SignServer Hardware Appliance 5.1.1 Release Notes
JUNE 2025
We are pleased to announce the release of SignServer Hardware Appliance 5.1.1.
Improvements and Corrections
The following lists corrections included in the release.
Starting with this release, it is now possible to use a Windows NFS server with the Next Generation Hardware Appliance for software updates, as well as for backup and restore.
Note on installing 5.1.1 when using Windows NFS servers
The Mender update file must be made available once via NFS service that supports NFS v4.0 (e.g., using Ubuntu on a laptop). This is required so the appliance can properly consume the update file.
After a successful update to 5.1.1, the use of a NFS v4.1/v4.2 server is fully supported.
Upgrade Information
A downgrade of the firmware version of the appliance would require also a downgrade of the HSM firmware version in case the versions between those firmware versions are different. Therefore it would require a factory reset of the appliance.
