Fixes and Improvements

• Updates to file complexity reporting
  • Optimisations around complexity calculation improving end to end processing times and memory usage.
  • Complexity now reported across all engine use cases.
  • Complexity now reported as 'N/A' in non-conforming files.
• Fixed issue in pptx that led to the failure "End of stream ppt/comments/comment1.xml" when running content export where review comments is set to 'allow'.
• Fixed issue in pdf that led to the failure "Viewer preferences object must be a dictionary". A remedy item is now applied to correct the non-conforming structure.
• Fixed issue affecting some pdf files where gw:TotalSizeInBytes was incorrectly computed for some unrecognised objects.
• Fixed issue affecting some non-conforming docx files that led to the failure "End of stream 'document.xml' not reached".
• Fixed issue in xlsm that could lead to the failure "FAILURE_LOG_VALIDATIONFUNCS_1254493994 validateAllChildren failed with error: Segmentation fault occurred".
• Fixed issue in ooxml, where the sanitisation of hlinkClick tags led a schema non-compliance in processed files.
• Fixed issue in ooxml, where the formatting of relationship tags led a schema non-compliance in processed files.
• Updates to ooxml to remove the associated author metadata in review comments, where review_comments is set to 'sanitise'.
• Fixed issue in pptx where a dangling reference to a sanitised embedded file in slideLayout.xml was not cleared.
• Fixed issue in ooxml where a remedy item was reported for an embedded object stream already removed via content management policy.
• Fixed issue in ooxml where some embedded objects were removed despite having valid progIDs and valid extensions.
• Updates to svg to retain the data-supported-dps custom attribute. Where a valid width/height value is present, this attribute is now retained.

Defects and Limitations

• gwConfigurationManagement.xsd describes PPTX slide_notes as a content management policy but this feature is not yet implemented in the current release.
• 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
