Fixes and Improvements

• Fixed issue in gif affecting some analysis report content items where gw:TotalSizeInBytes was reported incorrectly.
• Further performance optimisations improving processing times and memory usage where running content export/import.
• Updates to the Java Wrapper to include the GW2RetStatusErrorMsg API.
• Fixed issue causing processing failures where longer policy files could not be loaded.
• Updates to gwConfigurationManagement.xsd and example config.xml policy file.
• Updates to the Java wrapper, adding the libjsg library as a direct dependency. This will better enable signal chaining without specifying LD_PRELOAD when setting up the environment. See Installation - Signal Chaining When Using Java for further details.

Defects and Limitations

• 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 'require' can potentially cause the Engine to hang where using regex search policies
