New Features

  • Additional configuration options added to define maximum RAM usage and timeouts within a session. See https://docs.glasswall.com/docs/embedded-engine-configuration-management.
    • sysConfig switch linux_memory_limit - Enforces a limit on the memory usage of the process, while processing a session, in GiB. This limit triggers process termination. '0' disables this limit and is the default setting. This setting has no effect on non-Linux platforms.
    • sysConfig switch session_timeout - Enforces a time limit on running a session, in minutes. This limit triggers process termination. '0' disables this timeout where '60' is the default setting.
  • SBOMs are now included as standard in the release package for each of the Embedded Engine libraries. SBOM generation is currently marked as a beta feature.

Fixes and Improvements

  • Fixed issue in PDF to remedy non-conforming files which were failing with the error "Expected to find an EOL terminator found (0x30) instead".
  • Fixed issue in OOXML where some non-conforming files containing empty streams were still regenerated.
  • Changes made to JPEG where JFXX marker segments are now unconditionally removed.
  • Erroneous textSetting policies in Word Search are now rejected rather than the library falling back on default settings.

Defects and Limitations

  • The JavaScript wrapper is currently excluded from the release package. This will be reintroduced in a subsequent release.
  • Archive Manager and 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.
