixed issue that sometimes led to a gw2ret_generalfail (-1) being returned instead of gw2ret_fileRejected (-16) when running a session.
• Fixed issue in PDF where some AllowedIDs were incorrectly reported or missing.
• Improvements to MP3 File determination. Addresses issue where some text files were incorrectly identified as MP3.
• Fixed issue in Word Search that led to additional replacement characters being written out where escaped symbols were used for redaction.
• Fixed issue in Word Search where analyis reports could be missing error descriptions where a file was marked as non-conforming during the CDR process.
• General improvements to Word Search pattern matching.
• Fixed issue in MP4 that could lead to a core dump where using the Export APIs.

Defects and Limitations

• A tracked_changes content management policy is listed under wordConfig in the analysis reports but is not currently enforced.
• The Alpine library is currently excluded from the release package and will be reintroduced in a future release.
• The JavaScript wrapper is currently excluded from the release package and will be reintroduced in a future release.
• The Word Search Java wrapper compatibility is currently limited to JRE8.
• PDFs generated via the MS Outlook Adobe plugin are not supported.
• Word Search analysis XML no longer reports structural content or changes.
• Processing times may be impacted by changes made to licensing functionality.
• Processing files using multiple threads is not supported. Spawning multiple processes is advised in order to facilitate parallel processing.
• Word Search functionality is provided as Beta:
  • 'text' or 'regex' cannot be the same for 'require' or 'allow'/'disallow' as this will regenerate the file and ignore the 'disallow' or 'require' setting
  • | symbol at the start or end of a search term can potentially cause the Engine to hang where using regex search policies
