Release 16

Date of Release: 6 August 2024

General Remarks

This release contains numerous performance improvements and enhancements across the Glasswall Embedded Engine SDK projects.

Note: As of Release 16, Centos 7 is no longer a supported operating system.

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.

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.

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
