Latest official NUT release... for too long. Another is brewing - just watch the commits-since count!
WARNING: this is a recent (2021) action on GitHub Releases metadata, to "announce" the
v2.7.4 tag from 2016, so certain REST API actions can be done with it.
If building NUT from scratch, better take a look at the master branch or one of prospect libusb-1.x support branches. And fingers crossed for a 2.7.5 and beyond soon!..
