Looks like they are still on NUT version 2.8.0 so I would guess it is not fixed.
this can be verified by the upscmd -h command in the shell version 2.8.1 is the version that has the fix in it
It does look like it was removed from the know issues on the release notes which I am not a fan of as it seems like it is once again not being tracked on the TrueNAS side of things.
