Nut upsuser - Mar 2022 - Incorrect output.voltage readings : CyberPower AVRG900LCD UPS

nut 2.7.4
Ubuntu Linux 21.10
CyberPower CP1500AVRLCD
CyberPower AVRG900LCD

The CyberPower CP1500AVRLCD UPS indicates the expected output.voltage value
of 120.0 VAC.
The CyberPower AVRG900LCD UPS indicates *unexpected* output voltage values
of 130.0 to 139.0 VAC.
Note that input.voltage values fluctuate between 119.0 to 121.0 VAC on both
models (as expected).

Searching the mailing-list archives, it looks like various other
CyberPower UPS models are reporting similar (incorrect) output.voltage
values (*e.g.
https://alioth-lists.debian.net/pipermail/nut-upsuser/2015-December/010020.html
<https://alioth-lists.debian.net/pipermail/nut-upsuser/2015-December/010020.html>*)
but I just want to verify that there isn't a patch and/or configuration
adjustment required for the AVRG900LCD model.

Thanks in advance for your time + effort...

The patch has been merged into the main Git branch, as mentioned here:
https://github.com/networkupstools/nut/issues/439
<https://github.com/networkupstools/nut/issues/439> (also suggests why the
CP1500... doesn't exhibit the problem)

but a new release is still in the works:
https://github.com/networkupstools/nut/issues/1263
<https://github.com/networkupstools/nut/issues/1263>

For reference, CPS UPSes have their own issue tag/label in GitHub, which can
help when looking for problems and patches:
