Impex release information

Release Type: Patch

Release date: 2026-05-26

The IMPEX 5.9.2 release

This is a patch release fixing an ISO install issue and adding more diagnostics around UEFI CA 2023 certificate enrollment on USBProtect stations.

We also added a fallback to the UEFI CA certificate enrollment for the few Generation 1 USBProtect stations that have Secure Boot turned off.

Apart from the ISO install issue we also adjusted the installation to work on hardware without network interfaces.
