Impex release information
Release Type: Patch
Release date: 2026-05-21
The IMPEX 5.9.1 release
This is a patch release fixing two bugs in the 5.9.0 release.
The first bug is a deadlock in the “Identify7Z” engine, the engine that detects encrypted archives. It could happen if one had more than 1000 archives in a folder. This only affected customers who had enabled the Yara rule for detecting encrypted archives.
The other bug is in the DataLock product where cleanup of old flow error files could cause the upload to the final destination to fail.
